I updated most libraries to newer versions. There are two blocking errors:
javax.jdo.JDOFatalInternalException: Class "com.google.appengine.datanucleus.DatastoreManager" was not found in the CLASSPATH
The class is in
datanucleus-core-5.2.2.jar
which is inWEB-INF/lib
and should therefore be on the classpath. 😕User-defined SCO wrapper class
org.datanucleus.store.types.sco.simple.xxxwas not found.
These classes have been moved to
org.datanucleus.store.types.wrappers.xxx
. The same goes fororg.datanucleus.store.types.backed.xxx
which are now atorg.datanucleus.store.types.wrappers.backed.xxx
. These are referenced inplugin.xml
indatanucleus-appengine
. This project is discontinued and built on Datanucleus 3.x 😢Note:
