Source generators are transitive?

[MihaMarkic]

Let's say I have Godot project with it's own source generators. Then I create a test project which references Godot project. And the thing is, that test project runs godot source generators as well even though they are not referenced explicitly.
How does one avoid that?

How is Godot shipping its source generator? If it's shipped in the same NuGet package of the library, then it will always be referenced.

[MihaMarkic]

Yeah, implicitly referenced by their SDK. Is there a way to exclude them from i.e. an unit test project? It's not a big deal, just that it's throwing a warning (and unnecessarily runs).
I'll check with authors to remove the warning, but is there a general way to remove generators in such case? Probably not, right?

[huoyaoyuan]

<PackageReference Include="SomePackage">
  <ExcludeAssets>analyzers</ExcludeAssets>
</PackageReference>

or Update="SomePackage" if the reference is set centrally from another file.

[MihaMarkic]

Cool, I'll definitely check this out. In meantime I've found a way to disable godot's source generators. I'd never guess that I'd need CompilerVisibleProperty, though.

I've tried like below (with both analyzers and generators) but it still runs generators.

<PackageReference Update="Godot.SourceGenerators" Version="4.5.1">
  <ExcludeAssets>generators</ExcludeAssets>
</PackageReference>

You need to exclude analyzers, not generators. Source generator is a kind of analyzer.

[Giorno-Giovanna-Dio]

Godot’s source generators are not referenced like a normal library.

•	Godot ships its generators via the SDK, not just as a normal PackageReference
•	SDK-provided analyzers/source generators are injected before project-level package filtering
•	Because of that:
•	ExcludeAssets=generators
•	ExcludeAssets=analyzers
•	even PrivateAssets=all

<PackageReference Update="Godot.SourceGenerators" Version="4.5.1"> <ExcludeAssets>generators</ExcludeAssets> </PackageReference>

This fails because:
1. Godot.SourceGenerators is pulled transitively by the Godot SDK
2. SDK analyzers are not filtered the same way as normal NuGet dependencies
3. The compiler sees them as implicitly referenced analyzers, not package assets

In your test project:
<PropertyGroup> <GodotDisableSourceGenerators>true</GodotDisableSourceGenerators> </PropertyGroup>

•	Godot explicitly checks this compiler-visible property
•	It short-circuits generator execution early

hope this helps

Yep, that's the solution I've found - except it also needs CompilerVisibleProperty node to work. And thanks for explaining why filtering does not work.
