Is there a known workaround for this? I’m getting the same issue under WSL 2.

As pointed out by @stephentoub, the issue can be solved by manually setting the LANG environment variable.

export LANG=en-US.UTF-8

Okay, this is funny, but I have nailed down the issue. It’s a bug in System.Text.RegularExpressions on WSL.

The applicaiton

using System;
using System.Text.RegularExpressions;

namespace ConsoleDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            string test = @"Parent/Child.Grand.Child";
            Regex reg = new Regex('^' + Regex.Escape(test) + '$', RegexOptions.IgnoreCase);

            Console.WriteLine("Test string: {0}", test);
            Console.WriteLine("Regex: {0}", reg);
            Console.WriteLine("Regex.IsMatch: {0}", reg.IsMatch(test));
        }
    }
}

Output on vanilla Ubuntu 18.04

Test string: Parent/Child.Grand.Child
Regex: ^Parent/Child\.Grand\.Child$
Regex.IsMatch: True

Output on WSL Ubuntu 18.04

Test string: Parent/Child.Grand.Child
Regex: ^Parent/Child\.Grand\.Child$
Regex.IsMatch: False

Removing RegexOptions.IgnoreCase option fixes the output on WSL as well.

Why this affects `dotnet pack`

NuGet is filtering files by the exclude parameter using Regex here:

Which results into file not found exceptions, since no files pass the regex filter.

Apart of fixing the regex issue, NuGet shall not throw FileNotFound exception if the file exists, but filtered out by the exclusions.

Since this is blocking a beta-release of ours, I decided to strip as much as possible to see if I could find a way around this. I’ve found it’s reproducible every time even on a new, empty project.

mkdir app1
cd app1
dotnet new console
dotnet pack

The env is still the same as post above.

A bit surprised such a basic thing passed acceptance tests, even though I know this is a preview? Is there any immediate plans to fix this?

We release our product as a set of packages and need to build native bits on Linux, so we are pretty blocked on this, or need to move built bits from Linux to Windows agents to do the packaging, which is of course something we would rather not want to spend time on.
