> Key: FELIX-5464
> URL: https://issues.apache.org/jira/browse/FELIX-5464
> Project: Felix
> Issue Type: Bug
> Components: SCR Tooling
> Affects Versions: scr generator 1.15.0
> Environment: Jenkins 2.36
> Maven 3.3.9
> Java 1.7.0_79
> Reporter: Alexander Nöhrer
>
> I am encountering this problem on and off again only within our Jenkins build
> environment, I cannot reproduce it locally with the same java and maven
> version. Also after some code changes not related to SCR annotated classes it
> works again then it doesn't.
> Unfortunately I also was not able to produce a minimum example to reproduce
> this.
> Basically I guess what would already help, is to check against 'null' and log
> the 'pathToClassFile' that caused the input to be 'null'.
> By the way I wanted to do this myself just to get more information what is
> wrong in my environment, however the http://felix.apache.org/downloads.cgi
> links for the generator sources return 404...
> Here the output on Jenkins:
> [ERROR] Failed to execute goal org.apache.felix:maven-scr-plugin:1.23.0:scr
