Building examples not possible #142

Both examples (charging-server-simulator and guide) can't be built.
I didn't check the guide example. But CS' POM.xml is outdated:

Building Restcomm :: Examples :: charging-server-simulator 1.0.0-SNAPSHOT

The POM for org.mobicents.diameter:jdiameter-api:jar:1.7.0-SNAPSHOT is missing, no dependency information available
The POM for org.mobicents.diameter:jdiameter-impl:jar:1.7.0-SNAPSHOT is missing, no dependency information available
The POM for org.mobicents.diameter:restcomm-diameter-mux-jar:jar:1.7.0-SNAPSHOT is missing, no dependency information available

BUILD FAILURE

I've changed this to 1.7.1-160
Then I ran into that:
