This document help Ray Java developers release Ray Java. Note that we assume you release it on your local laptop.

If you have installed GPG, you can skip this step.

Install gpg software on your laptop. https://gpgtools.org/ Create your own key pair of GPG. Distribute it to a key server so that users can validate it.(Follow the guide of GPG software)

Post a PR to bump the version to the release branch and merge it. Change all of the version numbers of pom.xml files and pom_template.xml files. (These files are under java/directory)

Make sure you are under the Ray root source directory.

export OSSRH_KEY=xxx
export OSSRH_TOKEN=xxx
export TRAVIS_BRANCH=releases/x.y.z  # Your releasing version number
export TRAVIS_COMMIT=xxxxxxxxxxx     # The commit id
git checkout $TRAVIS_COMMIT
sh java/build-jar-multiplatform.sh multiplatform
export GPG_SKIP=false
cd java && mvn versions:set -DnewVersion=x.y.z && cd -
sh java/build-jar-multiplatform.sh deploy_jars

Note that you should set the TRAVIS_BRANCH and TRAVIS_COMMIT to the correct values.

This is an example version(ray-1.4.0) we have released:

export TRAVIS_BRANCH=releases/1.4.0
export TRAVIS_COMMIT=3a09c82fbfce8f00533234844729e6d99fb0f24c
git checkout $TRAVIS_COMMIT
sh java/build-jar-multiplatform.sh multiplatform
export GPG_SKIP=false
cd java && mvn versions:set -DnewVersion=1.4.0 && cd -
sh java/build-jar-multiplatform.sh deploy_jars
