Eclipse is not our favorite IDE, but it's probably the most popular for Open Source development, especially in Java. It's got a ton of plugins, and is essential for Android development.

1. Download the latest Eclipse IDE for Java Developers package for 64-bit Mac OS X.
   • Download from http://www.eclipse.org/downloads/.
   • Starting with Java lets us start (relatively) small and add only the plugins we need.
     • We could (used to) start with the Classic package, but that's been hidden away on another page.
2. Double-click on the downloaded tarball to unpack it.
3. Rename the unpacked eclipse directory as Eclipse/4.3 (or whatever the corresponding version number is).
4. Move the Eclipse/4.3 directory into Applications.
5. Drag Eclipse.app from the Eclipse/4.3 directory into the dock.
6. Start Eclipse.
7. When prompted for a workspace, select ~/Work/Eclipse Workspace.
   • Check the box to set this as the default workspace.

NOTE: If you've got Gatekeeper set to its default strictness level ("Mac Store and identified developers") then the first time you run Eclipse, you'll need to right-click and choose Open, instead of clicking directly on the icon. This will let you override the Gatekeeper setting.

Eclipse has a ton of plugins available. Even most of the core functionality is actually implemented as plugins.
