解决方案 #

1. 将签名环境变量传递到Publish步骤 #

dotnet publish会独立触发构建流程，Build步骤中设置的环境变量不会自动传递到Publish步骤。可通过两种方式解决：

方式一：提升到Job级别（推荐）

将env块移到build-and-deploy job下，让所有步骤共享环境变量：

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    env:
      KEYSTORE_PATH: ${{ github.workspace }}/正确的密钥库文件路径 # 替换为实际路径
      KEYSTORE_PASSWORD: ${{ secrets.KEYSTORE_PASSWORD }}
      KEYSTORE_ALIAS: ${{ secrets.KEYSTORE_ALIAS }}
      KEY_PASSWORD: ${{ secrets.KEY_PASSWORD }}
    steps:
      # 后续步骤保持不变，移除Build步骤中的env块

方式二：在Publish步骤单独添加env

- name: Publish
  run: dotnet publish ProjetSport/ProjetSport/ProjetSport.csproj --framework net7.0-android --configuration Release --output ./publish/android
  env:
    KEYSTORE_PATH: ${{ github.workspace }}/正确的密钥库文件路径 # 替换为实际路径
    KEYSTORE_PASSWORD: ${{ secrets.KEYSTORE_PASSWORD }}
    KEYSTORE_ALIAS: ${{ secrets.KEYSTORE_ALIAS }}
    KEY_PASSWORD: ${{ secrets.KEY_PASSWORD }}

2. 验证密钥库文件路径的正确性 #

确保KEYSTORE_PATH指向的文件确实存在，修改Check Keystore File步骤直接检查目标路径：

- name: Check Keystore File
  run: ls -la "${{ github.workspace }}/正确的密钥库文件路径" # 替换为实际路径

若路径包含空格，必须用引号包裹避免解析错误。

3. 限定csproj签名配置仅针对Release环境（可选） #

将签名配置放在Release专属的PropertyGroup中，避免其他环境干扰：

<PropertyGroup Condition="'$(Configuration)' == 'Release'">
  <AndroidKeyStore>True</AndroidKeyStore>
  <AndroidSigningKeyStore>$(KEYSTORE_PATH)</AndroidSigningKeyStore>
  <AndroidSigningStorePass>$(KEYSTORE_PASSWORD)</AndroidSigningStorePass>
  <AndroidSigningKeyAlias>$(KEYSTORE_ALIAS)</AndroidSigningKeyAlias>
  <AndroidSigningKeyPass>$(KEY_PASSWORD)</AndroidSigningKeyPass>
</PropertyGroup>
