war contents for WEB-INF/classes/META-INF/services are wrong after updating to grails-gradle-plugin 5.1.3

[gschueler]

Our app (https://github.com/rundeck/rundeck) uses grails 5.1.2, and we were upgrading to 5.1.4. We simultaneously attempted to update grails-gradle-plugin version from 5.1.1 to 5.1.3 and encountered an error:

The war file contents now are incorrect. Previously the /WEB-INF/classes/META-INF/services path contained the java service definitions. When building with grails-gradle-plugin 5.1.3, it seems the service definitions are instead placed in /META-INF/services/. Reverting to grails-gradle-plugin 5.1.2 seems to restore the correct behavior.

Using 5.1.3:

 jar tvf rundeckapp/build/libs/rundeck-4.0.0-SNAPSHOT.war  | grep META-INF/services
     0 Tue Mar 29 16:45:26 PDT 2022 META-INF/services/

     0 Tue Mar 29 16:44:00 PDT 2022 WEB-INF/classes/META-INF/services/

Reverting to 5.1.1 (or 5.1.2):
