Error running test coverage when tests depend on internal lbraries.

[mihaimaruseac]

General summary/comments (optional)

Running stack test --coverage on a project with internal libraries where the test also depends on the internal library fails with Multiple files matching test-0.1.0.0-*.conf found in /tmp/internal-libs/b/.stack-work/dist/x86_64-linux-tinfo6/Cabal-2.0.1.0/package.conf.inplace/. Maybe try 'stack clean' on this package?

Steps to reproduce

1. Starting from this simple example run stack test --coverage.

Expected

The command should succeed and output should be similar to
