mvn compile doesn't work (unless you have already run install). Compile creates the class files but does not create jars. Since we have a multi module project the other modules depend on jars for previous modules being available. To satisfy this you have a couple of options:
First Option: mvn package -DskipTests This works because package produces jars for every module. Thus when something like hbase-server needs a module that was built before the jar is available in the target folder. Second Option: mvn install -DskipTests The jars for all modules in the project will be in your local maven repo. Now if a mvn compile runs and tries to resolve dependencies maven will look in your local repo and find the jars that were created. I'm not as fond of this option because it's tough to remember what jar you last put into the local maven repo.
