Error with remote part depending on another remote part

[Alberto Mardegan]

The webapp-helper part defined in the wiki, as you can see from its definition [1], is meant to be built after the 'desktop-ubuntu-app-platform' part.

But when I run snapcraft on my project [2], all I get is an unhelpful red single line:
  'desktop-ubuntu-app-platform'
on the standard error. When run with --debug, I the stacktrace shows that somehow snapcraft has not added the 'desktop-ubuntu-app-platform' in its parts database:

I haven't tested it thoroughly, but this seems to be a workaround:

Another unexpected thing is that if I invert the order of the parts in the "after:" list, the build will fail.

[Sergio Schvezov (sergiusens)]

is this still a thing in the latest releases of snapcraft?
