Guoxiong Li commented on MNG-7075:
----------------------------------
In the past, when I was only a maven user, I never use the command `mvnDebug`.
So if I want to read the version or help infomation, I used `mvn -v` or `mvn
-h`. Actually, I don't know that maven has the command `mvnDebug`.
Recently, when I want to dive into maven source code and want to become a maven
developer, I used `mvnDebug -version` to debug so that I can see how maven
starts and how maven resolves the config. Then, I created a demo maven project
and used `mvnDebug clean compile` to debug so that I can see how maven executes
the plugins.
Because I had experienced in shell, I tried to read the shell scripts `bin/mvn`
and `bin/mvnDebug` so that I can learn more about the maven. But if someone who
only know java but don't know anything about shell, he/she can't understand the
shell scripts and can only get the meaning of the shell scripts from its name.
So I think `run is run, debug is debug`. We shouldn't add some run cases into
the debug situation, which would confuse both users and new developers.

Could you please point out the mailinglist link about this for me? Thanks a lot.
