Older version of Eclipse?

I've been interested in programming Minecraft plugins for a long time.

I have the following problem.

When I had the code for my plugin for the first time and exported it to my server, firstly there was no message that it was accepted and secondly the plugin was not functional because it did not work (heal command).

I have been working on a YT tutorial for a long time in which an older version of Eclipse (the program for programming).

I wanted to ask if you can download an older version of Eclipse somewhere?

Should be about
