Integrating with Groovy and Scala Plugins

Shadow also works well for Groovy and Scala, here are integration examples:

For Groovy:

KotlinGroovy

plugins {
  groovy
  id("com.gradleup.shadow")
}

dependencies {
  // If you don't want the Groovy standard library to be shadowed, please replace `implementation` with `api`.
  implementation(localGroovy())
}

tasks.shadowJar {
  manifest {
    // Optionally, set the main class for the shadowed JAR.
    attributes["Main-Class"] = "com.example.Main"
  }
}

plugins {
  id 'groovy'
  id 'com.gradleup.shadow'
}

dependencies {
  // If you don't want the Groovy standard library to be shadowed, please replace `implementation` with `api`.
  implementation localGroovy()
}

tasks.named('shadowJar', com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar) {
  manifest {
    // Optionally, set the main class for the shadowed JAR.
    attributes 'Main-Class': 'com.example.Main'
  }
}

For Scala:

KotlinGroovy

plugins {
  scala
  id("com.gradleup.shadow")
}

dependencies {
  // If you don't want the Scala standard library to be shadowed, please replace `implementation` with `api`.
  implementation("org.scala-lang:scala-library:2.13.16")
}

tasks.shadowJar {
  manifest {
    // Optionally, set the main class for the shadowed JAR.
    attributes["Main-Class"] = "com.example.Main"
  }
}

plugins {
  id 'scala'
  id 'com.gradleup.shadow'
}

dependencies {
  // If you don't want the Scala standard library to be shadowed, please replace `implementation` with `api`.
  implementation 'org.scala-lang:scala-library:2.13.16'
}

tasks.named('shadowJar', com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar) {
  manifest {
    // Optionally, set the main class for the shadowed JAR.
    attributes 'Main-Class': 'com.example.Main'
  }
}
