Eclipse CDT is not available in a form which can be easily consumed by maven or gradle. To fix this, we publish Eclipse's formatter and all its dependencies, along with a small amount of glue code, into the com.diffplug.gradle.spotless:spotless-eclipse-cdt artifact.
To publish a new version, update the _ext/eclipse-cdt/gradle.properties appropriately and see CONTRIBUTING.md how to enable
_ext projects.
Spotless at large is under the Apache 2.0 license, but this jar is under the EPL v1.
