we are taken an example of isis demo application from your official website .
but when we are excuting in our environment then it gives error like Failed to execute goal org.datanucleus:maven-datanucleus-plugin:3.1.1:enhance (default) on project myapp-dom: Error executing DataNucleus tool org.datanucleus.enhancer.DataNucleusEnhancer: InvocationTargetException: Plugin (Bundle) "org.datanucleus" is already registered. Ensure you dont have multiple JAR versions of the same plugin in the classpath. The URL "file:/C:/Users/Web30India/.m2/repository/org/datanucleus/datanucleus-core/3.1.2/datanucleus-core-3.1.2.jar" is already registered, and you are trying to register an identical plugin located at URL "file:/C:/Users/Web30India/.m2/repository/org/datanucleus/datanucleus-core/3.1.5/datanucleus-core-3.1.5.jar." -> so please guide us. Waiting for your reply.. Thanking you.. Hiten Chauhan
