I get “MyEclipse Create Process:Exception occurred executing command line.” trying to run a main or a unit test (version 6.0.1 GA).
The problem went away when I realized that the project was using two J2EE libraries “JAVA EE 5 Libraries” and “J2EE 1.4” (both seem to be in the myeclipse install except the former doesn’t show up in the “add library” dialog). Getting rid of one solved the problem.
How they both got there, I haven’t a clue.
Please let me know if this is a bug or I should become a florist.
