Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: only one persistence provider can be packaged with an application [org.eclipse.persistence.jpa.PersistenceProvider, org.eclipse.persistence.jpa.PersistenceProvider]

........
........
Persistence.xml
<persistence-unit name="aglite-platform-persistence-unit" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
........
Though the provider is added As tried to add hibernate as a dependency and loaded the default provider. Then it tried to process the <provider> and failed with the above error.
Please suggest.
Regards
