@rickeylev I patched this to our local environment and can confirm it works! |
When a package has extras, the requirements parsing discards the extra portion of the name and just returns the base name. When a repository is created for each entry, this means the same name is used for multiple repositories. Under WORKSPACE builds, duplicate repository names aren't an error. It appears the last defined repo takes affect. Under bzlmod, duplicate repo names are an error. To fix, mimic the last-defined-wins behavior in bzlmod by using a map to dedupe the package names. Fixes bazelbuild#1615

Requirements files are permitted to have duplicate lines for the same package. An example
of this is having separate lines for a package and its extras. When we parse requirements,
the parser discards the "extra" portion of the entry and returns a list of all the packages
as-is. When a repository is created for each entry, this means the same name is used for
multiple repositories.
Under WORKSPACE builds, duplicate repository names aren't an error. It appears that last
defined repo takes affect. Under bzlmod, duplicate repo names are an error.
To fix, mimic the last-defined-wins behavior in bzlmod by using a map to dedupe the package names.
Fixes #1615
