How to use static metamodel from dependency project/library? [message #1791410] Fri, 29 June 2018 00:01 Go to next message

I'm trying to use in a new project (Jax-ws/SOAP) another project as dependency (a "backend" where are all entities, persistence.xml and StaticMetamodel), but I cant use any method (defined in the backend) that uses Metamodel, they throw NPE

What do I have to do to make the 2nd project recognize/generate the metamodels? or the modifications must be done in the backend project?

I'm using eclipselink 2.6.1

backend POM project is very simple:
<modelVersion>4.0.0</modelVersion>
    <groupId>org</groupId>
    <artifactId>SAOS-backend</artifactId>
    <version>1</version>
    <packaging>jar</packaging>
<dependencies>
            <dependency>
                <groupId>org.eclipse.persistence</groupId>
                <artifactId>eclipselink</artifactId>
                <version>2.6.1</version>
            </dependency>
            <dependency>
                <groupId>org.eclipse.persistence</groupId>
                <artifactId>org.eclipse.persistence.jpa.modelgen.processor</artifactId>
                <version>2.6.1</version>
            </dependency>
    ....
    ...

update: the problem persists but not like we thought, there are some metamodels that doesn't throw NPE, can be used in criteria or JPQL but some of them doesn't work.
How is this possible?
The same happens trying to use Metas in JUnit test
