我需要实现Firebase推送通知，所以我将最新版本的包添加到我的Maui .net8.0项目中。以下是在 csproj 文件中添加的用于推送通知的包。当我升级到这些软件包的最新版本时，我收到与错误 JAVA0000 相关的错误。
<ItemGroup Condition="'$(TargetFramework)' == 'net8.0-android'">
<GoogleServicesJson Include="google-services.json" />
<PackageReference Include="Xamarin.Firebase.Dynamic.Links">
<Version>121.2.0.2</Version>
</PackageReference>
<PackageReference Include="Xamarin.Firebase.Messaging">
<Version>123.3.1.2</Version>
</PackageReference>
</ItemGroup>
这是我面临的错误>

FirebaseMauiApp1 1
我参考了更多文档和讨论，他们建议添加其他包
"Xamarin.Build.Download"<Package Reference Include="Xamarin.AndroidX.Fragment.Ktx" Version="1.6.2.2" />但我仍然面临同样的问题。另外，我尝试使用降级版本，它对我来说很有效，但我需要使用最新版本而不使用任何其他包来实现 firebase 推送通知。
我不知道为什么它会导致错误，即使我没有添加“android collection .jvm”包。 请帮助我摆脱这个问题。感谢您的支持并提前致谢。
尝试添加包：
<PackageReference Include="Xamarin.AndroidX.Collection.Jvm" Version="1.4.0.1" />
在此处查看更多信息：https://github.com/xamarin/GooglePlayServicesComponents/issues/852当包与隐式引入的依赖项不完全同步时，此问题时常会发生。
