Hi, firstly I have to say that the plugin is very useful. Unfortunately, I couldn't make it working. When I run the build task I obtain the following exception:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':com.mycompany.persistence.demo.provider:openjpaEnhance'.

Caused by: <openjpa-2.4.0-r422266:1674604 fatal user error> org.apache.openjpa.util.MetaDataException: MetaDataFactory could not be configured (conf.newMetaDataFactoryInstance() returned null). This might mean that no configuration properties were found. Ensure 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.

Here is my build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'at.schmutterer.oss.gradle:gradle-openjpa:0.2.0'
    }
}

apply plugin: 'openjpa'

openjpa {
        persistenceXmlFile = file('<full_path_to_my>/persistence.xml')

}

and here is my persistence.xml

            <!-- <property name="openjpa.MetaDataFactory" value="jpa"/> --> // it doesn't affect the build
        </properties>
    </persistence-unit>
</persistence>

@ChristophGr, @centic9 do you have any idea to get it working?

Thank you very much.

Cheers,

Luca
