Instructions for releasing bigtable-1.x

Install releasetool

See releasetool for installation instructions. You will need python 3.6+ to run this tool.

Prepare a release

  1. Make sure the team agrees that it is time to release.

  2. Run mvn clean on your branch.

  3. Run releasetool start. Select "minor" or "patch" for the release type. This will bump the artifact versions, ask you to edit release notes, and create the release pull request. You can either edit the release notes in your editor or wait until a PR is created on GitHub to edit there.

Note: be sure to make these notes nice as they will be used for the release notes as well.

Tag the release

  1. Run releasetool tag to publish a release on Github. It will list the last few merged PRs. Select the newly merged release PR. Releasetool will create the GitHub release with notes extracted from the pull request and tag the new release.

Pushing a release to Maven using Kokoro

  1. Trigger the java-bigtable-hbase/release/stage Kokoro job using the tag as the commitish (ie v.1.17.0) and wait for it to complete. This will stage the built artifacts and prepare them for publishing.

  2. Look through the logs for the java-bigtable-hbase/release/stage and find the staging repository ids used. It will look like comgooglecloudbigtable-1234.

  3. Optional Check https://oss.sonatype.org/ to see the staged release.

  4. Promote or drop the staged repository.

Be sure to again use the tag as the commitish (ie v.1.17.0)

a. To publish the staged repository, trigger the java-bigtable-hbase/release/promote Kokoro job for each staging repository. To specify the staging repository, add an environment variable configuration with STAGING_REPOSITORY_ID=<staging repository id> from the UI.

b. To drop (abort) the staged repository, trigger the java-bigtable-hbase/release/drop Kokoro job with the same staging repository id configuration as if you were publishing.

Prepare the next snapshot version

  1. Switch back to the branch you were releasing on (ie bigtable-1.x). Update your local branch (to merge in the version bump).

  2. Run releasetool start to bump the next snapshot version. Select "snapshot" when prompted for the release type. This will bump the artifact versions and create a pull request.

  3. Review and submit the PR.
