JPA 2 - "Maven in Netbeans rocks" continued

Last time I wanted to add JPA 2 to my existing maven project, I just clicked New -> Entity Class.
It not only helped me to create persistent.xml file, but it also added all necessary libraries to my pom as dependencies.

Maven support in Netbeans really surprised me

I had always been using M2Eclipse plugin for Eclipse to support maven projects. It is not so long ago when support for maven was absolutely missing in Netbeans. But nowdays Netbeans has great support for Maven projects. The biggest advantage of it is, that maven's pom.xml is enough definition of the project for Netbeans. So if you have maven project, you just open it in Netbeans. You don't have to import anything like it is in Eclipse. Dependency graph is still not as good as the M2Eclipse's one, but it's not so bad.
