How do I install Eclipse?
The main Eclipse application needs to be kept in the same folder as its support files otherwise it won't start. What I have done is to keep Eclipse in its own folder, somewhere out of the way, then right-click on the main Eclipse application and select "Make Alias". This will create a file called Eclipse alias. You can then move the alias to wherever you want it to be, without worrying about the rest of the Eclipse files. You can move this alias to the Applications folder, and then rename it back to Eclipse.
