Problems with Californium – is an unreleased version being used?

[matus-tomlein]

I have had problems building and running the project that are related to Californium.

1. In IDEServer and SemanticsServer, an object of the class CoapEndpoint is being created. When I tried to build the project it failed to find the class. I found out that it is actually called CoAPEndpoint in the current version of Californium so I renamed it in the 2 files and it worked.
2. When trying to run java -jar semantic-ide-1.0-SNAPSHOT.jar or java -jar reasoning-server-1.0-SNAPSHOT.jar I get the error:

Nov 10, 2015 10:29:45 AM org.eclipse.californium.core.network.config.NetworkConfig createStandardWithFile
INFO: Loading standard properties from file Californium.properties
Exception in thread "main" java.lang.NoSuchMethodError: org.eclipse.californium.elements.UDPConnector.setLogPackets(Z)V

    at ch.ethz.inf.vs.semantics.ide.IDEServer.main(IDEServer.java:22)

This makes me think that the project is using a different version of Californium that I was able to get.

I was unable to fix the second problem, is there a way I can do that?
