You can open this sample inside an IDE using the IntelliJ native importer or Eclipse Buildship.

This sample shows how to build a Gradle plugin in the Java language.

greeting-plugin/build.gradle
plugins {
    // Apply the Java Gradle plugin development plugin to add support for developing Gradle plugins
    id 'java-gradle-plugin'
}

repositories {
    // Use jcenter for resolving dependencies.
    // You can declare any Maven/Ivy/file repository here.
    jcenter()
}

dependencies {
    // Use JUnit test framework for unit tests
    testImplementation 'junit:junit:4.13'
}

gradlePlugin {
    // Define the plugin
    plugins {
        greeting {
            id = 'com.example.plugin.greeting'
            implementationClass = 'com.example.plugin.GreetingPlugin'
        }
    }
}
greeting-plugin/build.gradle.kts
plugins {
    // Apply the Java Gradle plugin development plugin to add support for developing Gradle plugins
    `java-gradle-plugin`
}

repositories {
    // Use jcenter for resolving dependencies
    jcenter()
}

dependencies {
    // Use JUnit test framework for unit tests
    testImplementation("junit:junit:4.13")
}

gradlePlugin {
    // Define the plugin
    val greeting by plugins.creating {
        id = "com.example.plugin.greeting"
        implementationClass = "com.example.plugin.GreetingPlugin"
    }
}
