Azure Pipeline构建.NET 8 MAUI项目遇XABBA7009错误的解决咨询

我创建了一个Visual Studio 2022默认的.NET 8.0 MAUI项目TestMauiApp，随后向解决方案添加了MAUI类库MauiLibrary并在项目中引用。在Azure Pipeline构建时出现XABBA7009错误：

       "/Users/runner/work/1/s/TestMauiApp/SkiaGum.Mobile/MauiLibrary.csproj" (SignAndroidPackage target) (3) -

我找不到相关问题信息，不知道怎么解决。

更新1 #

我尝试在MauiLibrary的csproj文件中添加以下配置：

<AndroidEnableAssemblyCompression>false</AndroidEnableAssemblyCompression>

虽然绕过了原错误，但出现了同编号的新错误：

我不确定这是不是有效解决方法，而且问题没解决。如果从解决方案中移除MauiLibrary，项目构建完全正常。

针对这个XABBA7009错误，有几个可行的解决方向：

1. 调整构建目标，直接构建主项目而非解决方案 #

问题出在构建解决方案时，MAUI类库被单独执行了SignAndroidPackage目标，而类库本身不需要签名打包操作。修改构建脚本，直接指定主项目（TestMauiApp.csproj）而非解决方案：

dotnet build TestMauiApp/TestMauiApp.csproj -f net8.0-android -c Release -v d -t:SignAndroidPackage -p:AndroidPackageFormat=aab -p:AndroidKeyStore=True -p:AndroidSigningKeyStore=$(keystore.secureFilePath) -p:AndroidSigningStorePass=storePass -p:AndroidSigningKeyAlias=keyAlias -p:AndroidSigningKeyPass=keyPass

这样只会处理主项目，类库作为依赖被正确打包进主项目的AAB，不会触发类库的错误打包流程。

2. 禁用类库的Android打包相关目标 #

在MauiLibrary.csproj中添加配置，阻止类库执行Android打包相关任务：

<PropertyGroup>
  <IsPackable>false</IsPackable>
  <AndroidPackageFormat>None</AndroidPackageFormat>
</PropertyGroup>

这会告诉构建系统，这个类库不需要生成独立的Android包，避免触发错误的_BuildApkEmbed任务。

3. 更新.NET MAUI workload到最新版本 #

你的构建脚本中使用了dotnet7的源来安装workload，这可能导致版本不兼容。修改安装命令，使用dotnet8的官方源：

dotnet workload install android ios maui --source https://api.nuget.org/v3/index.json

同时确保使用的.NET SDK版本是8.0.x的最新稳定版，比如8.0.200或更高，修复已知的构建bug。

4. 清理构建缓存并重新还原 #

在构建前增加更彻底的清理步骤：

dotnet clean TestMauiApp.sln
dotnet nuget locals all --clear
dotnet restore TestMauiApp.sln

避免缓存的旧构建文件导致的冲突。
