I’ve noticed that my build for https://github.com/ensime/ensime-emacs is failing with a permission error
cask exec: error: Failed to execute ert-runner: [Errno 13] Permission denied
but if I manually start up the docker container, check out the git repo, and run the contents of .drone.yml, everything is ok.
Unfortunately the command (cask) that fails isn’t giving me any extra info about what exactly failed: it looks like it might even be a python thing.
So what special magic is drone doing? Especially in the /drone directory?
