I get this error:

[ERROR] Exception in thread "main" Plugin (Bundle) "org.datanucleus" is already registered. Ensure you dont have multiple JAR versions of the same plugin in the classpath.

I had it too and got it fixed by doing that

    <dependency>
        <groupId>org.datanucleus</groupId>
        <artifactId>datanucleus-accessplatform-jdo-rdbms</artifactId>
        <version>4.1.0-m1</version>
        <!-- <version>3.3.0-release</version> -->
        <type>pom</type>
    </dependency>

Now I got another problem and I'm not sure if this solution was the best one.
