grunt-assemble + grunt-webpack = lost plugin definition in webpack configuration

[StephanGerbeth]

Hi,

i have a strange bug when i run grunt-assemble and grunt-webpack in the same task.

I try to explain it:

• I registered an own task by grunt.registerTask('build', ['assemble', 'webpack']);
• the task abort with the following message Running "webpack:app" (webpack) task Warning: arguments[i].apply is not a function Use --force to continue.
• At first i thought: "Uh there is bug in webpack, i try to fix it!". I analyzed the code and i found a hint here.
• options.plugins has empty objects inside. Usually some plugins should be listed which i defined inside the webpack configuration e.g. dedupe, polyfills, uglify.
• For any reason i changed the order inside my grunt task to grunt.registerTask('build', ['webpack', 'assemble']);
• AND - the complete task is running successfull :)
• But it is really important for me to run assemble at first. So this solution is useless for me. :(

My conclusion:
I think a bug is inside assemble which modifies the plugin definition of other tasks. But i'm not sure, because i can't locate him.

Can you help me to solve this strange one?

This is my repo to reproduce the problem: Link
Run grunt build

Cheers

UPDATE:
I can isolate the bug inside the aggregate helper.
if i remove this helper inside my project everything works fine.
Should i move this issue to the helper-aggregate git repo?
