The version used in the Maven projects needs to be set by hand in the following files: - maven/pom.xml - apps/beeswax/java/pom.xml - desktop/libs/hadoop/java/pom.xml - desktop/libs/hadoop/static-group-mapping/pom.xml - desktop/libs/hadoop/sudo-shell/pom.xml In the case of maven/pom.xml, change the first tag. In the other cases, change the tag within the tag. In addition, when running a release, all of these will need to be changed to remove "-SNAPSHOT". This will eventually be automated via the Maven release plugin, but is by hand for the moment. For release builds, you will also need to change MAVEN_VERSION in Makefile.vars to not include "-SNAPSHOT".
