Build / Run Issue

I have a large build which runs via Jenkins inside a cowbuilder environment. I periodically have this build fail with an error which looks like the following:

00:10:36.448 _______________________________________________________________________________

The package which triggers the issue is arbitrary— it seems to simply happen whenever, on various different packages. It looks like some kind of a race condition, but it’s unclear to me whether the root cause is in catkin_tools or catkin itself.

I don’t believe I ever saw this with 0.3.x, but we also switched to 0.4.x pretty early on.

I’m not using eatmydata, so all writes to disk should be fully synced, but it’s certainly possible this is coming from an interaction between catkin and the cowbuilder’s copy-on-write fs overlay.

I don’t have concrete steps to reproduce, but please let me know if there are ways I could instrument my build to supply more meaningful diagnostic information.

@130s I have the same issues when using Clion and just solve it. But I don’t think our problem is the same with the one they mentioned.

• Problem:
  • I have source /opt/ros/kinetic/setup.bash line added in my ~/.bashrc. Thus it won’t be the problem. However I have also added /home/USERNAME/catkin_ws/devel/setup.bash(I know it’s not recommended) after former line. And when i start clion byPATH_TO_CLION/clion.sh cmake went wrong and show just the same error ImportError: No module named catkin.environment_cachein clion–cmake bar
• solution:
  • comment out line /home/USERNAME/catkin_ws/devel/setup.bash in ~/.bashrc and start over , problem gone

Thanks for any advice on why this problem occur!

Hello everyone, I am getting this same error, but I am using Windows. After reading the discussion above, I couldn’t figure out how to get rid of this error. I am a newbie at this, so could someone please help me with this issue?
