Questions tagged [uberjar]

An Uber JAR (AKA fat JAR or super JAR) is a JAR file that contains both the package and all its dependencies in one single JAR file. The advantage is that you can distribute an Uber JAR and not care at all whether or not dependencies are installed at the destination, as an Uber JAR actually has no dependencies.
