DataNucleus support for persistence to RDBMS Datastores. This plugin makes use of JDBC drivers for the datastores supported. Each supported datastore will have an associated "adapter" stored under org.datanucleus.store.rdbms.adapter, so if planning on supporting or improving support for a datastore this is the place to look (as well as in plugin.xml).
This project is built using Maven, by executing
mvn clean install which installs the built jar in your local Maven
