Warning: Specifying an absolute path to the project file is deprecated. Use

1178--project-dir to set the project's directory.

1179Config file path source is default config file.

1180Config file not found: /home/runner/.config/cabal/config

1181Writing default configuration to /home/runner/.config/cabal/config

1182Configuration is affected by the following files:

1183- cabal.project

1184Warning: The package list for 'hackage.haskell.org' does not exist. Run 'cabal

1185update' to download it.

1186Warning: There is no index-state for 'hackage.haskell.org' exactly at the

1187requested timestamp (2025-01-27T17:45:32Z). Also, there are no index-states

1188before the one requested, so the repository 'hackage.haskell.org' will be

1189empty.
