Hello dbpedia-community!
I'm having troubles with mvn install of the DEF and I hope that someone
here can help me. If I don't comment out the Live Module from
extraction_framework's POM-File mvn install won't complete successfully.
That's what it complains about:

If I comment the live-module out, run the install successfully but
consequently running mvn scala:run in dump folder starts to download the
tables.sql but throws a new exception:

That's my config.properties located in dump-folder:

Since the description on dbpedia.org says just to run mvn install and
then the scala:run I don't know what could cause the problem. Also
googling for a specific error regarding the extraction_framework leads
to no results.
I'm working with Eclipse IDE installed the 3 required plugins and
downloaded the most recent revision from repository.
I hope you can help me set this thing up so I get the latest dumps. I'd
be most grateful :)
Regards,
David
P.S.: dumpDir=K:/Work/Eclipse Workspace/DBpedia_Dumps/to_update is where
my current "old" dumps are. Is it correct that every dump that is not
located there will not be updated but downloaded completely? It seems
that if the dumpDir is empty he throws a FileNotFound error so the
procedure is looking for dumps and trys to open something but shouldn't
it just conclude that there are no dumps to update and download them fresh?
