Azure DevOps发布至App Center后所有版本均显示为1.0(1)问题

问题现象 #

用.NET Maui开发的Android应用，在Azure DevOps上配置了CI/CD流水线。CD执行成功后，App Center里显示的所有版本都是同一个，和CI流水线设置的版本对不上。用来更新版本信息的Bash脚本执行时提示AndroidManifest.xml文件不存在，但AssemblyInfo.cs的版本号已经更新成功。

原脚本内容 #

ANDROID_MANIFEST_FILE="AndroidManifest.xml"

if [[ ${{ parameters.SetVersionCodeInManifest }} == True ]]
then
  VERSION_CODE="$(Azure_DevOps_BUILD_ID)"

  echo "Updating Android build information. New version code $VERSION_CODE"

  sed -i '' -e 's/versionCode="1"/versionCode="'$VERSION_CODE'"/' $ANDROID_MANIFEST_FILE
fi

VERSION_NAME=$(App_BUILD_NUMBER)

echo "Updating Android build information. New version name $VERSION_NAME"

sed -i '' -e 's/versionName="[0-9.]*"/versionName="'$VERSION_NAME'"/' $ANDROID_MANIFEST_FILE

cat $ANDROID_MANIFEST_FILE

# Set AssemblyInfo
assemblyInfoPath='assemblyinfo.cs'
echo "assemblyInfoPath: $assemblyInfoPath"
sed -i '' -e 's/"[0-9]*\.[0-9]*\.[0-9]*\.[0-9]*"/"'$(App_BUILD_NUMBER)'"/' "$assemblyInfoPath"
cat $assemblyInfoPath

脚本执行结果 #

错误原因分析 #

1. 文件路径错误：脚本里ANDROID_MANIFEST_FILE只写了文件名，没指定完整相对路径。.NET Maui项目中AndroidManifest.xml的实际路径是Platforms/Android/AndroidManifest.xml，流水线工作目录下找不到该文件。
2. Sed命令参数不兼容：sed -i ''是macOS系统的写法，但Azure DevOps默认用Ubuntu代理，Linux环境下sed -i不需要空引号，空引号会被当成无效文件路径，导致sed: can't read : No such file or directory错误。
3. 变量引用错误：脚本里Azure_DevOps_BUILD_ID和App_BUILD_NUMBER的引用方式不对，Azure DevOps流水线变量应该用$(Build.BuildId)（内置构建ID变量）和$(App_BUILD_NUMBER)（自定义变量）的格式。

修复方案 #

1. 修正文件路径 #

把ANDROID_MANIFEST_FILE设置为完整相对路径：

ANDROID_MANIFEST_FILE="Platforms/Android/AndroidManifest.xml"

2. 适配Linux环境的Sed命令 #

移除sed -i后面的空引号，改成Linux兼容的写法：

# 修改versionCode的sed命令
sed -i -e 's/versionCode="1"/versionCode="'$VERSION_CODE'"/' $ANDROID_MANIFEST_FILE
# 修改versionName的sed命令
sed -i -e 's/versionName="[0-9.]*"/versionName="'$VERSION_NAME'"/' $ANDROID_MANIFEST_FILE

3. 修正变量引用方式 #

使用Azure DevOps正确的变量格式：

VERSION_CODE="$(Build.BuildId)"
VERSION_NAME="$(App_BUILD_NUMBER)"

4. 可选：添加文件存在检查 #

在操作文件前先检查文件是否存在，避免报错中断流水线：

if [[ ! -f $ANDROID_MANIFEST_FILE ]]; then
  echo "Error: $ANDROID_MANIFEST_FILE not found in current directory!"
  exit 1
fi

完整修复后的脚本 #

ANDROID_MANIFEST_FILE="Platforms/Android/AndroidManifest.xml"

# 检查文件是否存在
if [[ ! -f $ANDROID_MANIFEST_FILE ]]; then
  echo "Error: $ANDROID_MANIFEST_FILE not found!"
  exit 1
fi

if [[ ${{ parameters.SetVersionCodeInManifest }} == True ]]
then
  VERSION_CODE="$(Build.BuildId)"

  echo "Updating Android build information. New version code $VERSION_CODE"

  sed -i -e 's/versionCode="1"/versionCode="'$VERSION_CODE'"/' $ANDROID_MANIFEST_FILE
fi

VERSION_NAME="$(App_BUILD_NUMBER)"

echo "Updating Android build information. New version name $VERSION_NAME"

sed -i -e 's/versionName="[0-9.]*"/versionName="'$VERSION_NAME'"/' $ANDROID_MANIFEST_FILE

cat $ANDROID_MANIFEST_FILE

# Set AssemblyInfo
assemblyInfoPath='Properties/assemblyinfo.cs'
echo "assemblyInfoPath: $assemblyInfoPath"
# 同样适配sed参数
sed -i -e 's/"[0-9]*\.[0-9]*\.[0-9]*\.[0-9]*"/"'$(App_BUILD_NUMBER)'"/' "$assemblyInfoPath"
cat $assemblyInfoPath
