My problem is that i am working on some code for Tika-parsers 1.1-SNAPSHOT
that i need to use in Nutch. However, when i build tika-parsers and put it in
Nutch' lib directory i still seem to be missing dependencies. Then trouble
begins:
Exception in thread "main" java.lang.NoClassDefFoundError: Could not

Nick told me to remove DWG from the org.apache.tika.parsers.Parsers config
file, which i did. But then other dependency issues come and go. The more
parsers i remove from the config file the better it goes, but then Tika won't
build anymore because of failing tests.
I asked this on the Nutch list because i wasn't sure anymore how Nutch deals
with these its own deps, which you explained well.
I'll give up for now :)
