"componentAvailableTargetStatus: impossible;" on 3.10.1.0

same error as #8719 but the referenced fix should be in 3.10 from what I can tell

This occurs with a cabal build all --enable-benchmarks --enable-tests, and I think the repro is having a cabal.project file with a source-repository-package that duplicates a package in the packages: ... list. I'll circle back if I have time to put together a repro.

Thanks a lot. A repro would be great, especially if you can still reproduce this with master branch (or nightly at https://github.com/haskell/cabal/releases/tag/cabal-head).

I think the repro is having a cabal.project file with a source-repository-package that duplicates a package in the packages: ... list.

ya this seems to have been the case as it cropped up again during rebase and was fixed by deleting the source-repository-package entry.

I realised, I'm not sure it's a regression (nor if it's fixed on master), so let me modify the labels.
