some error of "mvn clean package"

[mdchr]

I installed with the command mvn clean package -Dlicense.skip=true as #41 gsingh93 said
although build success, there had some errors:

AND when I turn to use python-joern res = j.runGremlinQuery('getFunctionsByName("main")')
there is error:

File "", line 1, in
File "/usr/local/lib/python2.7/dist-packages/joern-0.1-py2.7.egg/joern/all.py", line 44, in runGremlinQuery
return self.gremlin.execute(finalQuery)
File "/usr/local/lib/python2.7/dist-packages/py2neo/ext/gremlin/init.py", line 36, in execute
response = self.resources["execute_script"].post({"script": script})
File "/usr/local/lib/python2.7/dist-packages/py2neo/core.py", line 288, in post
raise_from(self.error_class(message, **content), error)
File "/usr/local/lib/python2.7/dist-packages/py2neo/util.py", line 215, in raise_from
raise exception
py2neo.error.NoClassDefFoundError: javax/transaction/SystemException

I think this error related to the above mvn errors.

Can someone help me?

[jexp]

This plugin was built for an old version of Neo4j (2.1) and Tinkerpop (2).
No one has been using it in a long time.

You either have to use that old version of Neo4j

There is a new version TP3 that has a Gremlin Server backed by a newer gremlin-neo4j implementation as documented in the Tinkerpop manual.

to @jexp:
Thank you very much!
I have changed to Neo4j(2.1.5) and imported some .jar manually to solve this problem.
