rosjava: Couldn't find executable named run.py
I'm trying to run a java program but I have this error: [rosrun] Couldn't find executable named run.py below /opt/ros/electric/stacks/rosjava_core/rosjava_bootstrap
As I see I couldn't found run.py. But I just installed the rosjava from the repository for electric.
What can be happening? Where must be the run.py script?
Thank you
