Aborting launch due to failed build.

Hello,

Thanks if someone can solve my problem.

With one of my program, each time I launch the simulator, the result is:

BUILD: Complete
Aborting launch due to failed build.

I observe also that there is no bin directory.
I try also to launch directly the batch command in java directory:
ERROR:stdin:17567: Redifinition of label (code) C_.........path..filename_mc_12_0

What that means?
Thanks for your advice.

Sylvain
