Update 14/Aug/2018: I no longer maintain the package mentioned and the download links below are most likely broken.
I uploaded a lightweight Eclipse package (based on Helios 3.6.1) for web development (includes Maven, SVN and basic Spring integration, JEE / web tools plugins, but no Mylyn or other non-essential stuff) … This is currently only for Windows. It requires a JDK and is completely free / open source software.
See the txt file for quick installation steps.
