Config with no entry but only vendor bundles does not output vendor bundle.

[mesozoic-technology]

I have a config that doesn't have an entrypoint for the app, rather just an array of entry points that are dependencies which it should output in a vendor bundle. According to the task it is emitting this file. But when it is complete, I don't see the file anywhere in my filesystem.

This is what shows in my console after running the task:

[16:12:22] Starting 'dependencies-webpack'...

This is my webpack config:

Just a guess, but maybe your files are getting written to memory by webpack and webpack-stream is never picking them up?

I'm having a similar issue at the moment, where webpack will write to disk, but webpack-stream changes webpack to use a MemoryFileSystem on this line.
Plugins that call compiler.outputFileSystem.writeFile then write to memory rather than to disk.

So maybe log out the filesystem object in the after-emit function and see if your files are in there?
