Trouble with vsCode plugin build

Hi,

I'm moving to vscode and have the plugin installed and have run the Monkey C: verify installation, and it prompted for my developer key and says everything is ok.  When I try to right click and run 'Build Current Project' I get:

Connect IQ project not found. Be sure your project has a monkey.jungle file and the project's Jungle Files setting is correct.

This happens if I click on the containing folder or the monkey.jungle file, or type the command into the ctrl+shift+p box.  I'm not sure what I need to do to get it to recognise the project. This is an existing project which works in Eclipse.

Anyone have this problem and fixed it?

Thanks
