Eclipse Runtime Binary – the bare eclipse IDE install
I finally found where I can download a bare eclipse IDE. It’s called “Platform Runtime Binary”.
choose a release, scroll to the Platform Runtime Binary,
and happily download.
However, this package seems to not be provided any more. And taking a bare eclipse and only installing what you need is a good approach anyway.
To install the additional packages just Help -> Install Additional Software and add
Eclipse Juno - http://download.eclipse.org/releases/juno. This should provide you with the main release modules.
Thanks to the post (which is now outdated) that got me the name and hint of hidden downloads.
