The build process state also includes state that is tied to a particular Gradle user home directory.
When that directory changes between Gradle invocations, the state is discarded and recreated.
Typically, the Gradle user home directory does not change for a given process, so this is effectively process state.

## Develop and verify

After you make a change, you can run `mvn clean teamcity-configs:generate` to generate and verify the generated TeamCity configuration XMLs.

You also need to run `mvn clean verify` with Java 8 before committing changes.
