Sets up Kotlin’s Java interoperability to strictly follow JSR-305 annotations for increased null safety. May 15, ... One of them is support for writing domain-specific language or DSL. Kotlin DSL script files use the .gradle.kts file name extension. DSL is a computer language devoted to … The same mostly applies to interoperability with Groovy code. Enables support for precompiled script plugins. Open source has a funding problem. Here’s a simple example demonstrating how to set and read extra properties using the map syntax: The Kotlin DSL Plugin provides a convenient way to develop Kotlin-based projects that contribute build logic. Gradle ships with kotlin-compiler-embeddable plus matching versions of kotlin-stdlib and kotlin-reflect libraries. The Gradle Kotlin DSL provides support for writing Gradle build scripts using JetBrains' Kotlin language. For example, the Android Plugin for Gradle is not published to the Gradle Plugin Portal and — at least up to version 3.2.0 of the plugin — the metadata required to resolve the artifacts for a given plugin identifier is not published to the Google repository. Kotlin DSL for the app build.gradle.kts. Using an unexpected version of the kotlin-dsl plugin in a build will emit a warning and can cause hard to diagnose problems. The most recent version is 1.3.72. Usually, if you get a NullPointerException with closureOf {}, using delegateClosureOf {} Think named configurations, named source sets, and so on. However, you can apply model rules from scripts — see the model rules sample for more information. The level of support varies based on the versions of each. Both the Groovy and Kotlin languages support extending existing classes via Groovy Extension modules and Kotlin extensions. Gradle is the official build tool for Android. The Kotlin DSL is fully supported by IntelliJ IDEA and Android Studio. In this tutorial you will use Gradle Kotlin DSL (GKD) in a new Kotlin project to script Gradle builds. The static nature of Kotlin enables both compile time checking and authoring assistance from your IDE, from auto-completion to refactoring and everything in-between. That section also describes which containers support type-safe accessors. These serve a similar purpose to — and have now been superseded by — extensions. Enables SAM (Single Abstract Method) conversion for Kotlin functions in order to allow Kotlin build logic to expose and consume org.gradle.api.Action based APIs. There’s also a Kotlin DSL for Gradle available: Gradle-Script-Kotlin . Configuring plugins without type-safe accessors, Example 4. The following example demonstrates several features of the method on the object target: The maven-plugin sample demonstrates the use of the withGroovyBuilder() utility extensions for configuring the uploadArchives task to deploy to a Maven repository with a custom POM using Gradle’s core Maven Plugin. Gradle Kotlin DSL. If you need to eagerly configure or register container elements simply replace existing() with getting() and registering() with creating(). To demonstrate, the following sample adds the google() repository — where the Android plugin is published — to the repository search list, and uses a resolutionStrategy {} block to map the com.android.application plugin ID to the com.android.tools.build:gradle: artifact available in the google() repository: In fact, the above sample will work for all com.android. For example, you can get hold of the implementation configuration via configurations.implementation. Featured on Meta New Feature: Table Support. The following sample demonstrates how to reference and configure artifact configurations without type accessors: The code looks similar to that for the type-safe accessors, except that the configuration names are string literals in this case. More generally, between any plugin that transitively depends on kotlin-stdlib and its version shipped with Gradle. Declare plugin dependencies in the root build script using the, Example 12. The Gradle Kotlin DSL leverages the Kotlin language and its tooling to provide just this. Kotlin DSL brings the simplicity of the Kotlin language syntax and rich API set right into the script files on top of that code completion makes it perfect to work with Gradle script files. The Kotlin DSL currently supports type-safe model accessors for any of the following that are contributed by plugins: Dependency and artifact configurations (such as implementation and runtimeOnly contributed by the Java Plugin), Project extensions and conventions (such as sourceSets), Elements in the tasks and configurations containers, Elements in project-extension containers (for example the source sets contributed by the Java Plugin that are added to the sourceSets container). It automates the publication of the metadata necessary to make your plugins usable with the plugins {} block. It depends on how they have been published and, specifically, whether they have been published with the necessary plugin marker artifacts. So the Kotlin code looks like this: Declare plugin dependencies in the root build script using the, Example 9. If you are among those people who has no idea of how to write Gradle in groovy then kotlin DSL is the one for you. Name initialization scripts according to the pattern *.init.gradle.kts or simply init.gradle.kts. Both IntelliJ IDEA and Android Studio — which is derived from IntelliJ IDEA — will detect when you make changes to your build logic and offer two suggestions: Reload script dependencies when editing a build script. Consider the sample build script shown above that demonstrates the use of type-safe accessors. ", which then is put into the id (plugin: String) … This file (known as a script plugin), … Groovy implements named arguments in a non-type-safe way based on a Map parameter, which means they cannot be combined with default arguments. You can silence the warning by setting the experimentalWarning property of the kotlinDslPluginOptions extension to false as follows: Gradle embeds Kotlin in order to provide support for Kotlin-based scripts. For example, some third-party plugins written in Groovy expect closure arguments. He’s very passionate about learning new things as often as possible and a self-appointed Kotlin … Many of the objects, functions and properties you use in your build scripts come from the Gradle API and the APIs of the applied plugins. Here are some examples that illustrate the situations in which configuration avoidance applies: For all other containers than tasks, accessors for elements are of type NamedDomainObjectProvider and provide the same behavior. Adds the kotlin-stdlib-jdk8, kotlin-reflect and gradleKotlinDsl() dependencies to the compileOnly and testImplementation configurations, which allows you to make use of those Kotlin libraries and the Gradle API in your Kotlin code. Mixing Kotlin DSL scripts with Groovy-based scripts. As long as the combination is compatible everything should work. Example 1. The Groovy DSL allows you to reference many elements of the build model by name, even when they are defined at runtime. Using type-safe model accessors, Example 2. Here’s an example: Both the Groovy and Kotlin languages support named function parameters and default arguments, although they are implemented very differently. Mapping plugin IDs to dependency coordinates, Example 14. Open source has a … You can see which plugins add which properties to source sets in the SourceSet reference documentation. Kotlin DSL is fully supported in Intellij IDEA and Android Studio. In addition, the Kotlin DSL provides several ways to opt into Groovy semantics, which we look at next. These two utility functions are useful for configuration closures, but some plugins might expect Groovy closures for other purposes. When mixing languages in your build logic, you may have to cross language boundaries. We look at each of those ways next, using the tasks container as an example. Groovy DSL: .gradle. What follows is an example of this approach using three subprojects and three plugins. Note that it’s necessary to specify the type of the task explicitly, otherwise the script won’t compile because the inferred type will be Task, not Test, and the testLogging property is specific to the Test task type. Other IDEs do not yet provide helpful tools for editing Kotlin DSL files, but you can still import Kotlin-DSL-based builds and work with them as usual. For any other situation, keep reading. build.gradle, settings.gradle; Kotlin DSL: .gradle.kts There’s been quite some months already since Gradle announced that they were working on supporting Kotlin to write Gradle Scripts, by using a version of the language that has been recently revamped to Kotlin DSL.. At the beginning things where quite complicated, but nowadays, with latest versions of Kotlin DSL (at the time of writing this the version is 0.12) the idea is more mature. That also applies to the settings file — for example settings.gradle.kts — and initialization scripts. Gradle’s Kotlin DSL provides an alternative syntax to the traditional Groovy DSL with an enhanced editing experience in supported IDEs, with superior content assist, refactoring, documentation, and more. See the Plugin Management section of the Gradle user manual for more information on the pluginManagement {} block and what it can be used for. Groovy closures and Kotlin lambdas are automatically mapped to arguments of that type. Plugins fetched from a source other than the Gradle Plugin Portal may or may not be usable with the plugins {} block. For our example, we'll create a simple tool for constructing SQL queries, just big enough to illustrate the concept. In our sample build script, we want to configure a source set named main within the source set container, which we can do by using the named() method in place of an accessor, like so: All elements within a container-based project extension have a name, so you can use this technique in all such cases. Cross project configuration is a mechanism by which you can configure a project from another project’s build script. E.g. org.gradle.api.artifacts.component. The IDE won’t be able to help you discover the available configurations in this situation, but you can look them up either in the corresponding plugin’s documentation or by running gradle dependencies. Just like the Groovy-based equivalent, the Kotlin DSL is implemented on top of Gradle’s Java API. Calling a Groovy extension from Kotlin, Example 20. 品尝差异 The Kotlin DSL provides the withConvention(T::class) {} extension function to do this: This technique is most commonly required for source sets that are added by language plugins other than the Java Plugin, e.g. We recommend against enabling the incubating configuration on demand feature as it can lead to very hard-to-diagnose problems. To do that, you need to know the names and/or types of the configured model elements. Long story short, I removed groovy from my Gradle build tool in my Android project, and replaced it with Kotlin. Specify the version in yout gradle-wrapper.properties: The compatibility guarantees provided by Kotlin apply for both backward and forward compatibility. The Kotlin DSL replaces such dynamic resolution with type-safe model accessors that work with model elements contributed by plugins. Taking this approach means that you won’t be able to use type-safe accessors for model elements contributed by the plugins. Our approach is to only do backwards-breaking Kotlin upgrades on a major Gradle release. without the package name part. For IDE problems outside of the Kotlin DSL script editor, please open issues in the corresponding IDE’s issue tracker: Lastly, if you face problems with Gradle itself or with the Kotlin DSL, please open issues on the Gradle issue tracker. Some plugins expect simple closures, as with the Bintray plugin: In other cases, like with the Gretty Plugin when configuring farms, the plugin expects a delegate closure: There sometimes isn’t a good way to tell, from looking at the source code, which version to use. As for project extensions and conventions themselves, you can discover what elements are present in any container by either looking at the documentation of the applied plugins or by running gradle kotlinDslAccessorsReport. I am a tester a nd have been coding for a living for the past couple of years now. This webcast introduces: Creating a Gradle Kotlin DSL build from scratch The embedded Kotlin compiler is known to work on Linux, macOS, Windows, Cygwin, FreeBSD and Solaris on x86-64 architectures. Changing something in the buildSrc directory also has an impact as it invalidates build-script caching. Recently, I decided to convert one of my multi-module projects to use Kotlin DSL for Gradle. Using Kotlin and a compatible IDE for your build scripts bestows quick documentation, completion, error highlighting, and refactoring. Step by step Android groovy to kotlin DSL. We will always clearly document which Kotlin version we ship and announce upgrade plans before a major release. org.gradle.api.artifacts.dsl. You can unsubscribe at any time. The main reason for this is the slower script compilation for Kotlin DSL. You accomplish both steps by configuring a pluginManagement {} block in the build’s settings script. The Overflow Blog Ciao Winter Bash 2020! For example, this includes any configurations you might define in your own build script. You must instead fall back to declaring your plugin dependencies using the buildscript {} block in the root project build script. Kotlin DSL brings the simplicity of the Kotlin language syntax and rich API set right into the script files on top of that code completion makes it perfect to work with Gradle script files. Use of internal Kotlin DSL APIs in plugins and build scripts has the potential to break builds when either Gradle or plugins change. Disabling the warning about the use of experimental Kotlin compiler features, Example 18. Browse other questions tagged android android-studio build.gradle gradle-kotlin-dsl kotlin-multiplatform or ask your own question. Kotlin + Gradle: a technology combination sure to foster developer happiness and productivity. Here we provide a reference of its contents; use it as a reminder when writing Gradle … Another option when dealing with problematic plugins that assume a Groovy DSL build script is to configure them in a Groovy DSL build script that is applied from the main Kotlin DSL build script: The Kotlin DSL is known to be slower than the Groovy DSL on first use, for example with clean checkouts or on ephemeral continuous integration agents. If you can’t find a type-safe accessor, fall back to using the normal API for the corresponding types. 1) settings.gradle. The Gradle build model makes heavy use of container objects (or just "containers"). As the following sample shows for the sourceSets {} and java {} blocks from the original example build script, you can use the configure() function with the corresponding type to do that: Note that sourceSets is a Gradle extension on Project of type SourceSetContainer and java is an extension on Project of type JavaPluginExtension. Edit Page Using Gradle. Groovy DSL script files use the .gradle file name extension. To call a Kotlin extension function from Groovy, call it as a static function, passing the receiver as the first parameter: Kotlin extension functions are package-level functions and you can learn how to locate the name of the type declaring a given Kotlin extension in the Package-Level Functions section of the Kotlin reference documentation. Builds with slow configuration time might affect the IDE responsiveness, so please check out the performance section to help resolve such issues. Another way to interact with containers is via Kotlin delegated properties. The goal is to instruct your build on how to map the com.android.application plugin identifier to a resolvable artifact. Container-based project extensions, such as SourceSetContainer, also allow you to configure the elements held by them. To call a Kotlin function that has named arguments from Groovy, just use a normal method call with positional parameters. If you can run the build successfully from the command line but your script editor is complaining, then you should try restarting your IDE and invalidating its caches. Existing Java code can be called from Kotlin in a natural way, and Kotlin code can be used from Java rather smoothly as well. You can find all the details on the source code. You can then find out the type of a given task by running gradle help --task , as demonstrated here: Note that the IDE can assist you with the required imports, so you only need the simple names of the types, i.e. Read the Gradle Kotlin DSL Primer and follow the This chapter provides details of the main Kotlin DSL constructs and how to use it … Configures the Kotlin compiler with the same settings that are used for Kotlin DSL scripts, ensuring consistency between your build logic and those scripts. The Kotlin Gradle plugin 1.4.21 works with Gradle … It aims to provide Gradle users with a rich, flexible and statically-typed approach to developing build logic in conjunction with the best IDE and tooling experience possible. An extreme example would be a build that uses tasks and plugins that are implemented in Java, Groovy and Kotlin, while also using both Kotlin DSL and Groovy DSL build scripts. s1m0nw1. Using the plugins DSL: plugins { id ( "org.gradle.kotlin.kotlin-dsl") version "2.0.0" } Using legacy plugin application: buildscript { repositories { maven { url = uri ( "https://plugins.gradle.org/m2/") } } dependencies { classpath ( "org.gradle.kotlin:gradle-kotlin-dsl-plugins:2.0.0") } } apply ( plugin = "org.gradle.kotlin.kotlin-dsl") The 3 files written in groovy will be migrated to kotlin DSL. Such APIs can then be used uniformly from both the Kotlin and Groovy DSLs. The following sample demonstrates how you can use the named() method to configure existing tasks and the register() method to create new ones. There’s been quite some months already since Gradle announced that they were working on supporting Kotlin to write Gradle Scripts, by using a version of the language that has been recently revamped to Kotlin DSL.. At the beginning things where quite complicated, but nowadays, with latest versions of Kotlin DSL … It is checked periodically (at most every 24 hours) and log files are deleted if they haven’t been used for 7 days. We will use the lates Gradle version, as it includes the latest Kotlin DSL version. Use of the plugins {} block to declare Gradle plugins significantly improves the editing experience and is highly recommended. If the above doesn’t work and you suspect an issue with the Kotlin DSL script editor, you can: Check the logs in one of these locations: $HOME/Library/Logs/gradle-kotlin-dsl on Mac OS X, $HOME/AppData/Local/gradle-kotlin-dsl/log on Windows. Saran saya, gunakan Gradle versi 5.0 karena sudah mendukung Kotlin DSL 1.0.. Di sini kita akan fokus pada 3 (tiga) file yang terdapat pada proyek tersebut yaitu settings.gradle, build.gradle (project), dan build.gradle (app).Ketiga file tersebut merupakan Gradle scripts yang secara default dituliskan dengan Groovy. Simon is a software engineer based in Germany with 7 years of experience writing code for the JVM and also with JavaScript. Declare additional plugin repositories, Example 10. The kotlin package from those modules is visible through the Gradle classpath. Playing Gradle Script with Kotlin DSL in Android Project. This makes it easier to keep plugin versions consistent across projects within a build. The KotlinClosure0 to KotlinClosure2 types allows adapting Kotlin functions to Groovy closures with more flexibility. The following sample is exactly the same except that is uses the apply() method to apply the plugin. In order to build a Kotlin project with Gradle, you should apply the Kotlin Gradle plugin to your project and configure dependencies.. Plugin and versions. Any model elements contributed after that point do not work with type-safe model accessors. Compile time error Auto completion; Source navigation; Possibility to use extensions; You have some idea of what you are doing ️; Highly extendable We recommend that you apply the following conventions to get better IDE support: Name settings scripts (or any script that is backed by a Gradle Settings object) according to the pattern *.settings.gradle.kts — this includes script plugins that are applied from settings scripts. will resolve the problem. Language features and tooling may change in future Kotlin versions. The Kotlin DSL provides specific syntax for working with these types of properties, which we look at in the following sections. As seen above, the Kotlin DSL provides accessors only for convention objects on Project. As mentioned in the limitations, you must import your project from the Gradle model to get content-assist and refactoring tools for Kotlin DSL scripts in IntelliJ IDEA. Project extensions and conventions, Example 5. If so, in my case the issue was that I accidentally included the user / password into the systemProp.http.proxyHost URL instead of splitting them out into the systemProp.http.proxyUser and … Kotlin Expertise Blog - In this article, I am taking a look at the Gradle Kotlin DSL as an alternative to the classic Groovy approach: It offeres much better support in IDEs as it is backed by a statically typed … If you run into trouble or discover a suspected bug, please report the issue in the Gradle issue tracker. Kotlin is a type safe language which means that we need to be more strict now on our scripts, specially when migrating Groovy ones. You can use string literals for configuration names in dependency declarations and within the configurations {} block. Create a file, fabric.gradle , in the module where you apply the io.fabric plugin. The build script can not use type-safe accessors in this case because the apply() call happens in the body of the build script. In this case, there’s no need to import the Test task type as it is part of the Gradle API and is therefore imported implicitly. Some of the Gradle core plugins expose configurability with the help of a so-called convention object. This means that you can configure tasks in the same way as you do for source sets, as you can see in this example: We are using the Gradle API to refer to the tasks by name and type, rather than using accessors. You have to use other techniques instead, as demonstrated here: Type-safe accessors are unavailable for model elements contributed by the following: Plugins applied via the apply(plugin = "id") method, Script plugins, via apply(from = "script-plugin.gradle.kts"), Plugins applied via cross-project configuration.
