I tried to build Eclipse for the Pi4. Horrendous. Eclipse, despite me using it since very early version and being a fan, has become too big and bloated for normal humans to build and I have moved to alternatives. Even Debian are thinking of removing it entirely from their repo due to the difficulties in building recent versions.
I did get VSCode working, and have now moved to that on my main PC as well, throwing Eclipse out.
