An issue with node_modules/google-closure-compiler when building

[Igal Alkon]

I have an issue when executing build:

With JAVA:

openjdk version "1.8.0_144"
OpenJDK Runtime Environment (build 1.8.0_144-b01)
OpenJDK 64-Bit Server VM (build 25.144-b01, mixed mode)

Scene imported from external module 'three' but never used
created build/physics-module.native.js, build/physics-module.native.module.js in 15.2s

I'm actually trying to fix an issue with (I assume):

import PhysicsWorker from 'worker!../worker.js';

Cause:

ERROR in ./node_modules/physics-module-ammonext/src/modules/WorldModule.js
Module not found: Error: Can't resolve 'worker' in '/home/wdna/Develop/Games/ste/node_modules/physics-module-ammonext/src/modules'
BREAKING CHANGE: It's no longer allowed to omit the '-loader' suffix when using loaders.
                 You need to specify 'worker-loader' instead of 'worker',
                 see https://webpack.js.org/guides/migrating/#automatic-loader-module-name-extension-removed
 @ ./node_modules/physics-module-ammonext/src/modules/WorldModule.js 5:0-48
 @ ./node_modules/physics-module-ammonext/src/modules/index.js
 @ ./app/main.js

In main application.

Hey, @alkavan, it looks like with recent refactoring I accidentally removed tools folder which is needed by google closure compiler.

You could take it from any of my previous commits or use builds without minifying.
For development I advise you to use npm start command
