Re: [che-dev] "Hello World" issue for Che 7

[Dave Neary <dneary@xxxxxxxxxx>]

Hi,

Incidentally, I would never have arrived at your change from the error
message (the two changes: the project was missing a required "name"
field, and "mountsources" should have been "mountSources" - I'm not sure
if that is necessary in the main container also).

Is there anything in the devfile as it is now that I could take out
completely?

Thanks,
Dave.
