Everry time that openjpa-maven-plugin is run, it shows the following warning:
[INFO] — openjpa-maven-plugin:2.2.0-SNAPSHOT:sql (default-cli) @
[WARNING] Could not transfer metadata
path /internal-repository does not exist, and cannot be created.
I've found that this is happening because of an internal-only repository declared in openjpa-kernel's POM.
In the attached patch I just overwrite such repository declaration: I guess there could be a more elegant way to achieve this, anyway...
