Kotlin Meets Gradle

Learn more about custom tasks. The form is: plugins { id «plugin id» version «plugin version» } Where «plugin version» and «plugin id» must be constant, literal, strings. If the current host platform is included in this list the test running tasks are also created. Caching kapt tasks Caching for kapt is currently disabled by default, even with --build-cache, because Gradle does not yet have a way to map inputs and outputs for annotation processors. The plugin provides a top-level script block sourceSets allowing you to configure source sets.

Kotlin Meets Gradle

Future versions of Gradle will remove this restriction. Note that caching :test tasks is also supported. Please avoid using the Convention concept when writing new plugins. Work continues to expand the set of tasks that support build caching. Consider adopting it in your Groovy build scripts before converting them to Kotlin.

If the configurations were defined elsewhere, you could only reference them either by first creating delegating properties via configurations — as opposed to configurations. Can anyone explain the reason suggest anything. The kapt annotation processing tasks are not cached by default since annotation processors run arbitrary code that may not necessarily transform the task inputs into the outputs, might access and modify the files that are not tracked by Gradle etc. Effectively, the default dependency is overwritten. It cannot be used in script plugins, the settings. Note that in this case the parameter should be added to each subsequent build, and any build with disabled incremental compilation invalidates incremental caches.

Migrating build logic from Groovy to Kotlin

This file is required if you're building a re-usable library that other Kotlin modules can depend on, and should be distributed together with the result of translation. All these reasons made me take a deeper look at the new style Gradle offers. Another solution would be to use Gradle scripts written with the and define custom tasks within a build. Consumers of your plugin will also have the chance to reuse the existing task type if they want to add more tasks to the build script. The script first defines a few global variables, mostly containing version numbers, which are used throughout the build file. Within the buildSrc, we now create the custom tasks as Kotlin classes: package com. Annotation processing See the description of kapt.

The plugins {} block must also be a top level statement in the buildscript. The and should be useful to you. The new way to add plugins to a project is much more than a more convenient syntax. How might it help teams—especially big ones—work faster and write better structured, more maintainable builds? Not all presented recommendations and recipes presented in this guide might be applicable to your plugin or your use case. To make this possible, we create the buildSrc directory structure as shown above on the same level the build script already exists. It is constrained, in order to be idempotent produce the same result every time and side effect free safe for Gradle to execute at any time. Plugins often times come with default conventions that make sensible assumptions about the consuming project.

In fact those plugins even go further and abstract the version to be used for the external dependency by exposing an extension property e. Why would I do that? Empty for the main component. It told me to update my kotlin gradle plugin version to 1. The specific convention implementation for a registered plugin can be retrieved by providing the convention class via. It was taken from one of my projects, which is a Kotlin web application based on the toolkit. Next, we need to ensure we are compiling with Kotlin version 1.

This serves as a nice way to group related plugins together. Dokka supports mixed-language projects and can generate output in multiple formats, including standard JavaDoc. Plugins should expose a way to reconfigure the default runtime behavior. In addition to releases, this repo contains old and development versions of the plugin which are not available at the plugin portal. Building Kotlin Multiplatform Projects Using the kotlin-multiplatform plugin for building is described in. You might have noticed that it provides a stronger indication of what those properties mean.

The build was about 5x faster! You might have something like this declared in your buildscript {} block in build. IntelliJ does support the creation of new build. The plugin uses Gradle metadata to publish the artifacts so this feature must be enabled see the section. TaskAction; public class Generate extends DefaultTask { private int fileCount; private String content; private File generatedFileDir; Input public int getFileCount { return fileCount; } public void setFileCount int fileCount { this. You also took a look at possible migration strategies in the light of the structure of builds. If you have already downloaded the compiler manually you can specify the path to its root directory using konan. Note, that the first build won't be incremental.

The references the JavaPluginConvention configuration values exposed by the Java plugin. See also the example projects that use this plugin, e. Running tests The plugin builds a test executable for all the targets specified for the test component. If the plugin you want to configure relies on groovy. If you apply them with apply { plugin.
