Steps to reproduce

How can the issue/bug be reproduced?

  1. Complete first tutorial (http://wiki.ros.org/pilz_robots/Tutorials/ModelYourApplicationWithPRBT)
  2. Complete second tutorial (http://wiki.ros.org/pilz_robots/Tutorials/MoveRobotWithPilzCommand_planner)
  3. Try to use the launch file: roslaunch pilz_tutorial my_application.launch

Expected behavior

I think the launch file should be executed, RViz should show up and I should be able to use the pilz path planner using RViz or Python.

Observed behavior

The launch file / the package can't be found. The following error appears in terminal:

RLException: [my_application.launch] is neither a launch file in package [pilz_tutorial] nor is [pilz_tutorial] a launch file name

RViz doesn't open up. The package can't even be found using rospack find pilz_tutorial or roscd pilz_tutorial.

My attempts at solving the issue

I have tried to find a solution by looking for other people who had a similiar issue. In most cases, people solved this problem of not finding the launch file by sourcing the setup.bash file by executing the following command: ~/catkin_ws/devel/setup.bash and then trying to use the launch file again. I did exactly this, but it doesn't seem to work. I even added the line to the ~/.bashrc file, so that it gets executed every time I open a new terminal window, but it still doesn't find it.

Perhaps using catkin_make or catkin build makes a difference?

Hopefully you know the solution to the problem or maybe you can give me a hint. Thank you very much in advance!

Never mind, I found the mistake. The CMakeLists.txt file inside the directory ~/catkin_ws/src/pilz_tutorial was gone. I recreated the package using catkin_create_pkg pilz_tutorial prbt_moveit_config and sourced the setup file again using source ~/catkin_ws/devel/setup.bash and it works now! Sorry for bothering you.
