The project is labeled with "Badly formed Maven project", see my pom.xml below. It builds fine though.
The source of the problem is the line "<extensions>true</extensions>". As soon as I comment it out or simply change the
value to "false", Netbeans pickes up the project OK. But the value must be "true" to build the project.
