We don't have a good source currently no, but something to keep in mind. Ideally we would want to create a common
source for both jib-profiles.js and the gitactions to read from. I would prefer something that can be read both as a
properties file and sourced as a shell script, much like the version-numbers file currently is. That could be done as a
separate change though.
