We want to provide alternative persistence.xml files to test alternative JPA providers in same project
persistence-eclipselink.xml and persiste-hibernate.xml will be created

Use Maven archetype JPA project  for start
http://www.mastertheboss.com/maven-hibernate-jpa/maven-and-jpa-tutorial


Create project from archetype

[dave@dave workspace]$ mvn archetype:generate -DarchetypeGroupId=com.github.lalyos -DarchetypeArtifactId=standalone-jpa-eclipselink-archetype -DgroupId=com.mastertheboss -DartifactId=EclipseJPAExample -Dversion=1.0-SNAPSHOT -Dpackage=com.mastertheboss -DinteractiveMode=false
