The root cause for this PR has to do with this PR#30 and PR#31.

After set -e we need to define the workdir

@shenggwang it's good practice to elaborate a bit on the problem. I honestly don't know why you need to cd after set -e. You can leave a link here (e.g., a stack overflow question of someone with the same problem) or just elaborate on the problem using your own words.

The problem has to do with the directory, for the reason that I added cd. Because by default it was working on \tmp. Thank you for your question, it makes me realise that it shouldn't be on script itself, instead on pom.xml :smile:

Yes! set -e is only a mode, doesn't affect directories, but the new solution is much better ;)

I don't know the reason, by debugging it with pwd, before set -e it is in the correct directory, after that, the directory changed to /tmp. It's weird, I don't know if this have to do with exec-maven-plugin, but I didn't find anything related this issue.
