-------------------------------------
Resolution: Fixed
> Potential NPE if bind/unbind method can't be found during validation
> --------------------------------------------------------------------
>
> Key: FELIX-3917
> URL: https://issues.apache.org/jira/browse/FELIX-3917
> Project: Felix
> Issue Type: Bug
> Components: Maven SCR Plugin
> Affects Versions: maven-scr-plugin-1.10.0, scr ant task 1.4.0, scr generator 1.4.0
> Reporter: Carsten Ziegeler
> Assignee: Carsten Ziegeler
> Fix For: maven-scr-plugin-1.10.2, scr ant task 1.4.2, scr generator 1.4.2
>
>
> From the mailing list:
> I just updated to maven-scr-plugin:1.10.0 and org.apache.felix.scr.annotations:1.8.0 and I have this component:
> @Component(name = "org.example.component", immediate = true, policy = ConfigurationPolicy.IGNORE)
> public final class ContextRegistrator {
> @Reference
> HttpService httpService;
> }
> I didn't have the bind/unbind method but the plugin generated the names and put them into the Descriptor. The build was success but then it didn't work because SCR didn't find the non existing methods so I added the generateAccessors property to the plugin:
> <plugin>
> <groupId>org.apache.felix</groupId>
> <artifactId>maven-scr-plugin</artifactId>
> <version>1.10.0</version>
> <configuration>
> <generateAccessors>false</generateAccessors>
> </configuration>
> </plugin>
> When I build the project now it fails with this exception.
> Execution generate-scr-scrdescriptor of goal org.apache.felix:maven-scr-plugin:1.10.0:scr failed. NullPointerException -> [Help 1]
