If you're trying to install uberSVN on a fresh install of Mountain Lion (or an upgrade from Lion) you may get an error saying that you need Java in order to continue. The reason for this is that Apple stopped including it's Java Runtime Environment (JRE) with the release of Lion. In order to use web pages or applications that use Java, including uberSVN, you'll need to install Java 1.6. To do this: - Open a terminal window and type "java - version" . -- OS X will then notice that Java is not installed and give you an option to download it - Java 1.6 will be automatically installed once the download is finished. --You can check that the install was successful by typing "java -version" again in the terminal window. Once this is complete run the uberSVN installer again and it will complete successfully. We'll get this in the official documentation shortly, and are looking at options to resolve this on the product side.
