Upgrade to parent 42 and try again. I had a jar creation issue with is complaining about the 3.2 jar plugin which I think we upgraded in 42. I’m also using maven 3.5.0 and java 9+159 on mac OS X 10.12.5.
> Should I leave it with Java 1.5 as the source and target? I cannot compile on java 9 if I do. Further, are there any arguments to upgrading to commons-parent 42?
Yes, please do. What we want to release now is a bug fix release out
of the 1.3 branch. Topics like Java 9 ought to be resolved in the
trunk. (Btw: What are the issues? Can you publish something on Jira?)
The next time you hear: "Don't reinvent the wheel!"
