[jira] [Created] (OPENJPA-2424) Classes are enhanced multiple times in a multi persistence-unit project

Sebastian Laag created OPENJPA-2424:
---------------------------------------

             Summary: Classes are enhanced multiple times in a multi persistence-unit project
                 Key: OPENJPA-2424
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2424
             Project: OpenJPA
          Issue Type: Bug
          Components: Enhance
    Affects Versions: 2.2.2
         Environment: Windows 7
JDK 1.7
Maven 3.0.5
            Reporter: Sebastian Laag


We use the above environment to build our project. We use the openjpa-maven-plugin for the enhancement of the JPA classes. The persistence.xml configures 4 persistence-units for different database connections. Every persistence-unit defines own classes and uses the exclude-unlisted-classes Tag, because we only want every class to be enhanced only once.

Now if we execute mvn install every defined class will be enhanced 4 times. The persistence.xml looks like this.

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
    http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
	version="2.0">
	<persistence-unit name="db1">
		<class>ClassA</class>

		<exclude-unlisted-classes>true</exclude-unlisted-classes>

		<properties>
                      ...some properties for the connection...
		</properties>
	</persistence-unit>

	<persistence-unit name="db2">
		<class>ClassB</class>

		<exclude-unlisted-classes>true</exclude-unlisted-classes>

		<properties>
                      ...some properties for the connection...
		</properties>
	</persistence-unit>

	<persistence-unit name="db3">
		<class>ClassC</class>

		<exclude-unlisted-classes>true</exclude-unlisted-classes>

		<properties>
                      ...some properties for the connection...
		</properties>
	</persistence-unit>


	<persistence-unit name="db4">
		<class>ClassD</class>

		<exclude-unlisted-classes>true</exclude-unlisted-classes>

		<properties>
                      ...some properties for the connection...
		</properties>
	</persistence-unit>
</persistence>
