something about jena : java.lang.NoClassDefFoundError: org/apache/jena/riot/lang/ReaderRIOTRDFXML
Stardog ships with support for Jena 3.2.0. It appears that this specific class was added in 3.3.0. You could try to force maven to use a more recent version, or use a different implementation of ReaderRIOT in your jena code. We will work on updating to the latest jena in a future release.
