Currently the buildpack will use whichever package manager it finds first, if the files of multiple package managers are found.
This occasionally results in support tickets where the user believes the build to not be installing dependencies correctly, when in fact they are adding dependencies to the wrong package manager file.
As such, we want to make the presence of multiple package manager files an error, but we're first adding a warning so it's not a surprise. (Plus with the recent Poetry support addition, there will be apps using the third party Poetry buildpack that have both a
poetry.lock
and the generatedrequirements.txt
until they remove the third-party buildpack.)Towards #1691.
