I have managed to load the broker from within Eclipse Scala IDE. I only needed to put server.properties and -Dlog4j.configuration in program arguments area.
How did you set up classpath? You need to set up classpath such that it can find all the jars necessary. And you shouldn’t have to remove any jar. For simplicity, could you r move everything and keep the jars which are only found under your KAFKA_HOME/libs folder? And try again.
