Hey,
Could you please expand a bit more on what issue you see with emmet, is it not expanding or any other, any example you can point to or how you are trying to use Emmet. It will be awesome if you could do the same regarding the bootstrap helper also what do you mean with bootstrap helper?
Now regarding Eclipse, I’ve also seen the issue and on my side, you could add Antimalware Service Executable to Windows Defender’s exclusion list, point the exclusion list to the directory where you have your Eclipse and also to the ~/.codemix directory then restart your system. Are you running on windows?
Best Regards
Ignacio
