Initial commit was from Windows: lots of EOL trouble + differences in index.js.
Force pushed from a Linux checkout + rebuild (should solve most of the problems).

Building fails with

Errors:
* setup-dotnet.npm.@actions/http-client
filename: /home/runner/work/setup-dotnet/setup-dotnet/.licenses/npm/@actions/http-client.dep.yml
- cached dependency record not found
* setup-dotnet.npm.semver
filename: /home/runner/work/setup-dotnet/setup-dotnet/.licenses/npm/semver.dep.yml
- cached dependency record not found

I don't know how to fix that. My local licensed gives no errors. I guess it has to do with the specific GitHub build environment/actions that I don't have locally?

[dorssel]

http-client.dep.yml was split into 2 separate versions with the last merge on master: 1e92d49. Now licensed seems to expect a single version again.

I have no idea where semver.dep.yml comes from. I certainly did not add it.

[dorssel]

New info: it is the npm version. GitHub build environment has updated and now uses npm 8.1.2. This changes the behavior of licensed a lot, including adding the ones that are missing in my checks but also removing a few dozen others.

This means the current master probably will not even build itself. I don't think fixing this should be part of this pull request. Can you fix master so we can all rebase our failing pull requests on a new and working baseline?

This is also the problem with PR #250.

Hi @dorssel, the issue with license was fixed #258 , could you update your branch from main?

[dorssel]

@vsafonkin Done

Just ran into this issue in a new repo, any chance of getting this merged soon?

@xt0rted
This PR has been ready for merge for more than two months now. But I have no write access to this repo. And by now, there are merge conflicts which I cannot resolve, again due to missing write access. I have no clue how the workflow is for this project.

EDIT: I force-pushed after a rebase onto main. Should be mergable again.

.NET SDK 6.0.300 no longer allows comments in global.json either (although that may not be intended).
Nevertheless, this PR is stale. Not bothering to resolve merge conflicts (again...).
