The name `AssemblyCommitIds` does not exist in the current context.

[m-rienstra]

When I try to compile the new LibGit2Sharp (retrieved from GitHub) I get the error:
The name AssemblyCommitIds does not exist in the current context.
Trying to compile it using Visual Studio 2017 (Community Edition), the reason for compilation is that I'm trying to create a custom Git "EditorWindow" for Unity 2017.3b.
Thanks in advance!

I just realized that it might be useful to know that the error occurs in Version.cs and is caused by 2 string properties:

Line 40

public virtual string LibGit2CommitSha => RetrieveAbbrevShaFrom(AssemblyCommitIds.LibGit2CommitSha);

Line 45

public virtual string LibGit2SharpCommitSha => RetrieveAbbrevShaFrom(AssemblyCommitIds.LibGit2SharpCommitSha);

Out of curiosity, does it work if you run dotnet build on the command line?

[m-rienstra]

That gives the same output, the issue is that AssemblyCommitIds is not present in any of the scripts.

@m-rienstra AssemblyCommitIds is a class generated by MSBuild targets: https://github.com/libgit2/libgit2sharp/blob/master/LibGit2Sharp/CodeGenerator.targets#L80

How did you get the copy of the code you're trying to build? Did you check it out via git?

[m-rienstra]

I used git to clone the repository to a local drive, then I used visual studio to open it and tried to build it

If you look in the LibGit2Sharp obj folder, do you see an AssemblyCommitIds.g.cs file in there? What about NativeDllName.g.cs or UniqueIdentifier.g.cs?

[m-rienstra]

This is what I have in the folder:

There's no AssemblyCommitIds.g.cs

@m-rienstra The only reason I can think of that might cause that to happen would be if you were building the code from outside of a cloned copy, meaning you don't have a .git folder.

Can you install http://msbuildlog.com/ and build the solution with that and then attach copy of the log file to the issue ? That might help me understand better why the target apparently isn't running.

@bording Here's the error log

@m-rienstra Looking at the log file, it appears that my original suspicion is correct. The reason you're seeing the error is that the GitCommitId property is not being set by the Nerdbank,GitVersioning's GetBuildVersion target.

I was just able to reproduce this by deleting my .git folder, making my copy of the code not be a git repository.

Looking at the log, I see your code is in the following path: C:\Users\markr\Documents\Workspace\External\libgit2sharp-master

If you look in that folder, I suspect you'll find that you don't have a .git folder, meaning that isn't actually a git repo.

@m-rienstra FYI, I've just added a change to #1511 that will let the GenerateAssemblyCommitIdsCs target handle the scenario of trying to build the project when not in a git repo.

If you don't want to wait for that to be merged, you could try checking out that branch and see how that works for you.

Fixed via #1511
