I'm not sure this is the real issue as gradle should mot require to have stuffs pushed to the local maven repo

@lburgazzoli This is a problem of javadoc, and this PR try to find the problem of javadoc with publish to local maven. Does make sense?

[lburgazzoli]

can you remove this since is should not be required?

it should not be required to publish to local maven to validate javadoc, you can probably leverage the javadoc task for this purpose.

also ideally sanity check should be performed before the build and test phase to avoid wasting compute resources and time

Check the error of javadoc:
