@sunix
I see the comment from @azatsarynnyy eclipse-che/che#19375 (comment)

Did you try to enable go modules in the devfile?

Also it would be nice (at least for testing goals):

• give more memory for Go component
• wait for Loading packages process - you can see the corresponding loader in the status bar when you open a go file after starting a workspace

@sunix
I quickly tested and looks like the code completion works with turned ON multi-root mode.
Also I don't have a lot of errors in the Problems view when the mode is ON.
To have it working I just did exactly what I mentioned in my previous comment above.

the multi-root mode is OFF

the multi-root mode is ON

But I have no experience with Go, so maybe I missed something...
