 ### eclipse groovy
 
-[homepage](https://github.com/groovy/groovy-eclipse/wiki). [changelog](https://github.com/groovy/groovy-eclipse/releases). [compatible versions](https://github.com/diffplug/spotless/tree/main/lib-extra/src/main/resources/com/diffplug/spotless/extra/groovy_eclipse_formatter). The Groovy formatter uses some of the [eclipse jdt](#eclipse-jdt) configuration parameters in addition to groovy-specific ones. All parameters can be configured within a single file, like the Java properties file [greclipse.properties](../testlib/src/main/resources/groovy/greclipse/format/greclipse.properties) in the previous example. The formatter step can also load the [exported Eclipse properties](../ECLIPSE_SCREENSHOTS.md) and augment it with the `.metadata/.plugins/org.eclipse.core.runtime/.settings/org.codehaus.groovy.eclipse.ui.prefs` from your Eclipse workspace as shown below.
