I been spending some time today, trying to produce my first maven managed Google app engine 1.5.4 + GWT 2.4.0 build.
I'm finally at a stage where everything compiles, and the gae:run goal works. Which was more work that I had imagines, but hey, its all good fun.
Anyways, my question now is, eventhough everything works, I get the following ERROR when the datanucleus enhancer runs.
[ERROR] --------------------
[ERROR] Standard error from the DataNucleus tool + org.datanucleus.enhancer.DataNucleusEnhancer :

[ERROR] --------------------
What's going on there? What's with the [ERROR] blocks? It doesnt seem like there are any errors at all?
Additionally, I get the following warning, which I dont entirely understand
[WARNING] Could not transfer metadata asm:asm/maven-metadata.xml from/to local.repository (file:../../local.repository/trunk): No connector available to access repository local.repository (file:../../local.repository/trunk) of type legacy using the available factories WagonRepositoryConnectorFactory
And finally, how come all the dependencies are added to the datanucleus enchancer classpath? There's a [INFO] message from datanucleus enhancer listing all the jars in its classpath and it seem to contain everything, how come? I would have thought only the JDO and persistence related libraries was needed there?
I have same error as you. Then I changed version to latest one. The errors are gone.
