Hi Mosur, I too am useless without emacs. Might as well
put winter gloves on my hand with Microsoft, or Google
bindings.
I use Emacs+ every day. I think your issue might be the
Eclipse version. Emacs+ was made unusable at some point
when Eclipse changed some of its inner workings. For several
Eclipse releases Emacs+ was therefore unavailable.
I use Eclipse 2020-09, and Emacs+ works fine. The last few
versions of Eclipse have also worked. I don't *think* the Eclipse
flavor makes a difference. I tend to use the one that leans towards
Javascript development, though I develop in Python almost
exclusively.
