Enable Maven deploy on push for CI using GitHub Actions

[saudet]

Also fix build on Windows for TensorFlow 2.1.0
(However, it still fails on GitHub Actions as explained in pull #8.)

With these changes, builds triggered by a git push are executed with mvn clean deploy -Possrh ...
It looks like this: https://github.com/saudet/tensorflow-java/actions/runs/32841274
(Builds triggered by pull requests remain with mvn clean install ...)

To make that work in any given repository, the CI_DEPLOY_USERNAME and CI_DEPLOY_PASSWORD secrets need to be set to valid credentials from https://oss.sonatype.org/ and the org.tensorflow domain: https://help.github.com/en/actions/automating-your-workflow-with-github-actions/creating-and-using-encrypted-secrets @sjamesr Does this sound reasonable?

But that's it! We're now getting snapshots deployed that end users can start testing immediately:
https://oss.sonatype.org/content/repositories/snapshots/org/tensorflow/

Thanks @saudet ! @sjamesr can you check this out and create those two secret variables before merging so we can give it a try?

Meanwhile @saudet , is it possible to modify the script to make it more "green efficient" ? :)

I suggest that we trigger the build only for events on the master branch (so pushes on master and pull requests into master).

Also, is there a way to disable the script automatically on forks, so the CI is only triggered on github.com/tensorflow/java specifically?

[saudet]

For the master branch, sure. About forks, I'm not seeing anything, other than disabling it in the settings:

[karllessard]

For the master branch, sure.

Ok let's add the branch filter at least for now

[karllessard]

OSS credentials are set, just waiting for the branch filter

Ok @saudet, it looks like it is working, please make sure that you delete your secrets from your fork otherwise you might override accidentally the artifacts issued from this repo. Thanks!
