Summary: Depends on https://github.com/facebook/flipper/issues/1914. This sets up the workflows for automatically building, publishing and "closing" the repository on Maven Central, which is a step you usually need to do manually in the web UI. Still need to transfer all the secrets over to this repo for it to work. Pull Request resolved: https://github.com/facebook/flipper/pull/1915 Test Plan: Ran all of this in my this in my fork and released some `0.0.x` versions. - Successful workflow: https://github.com/passy/flipper-1/actions/runs/552170713 - It's actually all on Maven: https://repo.maven.apache.org/maven2/com/facebook/flipper/ Reviewed By: jknoxville Differential Revision: D26367469 Pulled By: passy fbshipit-source-id: d65f64ee8eec1dc71af64b7e0f87473b9c956fec
