Carsten Ziegeler commented on FELIX-4192:
-----------------------------------------
Thanks for reporting, I just committed a potential fix to trunk, maybe you can
give it a try?
We changed the order in the generator and now validate after method signatures
are check, resulting in above problem. With my patch method signatures and
methods generation is skipped if no interface name is set. And this should then
fail during validation
> SCR Generator fails with a NPE in case a class level Reference doesn't define
> a referenceInterface

> Key: FELIX-4192
> URL: https://issues.apache.org/jira/browse/FELIX-4192
> Project: Felix
> Issue Type: Bug
> Components: Maven SCR Plugin
> Affects Versions: scr generator 1.8.0
> Environment: JDK7
> Reporter: Daniel Kuffner
> Assignee: Carsten Ziegeler
> Priority: Minor
> Fix For: scr generator 1.8.2
>
>
> Consider following simple component:
> {code}
> @Component
> @Reference(name="a", bind="setA", unbind="unsetA")
> public class MyJavaClass {
> }
> {code}
> the generator will fail with a NPE (see stacktrace). It would be preferable
> if the generator will fail with a usfull error message.
> Stacktrace:
> {code}
> java.lang.NullPointerException
