   You can also install the https://github.com/spring-io/spring-javaformat/#intellij-idea[Spring JavaFormat IntelliJ Plugin] or format the code from the Gradle build by running `./gradlew format`.
   Note that if you have format violations in `buildSrc`, you can fix them by running `./gradlew -p buildSrc format` from the project root directory.
 * The build includes Checkstyle rules for many of our code conventions. Run `./gradlew checkstyleMain checkstyleTest` if you want to check your changes are compliant.
