che: A vsx that works fine on Gitpod and VS Code but does NOT on Che

Hello,

i’m currently running a minikube cluster with che server on it. My goal is to add a VS extension to it. I followed this tutorial on how to add a VS extension to a custom plug-in registry: https://www.eclipse.org/che/docs/che-7/building-and-running-a-custom-registry-image/#building-a-custom-devfile-registry_building-and-running-a-custom-registry-image I’m stuck at step 5. Running docker build -t my-devfile-registry gives me the following output: PS C:\repositories\che-plugin-registry> docker build -t che-plugin-registry
"docker build" requires exactly 1 argument. I’ve tried running .build.sh file from powershell, but it briefly opens a window and closes it, without any result. I’ve tried adding this folder in Plug-in view in Che Editor, but it didn’t add anything new.

My question is, what am i missing?
