J2cl Maven Plugin

This plugins compiles Java sources to optimized JavaScript using https://github.com/google/j2cl/ and https://github.com/google/closure-compiler/. All Java code in this project will be transpiled to JS, and any source in dependencies will be transpiled as well, and all of that JS will then be optimized with the closure-compiler to produce small, efficient JavaScript.

• Goals Overview

  • j2cl:build Translates Java into optimized JS.
  • j2cl:watch Watches for changes in the current project(s), and translates Java to JS when changes occur.
  • j2cl:test Runs JUnit tests as closure-library test suites.
  • j2cl:clean Deletes the plugin's own build cache.
