Releasing

Steps

1. Set versions:

   export RELEASE_VERSION=A.B.C
   export NEXT_VERSION=A.B.D-SNAPSHOT

2. Check out the release branch.

   git checkout -b release-$RELEASE_VERSION

3. Update CHANGELOG.md with changes since the last release. Follow the existing CHANGELOG.md format, which is derived from this guide

4. Update documentation and Gradle properties with RELEASE_VERSION

   sed -i "" \
     "s/VERSION_NAME=.*/VERSION_NAME=$RELEASE_VERSION/g" \
     gradle.properties

5. Tag the release and push to GitHub. Submit and merge PR.

   git commit -am "Prepare for release $RELEASE_VERSION."
   git tag -a nostrino-$RELEASE_VERSION -m "Version $RELEASE_VERSION"
   git push && git push --tags
   gh pr create -f && gh pr merge --auto --squash

6. Wait until the PR created above is merged, then trigger the Publish a release action against the new tag. This will publish to Sonatype Nexus, closing and releasing the artifact automatically to promote it to Maven Central. Note that it can take 10 to 30 minutes or more for the artifacts to appear on Maven Central.

7. Checkout main branch and pull the latest changes

   git checkout main
   git pull

8. In a new branch, prepare for the next release and push to GitHub. Submit and merge PR.

   git checkout -b next-version-$NEXT_VERSION
   sed -i "" \
     "s/VERSION_NAME=.*/VERSION_NAME=$NEXT_VERSION/g" \
     gradle.properties
   git commit -am "Prepare next development version."
   git push
   gh pr create -f && gh pr merge --auto --squash

9. Draft a new release of A.B.C and publish it. Copy release notes added to CHANGELOG.md in step 1 into the release description.

Troubleshooting

• If the GitHub action fails, drop the artifacts from Sonatype and re-run the job. A Sonatype account with app.cash permissions is required. Raise an issue if you do not have this.
