Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.pukkaone:closure-compiler-maven-plugin:1.0.0'
	}

	dependencies {
		implementation("com.github.pukkaone:closure-compiler-maven-plugin:1.0.0")
	}

	<dependency>
	    <groupId>com.github.pukkaone</groupId>
	    <artifactId>closure-compiler-maven-plugin</artifactId>
	    <version>1.0.0</version>
	</dependency>


                            
    libraryDependencies += "com.github.pukkaone" % "closure-compiler-maven-plugin" % "1.0.0"


                            
    :dependencies [[com.github.pukkaone/closure-compiler-maven-plugin "1.0.0"]]

Readme

Google Closure Compiler Maven Plugin

This project is forked from https://github.com/gli/closure-compiler-maven-plugin to implement additional features.

Entry point configuration

Configure the plugin to include only transitive dependencies of specified entry points.

<entryPoints>
  <entryPoint>application.Main</entryPoint>
</entryPoints>

goog.require returns namespace

Patched Closure Compiler so goog.require can appear inside goog.scope, and goog.require returns the namespace so you can assign it to a variable. For example:

goog.provide('some.Example');

goog.scope(function() {
  var Vec2 = goog.require('goog.math.Vec2');

  some.Example = function() {
    console.log(new Vec2());
  };
});

See https://code.google.com/p/closure-compiler/issues/detail?id=674
