Subject Re: Is there a Maven plugin for the Java debugger (jdb)?
Date Fri, 11 Oct 2013 18:47:52 GMT
Thank you, Curtis, that looks like an excellent suggestion!

Could you elaborate on the exact <plugin>...</plugin> snippet I would need
to drop into my pom.xml in order to achieve this?

If I could just `mvn exec:exec <Class>`, starting a jdb session on
<Class>.main(), that would be *perfect*.
