Hello,

I am running nodebb 1.8.1 and developing few custom plugins. To build I generally use ./nodebb build from command line.

When there is an error, I sometimes get the following message:

D:\nb>nodebb build "javascript"
started

This message is very generic and does not give me any clue were to look. I often resolve this issue by exhaustive search over my new code, specially looking at style and template files to find the error. I am however refactoring large part of my code and looking at diffs is becoming very time consuming if not impossible.

Is there an easy way to make uglify.js more verbose so it can tell me which file is breaking the build?

Any hint would be appreciated.

Thank you.
