- [ ] Write unit tests that match behavioral changes, where the tests fail if the changes to the runtime are not applied.
  This may not always be possible but is a best-practice.
- [ ] Run `mvn verify` to make sure basic checks pass.
  A more thorough check will be performed on your pull request automatically.
- [ ] You have run the [Core IT][core-its] successfully.

Quick Build

- Run Maven, specifying a location into which the completed Maven distro should be installed:
    ```
    mvn -DdistributionTargetDir="$HOME/app/maven/apache-maven-4.1.x-SNAPSHOT" clean package
    ```
