What dependencies are required for DataNucleus 3.0.0-release?

I'm trying to use datanucleus as JPA provider for GAE. This is my pom.xml (part of it):

<dependency>
  <groupId>org.apache.geronimo.specs</groupId>
  <artifactId>geronimo-jpa_2.0_spec</artifactId>
  <version>1.1</version>
</dependency>
<dependency>
  <groupId>org.apache.geronimo.specs</groupId>
  <artifactId>geronimo-jta_1.1_spec</artifactId>
  <version>1.1.1</version> 
</dependency>
<dependency>
  <groupId>org.datanucleus</groupId>
  <artifactId>datanucleus-api-jpa</artifactId>
  <version>3.0.0-release</version>
</dependency>
<dependency>
  <groupId>org.datanucleus</groupId>
  <artifactId>datanucleus-core</artifactId>
  <version>3.0.0-release</version>
</dependency>
<dependency>
  <groupId>org.datanucleus</groupId>
  <artifactId>datanucleus-rdbms</artifactId>
  <version>3.0.0-release</version>
</dependency>
<dependency>
  <groupId>com.google.appengine.orm</groupId>
  <artifactId>datanucleus-appengine</artifactId>
  <version>1.0.8</version>
</dependency>

Class finding exception is thrown in runtime:

java.lang.NoClassDefFoundError: org/datanucleus/jpa/exceptions/NoPersistenceXmlException
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389)
at java.lang.Class.getConstructor0(Class.java:2699)
at java.lang.Class.newInstance0(Class.java:326)
at java.lang.Class.newInstance(Class.java:308)
at org.apache.geronimo.osgi.locator.ProviderLocator.getServices(ProviderLocator.java:319)
at javax.persistence.spi.PersistenceProviderResolverHolder$DefaultPersistenceProviderResolver.getPersistenceProviders(PersistenceProviderResolverHolder.java:108)
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:91)
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:72)
...

Where this org.datanucleus.jpa.exceptions.NoPersistenceXmlException class is located? What JAR did I miss?

Official Link For Maven

would provide the required info. If not, do mention here as @DataNucleus can update the website in such an event.

This is how it works (it's datanucleus 1.x, which is the highest version that works with GAE):

    <dependency>
        <groupId>org.apache.geronimo.specs</groupId>
        <artifactId>geronimo-jpa_3.0_spec</artifactId>
        <version>1.1.1</version>
    </dependency>
    <dependency>
        <groupId>org.datanucleus</groupId>
        <artifactId>datanucleus-jpa</artifactId>
        <version>1.1.5</version>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>org.datanucleus</groupId>
        <artifactId>datanucleus-core</artifactId>
        <version>1.1.5</version>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>org.datanucleus</groupId>
        <artifactId>datanucleus-rdbms</artifactId>
        <version>1.1.5</version>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>javax.jdo</groupId>
        <artifactId>jdo-api</artifactId>
        <version>3.0</version>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>com.google.appengine.orm</groupId>
        <artifactId>datanucleus-appengine</artifactId>
        <version>1.0.8</version>
        <scope>runtime</scope>
    </dependency>

Do you need 

<dependency>
  <groupId>org.datanucleus</groupId>
  <artifactId>datanucleus-jpa</artifactId>
  <version>2.1.8</version>
</dependency>

Source

Also, note that it has
geronimo-jpa_2.0_spec
datanucleus-core
geronimo-validation_1.0_spec
