Update to UIMA 3 and DKpro Core to Version 2.1.0

[pagelj]

Several issues occurred:

• PARAM_OVERWRITE = true needs to be added to all calls of XmiWriter
• Import of the POS libraries needs to changed (e.g. POS_NOUN instead of NN)
• stanfordnlp API is now called corenlp
• Unresolved issue with DocumentMetaData
• Some libraries are now under org.dkpo. instead of de.tudarmstadt.ukp.dkpro. (but not all!)
• commons-lang needs to be updated to commons-lang3
• dkpro functions that return annotations now return List instead of Collection

For the DocumentMetaData issue, also see https://groups.google.com/forum/#!msg/dkpro-core-user/-DtO5Ivnk9I/o5ZpB9v7BwAJ and https://issues.apache.org/jira/browse/UIMA-5054
Unfortunately, UIMA Java SDK >=2.8.1 does not solve the problem for us. Either it did not actually get fixed or our issue is a different one

Postponing this issue for now

dkpro is now at 1.10.0 anyway ...

[pagelj]

true, I also tried to update to 1.10.0, but the issue still persists

[nilsreiter]

It’s 1.12.0 by now 😉

Updating to UIMA 3 would also be entailed by this, and that probably has other benefits.

Https://github.com/nilsreiter/CorefAnnotator/issues/300 would also benefit from that.

Ok, I will give it another try
