When I trigger a build using this plugin, my container is correctly started and environment variables are passed in with a workaround from JENKINS-32393. What happens to me is that at the end of the shell executor build step, the build process hangs indefinitely. I have verified that the last step of my shell executor has completed successfully. Why does the build not finish? If I run the build with strictly the shell executor and run manual commands to mount the workdir/tmp into a docker container, everything works fine. When I use this plugin, something is very wrong.
