I have been using Code-OSS in manjaro linux for some months now and this is the first time I am encountering this. (After I reinstalled manjaro) When I search for e.g, Java Extension Pack or Intellisense I don't get any result in the extension marketplace. I don't know if it's the problem of my setup or everyone is experiencing this. If you know of a solution please tell me.
Thanks in advance
Thank you @Clay for responding. I saw that post prior to me posting this question. Those bits of json code were already in my product.json file but still I was not able to get the extensions. Then I built the VISUAL STUDIO CODE (visual-studio-code-bin) from AUR and now its working normally as expected. I don't know what's the reason behind this,but that's how I fixed it.
Also if someone is reading this and wanna know about the different variants of VSCode then here is the archWiki page for VSCode.
