MSB3552: Resource file "**/*.resx" cannot be found when there is a long path

[msuddaby]

Describe the bug

Using dotnet run with the --no-cache argument produces the following error:

/usr/local/share/dotnet/sdk/10.0.100-rc.1.25451.107/Microsoft.Common.CurrentVersion.targets(3442,5): error MSB3552: Resource file "**/*.resx" cannot be found.

dotnet run runs fine without this argument.

matt@Mac ~ % dotnet run test.cs 
Hello!
matt@Mac ~ % dotnet run test.cs --no-cache
/usr/local/share/dotnet/sdk/10.0.100-rc.1.25451.107/Microsoft.Common.CurrentVersion.targets(3442,5): error MSB3552: Resource file "**/*.resx" cannot be found.

The build failed. Fix the build errors and run again.

matt@Mac ~ % ./test.cs 
Hello!
matt@Mac ~ % ./test.cs --no-cache
/usr/local/share/dotnet/sdk/10.0.100-rc.1.25451.107/Microsoft.Common.CurrentVersion.targets(3442,5): error MSB3552: Resource file "**/*.resx" cannot be found.

The build failed. Fix the build errors and run again.

To Reproduce

#!/usr/local/share/dotnet/dotnet run
Console.WriteLine("Hello!");
foreach (var arg in args) {
    Console.WriteLine(arg);
}

Exceptions (if any)

/usr/local/share/dotnet/sdk/10.0.100-rc.1.25451.107/Microsoft.Common.CurrentVersion.targets(3442,5): error MSB3552: Resource file "**/*.resx" cannot be found.

@msuddaby is this happening only for file-based apps (dotnet run file.cs) or project-based apps as well? It seems like an MSBuild issue, probably #3864 - do you have some backslashes somewhere in your file paths?

Just saw this error in the binlog, I guess that's the cause:

An exception occurred while expanding a fileSpec with globs: fileSpec: "**/*.resx", assuming it is a file name. Exception: System.AggregateException: One or more errors occurred.

(it appears only as a message, so I overlooked it previously)

Only file-based apps. I am able to build and run full projects from the command line just fine using dotnet run.

You might be having those projects in a different directory, hence not hitting that "long path" issue I described above (since file with the long path is not in that directory)?

Interesting! I was running the script originally from the top of my user directory /Users/matt/test.cs. Moving the script to a different folder /Users/matt/Scripts/test.cs works!

@jjonescz I'm concerned this is actually going to show up quite a bit with file-based apps as folks try to put them in locations above NPM apps, etc., that have really deep paths. We might need to think about if there's anything we can do to reduce the changes ppl hit this with file-based apps, or somehow improve the failure experience with a different message, suggesting enabling long paths in Windows, etc.

@maddymontaquila hit this today on our live stream after changing her folder name to be just 7 characters longer 🫨
