Below is a step-by-step list of instructions that takes you through the process of setting up an Eclipse environment for building the Groovy-Eclipse plugin. These instructions were written while going through the process on a Mac OS Lion machine. See here for a similar set of instructions on Ubuntu 10.04. Except for installing The choosing an Eclipse and installing git, the process is similar no matter which OS and architecture you are using
These instructions are meant for Eclipse 3.7 (Indigo) or Eclipse 4.2 (Juno).
Download and Install Eclipse
Download and unzip Eclipse for RCP/Plug-in Developers from http://eclipse.org/downloads. Choose the appropriate version for your architecture.
Ubuntu note: Don't install Eclipse from the Ubuntu repositories download it manually from eclipse.org instead.
Groovy-Eclipse is available from github. To work with github, you need to have git installed on your machine. Github has some good documentation for a gentle introduction into git and it explains how to install the command line tools.
Preferably, the latest version of Groovy Eclipse should be installed, which can be obtained from the update site for the latest snapshot:
Checkout Source from git
