### Debugging Gradle

See the [Debugging Gradle](./contributing/Debugging.md) guide for tips on debugging Gradle.

If you made changes to build logic in the `build-logic` included build, you can run its tests by executing `./gradlew :build-logic:check`.

### Fixing DCO failures/Signing Off Commits After Submitting a Pull Request

To install, [Go](https://golang.org/dl/) must be installed. Once installed, execute this to install the binary:

```bash
