When launching the repositories example (using run.sh from target/dna-example-repositories-basic.dir/) I immediately get the following error:

Exception in thread "Thread-1" java.lang.NoSuchMethodError: org.apache.log4j.Logger.isTraceEnabled()Z
at org.slf4j.impl.Log4jLoggerAdapter.isTraceEnabled(Log4jLoggerAdapter.java:81)
at org.jboss.dna.common.util.Logger.isTraceEnabled(Logger.java:411)
at org.jboss.dna.graph.connector.map.MapRepositoryConnection.execute(MapRepositoryConnection.java
etc...

This is due to the lib direcotry containing both log4j-1.2.14.jar and log4j-1.2.8.jar. 1.2.14 is the correct one and contains the isTraceEnabled method, but version 1.2.8 is the one being used at runtime.

"mvn dependency:tree" shows the following dependendy paths to log4j:
