Cannot Install Aptana plugin on Eclipse 4.2

Question

I\'ve installed Eclipse 4.2 Juno. Now I want to install aptana for developing ruby, but I get the following error,

Unable to read repository at http://dow

Answer 1

As of 01/29/18 and Eclipse Photon, none of the URLs listed as answers here work in Eclipse's built-in software sources panel. However, after some trial and error mashing up Aptana's old download URLs with the ones Appcelerator (which bought Aptana in 2015) uses for its own software, I got:

http://download.appcelerator.com/aptana/studio3/plugin/update/stable

This works, is totally plug-and-play, and is obviously official - no need to go off to some shady 3rd party hosting site. I just wish someone at Appcelerator had spent 15 minutes to post it somewhere.
