AutoGenerateBuilder for type doesn't generate classess

[jvmlet]

If more than 1 AutoGenerateBuilder class is defined, no classes are generated

[AutoGenerateBuilder(typeof(A))]
public partial class ABuilder {
}
[AutoGenerateBuilder(typeof(B))]
public partial class BBuilder {
}

A and B are third-party DTOs

My project :

<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <TargetFramework>net6.0</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>
        <Nullable>enable</Nullable>
        <IsPackable>true</IsPackable>
    </PropertyGroup>

    <ItemGroup>
        <PackageReference Include="FluentBuilder" Version="0.9.0"  PrivateAssets="All"/>
        <PackageReference Include="ABNuget" Version="xxx" />
    </ItemGroup>
</Project>
