How to execute gradle task during project import in Intellij Idea

Question

Let's assume my build.gradle file contains task generateSources which as name suggests generates additional java files. It's easy to ensure that generateSources is executed before compileJava: compileJava.dependsOn generateSources. How can I make sure generateSources is called when importing project into Intellij Idea as well?

Answer 1

To elaborate on @vladimir-sitnikov's answer: I added the idea-ext-plugin to my root project:

apply plugin: 'org.jetbrains.gradle.plugin.idea-ext'

// ...

buildscript {
  dependencies {
    classpath "org.jetbrains.gradle.plugin.idea-ext:org.jetbrains.gradle.plugin.idea-ext.gradle.plugin:0.7"
  }
}

Because without that I wasn't able to use it in my sub project, but now it works like this:

idea.project.settings.taskTriggers {
  beforeSync tasks.getByName("generateSources")
}

Adding the plugin to the sub-project only didn't do it.

Note: The plugin's documentation is kind of limited, but in "DSL spec v. 0.2" is stated

• beforeSync - before each Gradle project sync. Will NOT be executed on initial import

Didn't try that, but it works with existing projects.

This can be done via id("org.jetbrains.gradle.plugin.idea-ext") plugin (https://github.com/JetBrains/gradle-idea-ext-plugin).

See sample code in Gradle sources: https://github.com/gradle/gradle/blob/135fb4751faf2736c231636e8a2a92d47706a3b9/buildSrc/subprojects/ide/src/main/kotlin/org/gradle/gradlebuild/ide/IdePlugin.kt#L147

You can set the task in Gradle tool window: Execute Before Sync:
