Some users have reported an error on package builds that looks like this:
Source path does not exist: resources\android\xxx\xxx.png
This happens when the file paths for resources in your
config.xml file contain the
\ character. Our builds happen in a Linux environment, so
/ is expected instead.
To resolve this issue, open
config.xml and modify each path to use
/. Once this is done, re-commit and push, then try the build again.
