Question

I\'m having a problem setting up datanucleus enhancer to use with a google app engine project. If I use the datanucleus eclipse plugin everything goes well, but in my maven

Answer 1

I ran into the same issue while testing a maven gae plugin archetype.

I fixed it by adding exclusions in my gae runtime transitive dependencies

        
            net.kindleit
            gae-runtime
            ${gae.version}
            pom
            
                
                    com.google.appengine.orm
                    datanucleus-core
                

            
        

and then adding the nucleus core as a runtime dependency

            org.datanucleus
            datanucleus-core
            ${datanucleus-core.version}
            runtime
            
                
                    javax.transaction
                    transaction-api
                
            
        

as keeping the gae plugin section simple:

                org.datanucleus
                maven-datanucleus-plugin
                ${maven-datanucleus-plugin.version}
                
                    
                    **/model/*.class
                    true
                    ASM
                    JDO
                
                
                    
                        compile
                        
                            enhance
