How to mark a project to have problems?

Hello,

I'd like to mark a project to have problems if all of the following 
conditions are met:

1. There's a META-INF/persistence.xml file containing 
"org.datanucleus.api.jpa.PersistenceProviderImpl"

2. build.xml has not been modified to do the necessary enhancement steps.

So, how can I mark the project to have problems? And how can I change 
the build file, i.e. add the needed steps?

Kind regards
Peter
