Closure Compiler Jar Download [WORK]

I have hit this issue now for the third time (And I still have on hold 2 other plugins because of this). It seems like the closure compiler (minification) running on the plugin editor when submitting a new version does not support some of the new javascript stuff like Array.prototype.map()
As some of you might know, Closure compiler can produce highly-optimized and efficient code in advanced compilation mode, but it requires following several rules and annotating some parts of the code to help closure recognize types of var for better optimization. One day I thought to try to make it work with three.js.
So i am curios whether the three.js community is interested in closure ? I understand that closure annotations will never be merged in the base project, but maybe I (with some support) could maintain a fork?
It supports new features in ES2015, such as let, const, arrow functions, andprovides polyfills for ES2015 methods not supported everywhere. To help youwrite better, maintainable and scalable code, the compiler also checks syntax,correct use of types, and provides warnings for many JavaScript gotchas. To findout more about the compiler itself, including tutorials, head to Google Developers.
Note that the JS version is experimental. It may not perform in the same way asthe native Java version, but we believe it's an interesting new addition to thecompiler landscape, and the Closure team will be working to improve and supportit over time.
If you'd like to migrate from google-closure-compiler (which requires Java),you'll have to use gulp.src() or equivalents to load your JavaScript before itcan be compiled. As this compiler runs in pure JavaScript, the compiler cannotload or save files from your filesystem directly.
For more information, check out Usage,supportedFlags, or a demoproject. Not all flags supported in the Java release are currently availablein this experimental version. However, the compiler will let you know viaexception if you've hit any missing ones.
Google's closure compiler API gives developers fine-grain control over the compression level of source code run through the compiler. With Cmd 7.0.0 you can easily change compression levels to enhance code obfuscation and reduce footprint size to meet your requirements.
Additional logging has been added to Cmd 7.0.0 to provide better introspection of the compilation process, compression level, transpilation, etc. when the closure compiler is set as the compressor type.
The warning_level indicates the amount of information you want from the compiler about possible problems in your code. The warning_level parameter only has an effect when an output_info parameter with a value of warnings is also supplied. There are three possible warning levels:
The Dojo build system is giving me INTERNAL COMPILER ERROR on my ES6 code. I figure this might be due to a buggy version of the Closure compiler shipped with Dojo, so I downloaded the latest version of the Closure compiler and I now get a bunch of errors in the dojo code itself.
Since the version 3.5, Jawr provides by default a postprocessor to compress your JS bundles with Google Closure Compiler.
The google closure compiler postprocessor is a global postprocessor, which means that it will be launched at the end of the bundling process. This google closure compiler postprocessor is defined as a global postprocessor, because in advance mode, the compiler will check the JS functions to remove the dead code.
Externs files define APIs external to your JavaScript. They provide the compiler with the type information needed to check usage of these APIs in your JavaScript, much like forward declarations do in C++.
JSDoc tags support in PhpStorm/WebStorm 5.0 has been improved to make your coding experience better. When something is known about current context, more relevant completion options will be shown and more static errors will be reported instantly. In the upcoming PhpStorm/WebStorm 5.0 EAP nearly all of Google Closure compiler JSDoc tags are supported. In addition to @param, @type, @extends etc., following tags will also be handled better:
Google has a trio of open source technologies for developers who write large-scale JavaScript applications. Included in the first release were the Closure Compiler, a sophisticated JavaScript compiler, the Closure Library, a huge JavaScript code library designed for use with that compiler, and Closure Templates, a template system implemented in JavaScript and Java.
