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”.
Open http://download.eclipse.org/eclipse/downloads/
choose a release, scroll to the Platform Runtime Binary,
and happily download.
A bare eclipse IDE is useful if none of the prepared packages from eclipse.org/downloads really fits your needs. For non-Java web development for example with their last major release they provided a package for JavaScript development. You could then extend that for PHP.
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Thanks to the post (which is now outdated) that got me the name and hint of hidden downloads.
