Parallel webpack builds fails.

[cvle]

When running webpack with multiple configs (=parallel) the build fails with the following messages:

And the configuration here:

I am using version 3.0.0-beta.17 and webpack version 2.2.0-rc.0.

Running them sequentially works without issues.

I think i have a similar issue although it is when running multiple instances of awesome-typescript-loader in a single configuration.

[rjokelai]

I'm having a similar issue with multi-compiler webpack configurations. When disabling one or the other, everything works fine. instance option has no effect

[davidspiess]

Same problem here with webpack 1

[sanex3339]

same problem

[vtabary]

I had this problem (3.0.0-beta.17). I fixed it, for now, by using the version 3.0.0-beta.13.

I'm using webpack 2.2.0-rc3

And my tsconfig.json contains :

  "awesomeTypescriptLoaderOptions": {
    "forkChecker": true,
    "useWebpackText": true
  },

And I installed the CheckerPlugin as mentionned here https://github.com/s-panferov/awesome-typescript-loader#configuration

Hope this will help

[FrozenPandaz]

I have this same issue with webpack 2.2.0-rc4 on Windows and the node(boron) Docker Container

[georgiosd]

Same problem here with beta18, workaround above works.

[JohnLouderback]

Same problem here

[ocombe]

Same thing here, rolling back to beta 13 until then

[frenic]

@ThaNarie way worked. It actually speed up my build time so I might even keep it that way.

[inzerceubytovani]

Same problem appears when using array in module exports like:

module.exports = [
    webpackMerge({}, defaultConfig, commonConfig, clientConfig),
    webpackMerge({}, defaultConfig, commonConfig, serverConfig)
  ];

[s-panferov]

This is already fixed in master. Release will be ready soon.

[JohnLouderback]

@s-panferov Any news? Is the release still happening shortly?

[inzerceubytovani]

Look it works now. Great job, thanks!

What version of webpack are you running? I'm having the save issue with the 2.2.1 version
