NuGet Publisher fails with 409 due to publishing symbols packages twice

When using the NuGet Publisher task with a wildcard pattern of *__.nupkg, the step inevitably fails when symbols packages are present. For example, if I have these packages:

bin\my.1.0.nupkg
bin\my.1.0.symbols.nupkg

This task will find both files and try to publish them both. But nuget.exe push will automatically push the symbols package when you push bin\my.1.0.nupkg so when this task then tries to push the symbols package itself, a 409 inevitably results.

I workaround this by using this search pattern instead of the default: **\*.nupkg;-:**\*.symbols.nupkg but it would be nice if the task was smart enough to suppress symbol packages from being uploaded twice.

Your workaround is the correct way to achieve what you want.

At some point, NuGet will probably change how symbols packages work. Per their design that a package is uniquely identified by id + version, it’s pretty broken that the client emits two packages with the same id + version but different contents.

what am I doing wrong? I’m using a dot net push task step in my Azure CI pipe and am getting this 409 error. I see this git issue is closed as if it’s all good, but I don’t think so.
