Gradle IntelliJ Plugin

gradle-intellij-plugin

The latest version is 1.0

This project requires Gradle 6.6 or newer

When upgrading to 1.x version, please make sure to follow migration guide to adjust your existing build script: https://lp.jetbrains.com/gradle-intellij-plugin

This plugin allows you to build plugins for IntelliJ Platform using specified IntelliJ SDK and bundled/3rd-party plugins.

The plugin adds extra IntelliJ-specific dependencies, patches processResources tasks to fill some tags (name, version) in plugin.xml with appropriate values, patches compile tasks to instrument code with nullability assertions and forms classes made with IntelliJ GUI Designer and provides some build steps which might be helpful while developing plugins for IntelliJ platform.

Getting started

TIP Create new plugins with a preconfigured project scaffold and CI using IntelliJ Platform Plugin Template.

Here is the manual on how to start developing plugins for the IntelliJ Platform using Gradle.

Also, please take a look at the FAQ.

Usage

Gradle

plugins {
  id "org.jetbrains.intellij" version "1.0"
}

Snapshot version

To get the latest features, use the snapshot version of the plugin 
plugins {
  id "org.jetbrains.intellij" version "1.1-SNAPSHOT"
}

And define the snapshots repository in your settings.gradle file

pluginManagement {
    repositories {
        maven {
            url 'https://oss.sonatype.org/content/repositories/snapshots/'
        }
        gradlePluginPortal()
    }
}

Tasks

Plugin introduces the following tasks

Task Description
buildPlugin Assembles plugin and prepares ZIP archive for deployment.
patchPluginXml Collects all plugin.xml files in sources and fill since/until build and version attributes.
downloadRobotServerPlugin Downloads robot-server plugin which is needed for ui tests running.
prepareSandbox Creates proper structure of plugin, copies patched plugin xml files and fills sandbox directory with all of it.

Marketplace platform provides the IntelliJ Platform Explorer – a search tool for browsing Extension Points inside existing implementations of open-source IntelliJ Platform plugins.

One of its features is the possibility of filtering the plugins by those that utilize Gradle or Gradle KTS build scripts.

As examples of using this plugin, you can also check out following projects:

Contributing

Contributing tips:

You can debug the source code of gradle-intellij-plugin (e.g. put breakpoints there) if you add a reference to your local copy into settings.gradle of your IntelliJ plugin:

includeBuild '/path/to/gradle-intellij-plugin'
