Lots of times if you have build errors its because the various paths defined in the POM file don’t exist on your system. For example, the error says

cp: cannot create regular file '/home/ursim/ursim-5.11.ur0.108249/.urcaps/com.UniWest.lightup.jar': No such file or directory

So make sure your directory is exactly that. Often times it’s just a different ursim-5.11.XXXX file.

Your issue is that in your build the project aims to generate a URCap and automatically deploy it to URSim.
On the build settings, you can comment out the URSim deployment, so the URCap will build and the output will just be within the project folder.
Then you can copy the generated URCap to a USB stick and install it from Polyscope.

Hello
You are totally correct, i guess i was a bit tired when doing this…
old path /home/ursim/ursim-5.11.ur0.108249/.urcaps/com.UniWest.lightup.jar
correct path /home/ur/ursim/ursim-5.11.ur0.108249/.urcaps/com.UniWest.lightup.jar
thanks!
