My Eclipse configuration - OS X

Starting to discover OS X, I wanted to set up an Eclipse environment similar to the one I use under Linux. As I'm far from being proficient in OS X, probability is high that steps reported here are not optimum ones. But they work  So, let's go:

• Java:
• start a terminal, and type java. Accept java installation. Installed version is 1.6.0.

• Eclipse:
• download Juno for Mac OS X (Eclipse IDE for Java developers - 64 bits version for me)
• move eclipse folder to Applications folder
• drag the Eclipse icon to the dock
• WindowBuilder:
• install it as described in this article
• after installation of Eclipse SDK, the list of update sites is empty! To re-populate it: copy back eclipse folder to a user folder, start eclipse, export update sites, go back to installed eclipse, import update sites
• Subversive:
• Subversion is already installed (tested from a terminal). Does it come from iOS SDK installation, or is it installed by default? I don't know...
• install subversive and connector in a way similar to the one presented in this article
• Android:
• download the SDK Tools for Mac.
• unpack the downloaded zip file. Move resulting directory to a Development directory, in my home directory.
• install the Eclipse ADT plugin. Configure Eclipse with directory of SDK tools.
• install Android platform tools and one version of the SDK at least.
