"WARNING: couldn't find metadata for <pkg>" when using "license-report" command

[jtdaugherty]

I'm trying out cabal-plan's license-report command and I happened to notice this in the output:

WARNING: couldn't find metadata for mattermost-api-50200.14.0

The mattermost-api package is a direct dependency of the executable on which I am running license-report. Its source is located in a Git submodule of my source tree and the package is listed in cabal.project. Is there any way that I can ensure that cabal-plan will also include mattermost-api and its transitive dependencies in its license-report output?

Thanks!

Hi, I wanted to see if we could revive this ticket in case @hvr has any thoughts. I tried cabal-plan license-report again today on the latest release and I still see the above message, so I'd love to know if there's something I can do to resolve this. Thanks!
