Production gradle build doesn't work after upgrade to 4.6.0/1

[jkili]

Overview of the issue

I have upgraded from 4.5.1 to 4.6.0 (and now this afternoon up to 4.6.1) and everything works perfectly, except the new webpack.prod.js (yarn webpack:prod or via gradle gradlew -Pprod bootRepackage -x test) which runs and never completes. It does get an error which I have shown below but it doesn't stop the process from continuing to run:

yarn webpack:prod v0.23.2
$ yarn run cleanup && yarn run webpack:prod:main 
yarn run v0.23.2
$ rimraf build/{aot,www}

Motivation for or Use Case

No longer can perform production builds. I want to keep using the jhipster webpack/gradle configurations un-modified and this has worked up till this release.

Reproduce the error

As above. I have included "ngx-chips": "1.4.5" in package.json. This plugin works correctly after dev builds/yarn start.

Seems like you have an issue from modification you have done so I suggest you take this to stack overflow. I suggest you also provide more details about what you have done if you expect help

This is not a bug or feature request and hence this is not the correct forum for this.
Please use Stack overflow for this. Tag the question with jhipster and someone will help you out there.

This helps us to keep issue tracker clean. Also stack overflow will give your query a larger audience.

I'm sorry but I can't reproduce:

• I used your .yo-rc.json and ran ./gradlew -Pprod bootRepackage. Everything works.
• I don't totally understand what you write about ngx-chips: I guess this is a library you added - are you sure this isn't causing the issue? Could you try removing it?

I'm closing this as I can't reproduce, of course please re-open if you have more information to help me.

Ok, no worries. This is the first upgrade which hasn't worked for me so thought there might be an issue, but happy for you to close.

-Update-
@deepu105 You were right. An update to webpack.common made ages ago keeps on being merged in that was causing the issue. Back to vanilla webpack config and it works perfectly.

Appreciate the work you both do. Thank you.
