[ERROR] Failed to execute goal org.apache.openjpa:openjpa-maven-plugin:3.0.0:enhance(enhanncer) on project x_base_core_project: Exception enhancer of goal org.apache.openjpa:openjpa-maven-plugin:3.0.0:enhance failed: MetaDataFactory could not be configured (conf.newMetaDataFactoryInstance() returned null). This might mean that no configuration properties were fount. Ensured that you have a META-INF/persistence.xml file, that it is available in your classpath, or that the properties file you are using for configuration is available. If you are using Ant, please see the <properties> or <propertiesFile> attributes of the task's nested <config> element. This can also occur if your OpenJPA distribution jars are corrupt, or if your security policy is overly strict.
