• System tests: https://confluent-open-source-kafka-system-test-results.s3-us-west-2.amazonaws.com/{dev_branch}/<BUILD_NUMBER>/report.html
  • Notable, this is hosted by Confluent.
    • If you, the RM, do not work for Confluent - contact someone from the company to set up the branch.
    • If you, the RM, do work for Confluent - set up the branch following the internal instructions in the wiki.

Create Release Artifacts

• For version < 4.0.0, Verify the LICENSE file by running python3 ./committer-tools/verify_license.py from the project root directory. In the future, this task may be automated (see 

  Jira
  server ASF JIRA serverId 5aa69414-a9e9-3523-82ec-879b028fb15b key KAFKA-12622

  ).This is done in the CI from 4.0.0
  
• Set environment variable `PUSH_REMOTE_NAME` to the remote you want to push to, e.g., export PUSH_REMOTE_NAME=origin (default is apache-github).
• Run the `release.py` script in the "release" folder of the kafka repository and follow the instructions. NOTE that if you are releasing a version prior to 1.0.x, you need to have minor edits on the script to change the three-digits pattern checking to four-digits pattern.
• This script will created a hidden directory called .release_work_dir. Don't delete this as you may need the contents later (for example the kafka-stream-x.x.x-test.jar)
• Troubleshooting:
  • If any step fails, make sure you have everything set up as described in the Prerequisites section and are using the correct passphrase for each config. When in doubt, remove or comment out anything in your settings that is not specifically needed for the release – for example, alternate profiles or unrelated servers, mirrors, etc in your `~/.m2/settings.xml` or `~/.gradle/gradle.properties`
  • Make sure you're running the script with Python3: sadly Python versions are not well managed especially on Macs, so you may want to explicitly invoke it with: python3 release.py 
  • Try setting an explicit path for both Java8 and Java17, rather than relying on your JAVA_HOME since this may be modified in the background by other applications (such as IDEs)
