Hey legends, running into a build/pack issue that I need help with - Plumber looks for a license and key in the app plugins folder, same folder is deleted on clean/rebuild. Anyone see the problem here? I can move the license to /bin, but that will be tricky to manage for existing installs (might need a migration, blergh). Any suggestions on how to manage the clean/rebuild removing app_plugins/plumber, when that directory contains files which should be kept?
