release/v5: create course fails to load plug-ins

[chucklorenz]

adapt create course "My Course" release/v5 installs the correct fw branch but errors while trying to install the required plug-ins:

Error: { '0': Error: adapt-contrib-vanilla "release/v5" is not a valid constraint

( However, adapt create course "My Course" issue/1987 succeeds, installing the required plug-ins.)

Tested on Windows 10, node v8.12.0 using git bash

@chucklorenz I think it might be more to do with how the plugins have been specified here than the fault of the CLI

[moloko]

I'm not sure the adapt cli has been set up to allow for plugins to be installed from a specific branch, only from tags or releases. If not then perhaps it should be, I can clearly see that it would be useful here!

[chucklorenz]

@moloko Yes, I'm sure you're correct. My work doesn't need this to be corrected--ended up downloading them manually. Not sure it's worth the time to update the adapt.json. Perhaps there is a value to others in this issue remaining visible until v5 is released? Your call when to close. Thanks!

[moloko]

Yes let's leave - possibly even convert to a feature request
