No Check Annotation for compile error in C# project about setup-dotnet

[rainersigwald]

Configuring the compiler to emit absolute paths as here did not resolve the problem.

@ericsciple could you take a look? It looks to me like the regex should match this so I'm not totally sure why we're seeing this behavior.

@rainersigwald sorry i didnt see this issue before now.

The relative path not lining up makes sense. The runner attempts to root relative paths to the repo root, and if that path doesnt exist then the file property gets dropped.

iirc the runner sets an environment variable github=true, so defaulting to absolute when that is set, might be something to consider.

However, I am surprised that emitting absolute paths did not resolve the problem. As long as the path is under the repo root, that should work. Thanks for the links, i'll fork your repro and play around with it.

@ZEisinger looking at the matcher for v1, it looks like it should look something more like this:

"pattern": [
  {
    "regexp": "^\\s*([^:]+)\\((\\d+),(\\d+)\\): (error|warning) ([^:]+): (.*) \\[(.+)\\]$",
    "file": 1,
    "line": 2,
    "column": 3,
    "severity": 4,
    "code": 5,
    "message": 6,
    "fromPath": 7
  }
]

frompath will root the relative file

also i noticed location isnt a thing, so line/column instead

...although the annotation still didnt come out correct... debugging the runner now

[ericsciple]

@ZEisinger I opened a pr to fix fromPath in the runner. There is a bug in the runner where it currently does not trim the file name (csproj) before rooting the file. I'll sync w/ folks tomorrow to get a better idea when we can roll the fix out to prod.

You may not want to update the matcher configuration to include fromPath, until the runner fix is deployed.

[ericsciple]

The runner has rolled out everywhere now and the fromPath field can be used. Sorry for the delay we had a freeze for a while and was waiting for the new runner to roll out.

@ZEisinger i'm unable to assign a different assignee. The runner changes are in now.

I tested against this regex: https://regex101.com/r/MkisH3/4

@StanleyGoldman Thanks! I updated my test PR to use the latest master and everything looks good with and without configuring MSBuild to emit absolute paths.
