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());
  };
});
