@aragot , I’ve recently found that all these new API services can be easily loaded via the ScriptRunner @PluginModule annotation, making usage a little easier.
@PluginModule
ContentService contentService
for example, however you must using the Expansions on the find else Groovy’s proxy class loader goes haywire. Unfortunately the REST API documentation doesn’t give comprehensive information on expansion options; some Services contain a static default set, but it appears for the majority, it’s a voyage of discovery on the REST API version first…
Your note on how to use the compound Expansions is very useful - I’d not noted the Expansions class in the Javadoc.
