ILMerge version not found while building VMR main

[tmds]

I'm building vmr main (at 2e71a23ab11c8480aa28ad959656dceb4020760c).

The build fails with:

  /home/tmds/repos/dotnet/src/nuget-client/src/NuGet.Core/NuGet.Build.Tasks.Pack/NuGet.Build.Tasks.Pack.csproj : error NU1102: Unable to find package ILMerge with version (>= 3.0.41) [/home/tmds/repos/dotnet/src/nuget-client/build/restorehelper.targets]

Is it expected for the main branch to not be buildable? And what can I do about it?

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

This prebuilt comes from NuGet.Client and is tracked with NuGet/Home#12604. The prebuilts tarball was update in dotnet/installer#16448 to include this but it looks like an updated dependency version flowed in.

@NikolaMilosavljevic - If you are not close to a solution, could you update the prebuilts tarball? TIA.

I'll update the tarball, to unblock the VMR build.

How do you obtain the ILMerge package? and create a new tarball?

[tmds]

I ran the ./build.sh command without the --online argument. Would adding the argument have made a difference?

Yes, --online would have enabled the build to obtain packages from nuget.org and show them as warnings in your build, instead of errors.

Yes, the build will pass with an online build. You can also retrieve the package from the online build to update the tarball.

[tmds]

Is it the expectation that the main branch is (occasionally) not working without the --online flag?
Or is the expected workflow to update the prebuilts (in sync) as part of updating the main branch?

[MichaelSimons]

Is it the expectation that the main branch is (occasionally) not working without the --online flag?

Yes, until we complete the work to enable prebuilt detection at the repo level.

[tmds]

Thanks for clarifying.

This was fixed by NuGet.Client in NuGet/NuGet.Client#5178. We added a patch until the fix flows in.
