javax.persistence.PersistenceException: No Persistence provider for EntityManager named [message #463640]

I have JPA code in an Eclipse plugin project. When I launch the
application I get the following error message:

"javax.persistence.PersistenceException: No Persistence provider for
EntityManager named"

But if I extract all the JPA code including the
src/META-INF/persistence.xml into a separate eclipse project and JAR it
up and add it as dependency on my original project (via a plugin project
from jars) everything works fine.

While this is a workaround, it a huge inconvenience when the JPA code is
actively undergoing development and we need to JAR frequently.

I was wondering if any else has come across this issue and how it's been
solved.

Thanks for your time.
