> This happens when for a dependency the scope is
> - set to 'provided' and
> - a parameter (in the case ${jbpm.version}) is used in the version field.
> So the relevant entry in the pom is:
> <dependency>
>       <groupId>org.drools</groupId>
>       <artifactId>drools-core</artifactId>
>       <version>${drools.version}</version>
>       <scope>provided</scope>
>     </dependency>
> which leads to
> 11:15:02,584  WARN Dependency artifact not found for: org.jbpm:jbpm-bpmn2:${jbpm.version}
> and then the NPE. I'm guessing the parameter is not being resolved.
> 1. it probably should resolve parameters
> 2. if a dependency is scoped as 'provided' I think it is supposed to locate it on the classpath and NOT from maven. However I'm not sure this is the way that works in testing anyway.
> 3. if the dependency  cannot be found it should probably stop and not even proceed rather then warn?
> 4. it should be interesting to see why it gets the NPE.
> If you change the dependency from 'provided' to 'test' things work fine.
