Is there an Eclipse plugin for collaborative editing? [closed]

I setup etherpad and showed my co-worker, and he swears there is an Eclipse plugin that does the same thing but can not remember the name. Neither of us use Eclipse regularly except if we were both interested in making the switch.

Does Eclipse have collaboration?

Saros is a real-time collaborative editor for eclipse projects. All collaborators have an identical copy of Eclipse projects. Two or more users can jointly edit files in the project.

Does Eclipse have live share?

CodeTogether is a plugin that lets you live share Eclipse. Host a session from your Eclipse IDE and invite anyone to join—they can join from Eclipse, IntelliJ, VS Code, or even a browser.

Where are Eclipse plugins located?

One way of finding out is to select Help > About Eclipse Platform >. From this dialog, click Plug-in Details to get a list of all installed plug-ins, along with vendor and version information.
