使用GitHub Actions部署Azure App Service时找不到工件问题

构建流程执行成功，但部署步骤报错Error: Unable to find any artifacts for the associated workflow.，结合你的工作流配置，问题主要出在工件路径匹配和部署阶段的文件定位上，以下是具体修复方案：

1. 确认Maven生成正确的WAR文件 #

很多Spring Boot项目默认打包为JAR，需先在pom.xml中明确指定打包类型：

<packaging>war</packaging>

如果需要适配Azure App Service的容器，可额外添加排除内嵌Tomcat的配置（可选）：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

2. 修正工作流路径配置 #

构建阶段：优化上传路径并添加文件验证 #

原上传路径可简化，同时新增一步验证WAR文件是否生成，避免空上传：

- name: Verify WAR file exists
  run: ls -la target/

- name: Upload artifact for deployment job
  uses: actions/upload-artifact@v3
  with:
    name: java-app
    path: target/*.war

部署阶段：修正部署包路径 #

下载工件后，文件会存放在当前工作目录的java-app子文件夹下（对应artifact名称），原配置中package: '*.war'会在根目录查找，自然找不到文件，需修改为：

- name: Deploy to Azure Web App
  id: deploy-to-webapp
  uses: azure/webapps-deploy@v2
  with:
    app-name: 'webApp12dg'
    slot-name: 'Production'
    publish-profile: ${{ secrets.AZUREAPPSERVICE_PUBLISHPROFILE_F2A6B2A7E43B4D568F7E92A0E5D97521 }}
    package: java-app/*.war

          publish-profile: ${{ secrets.AZUREAPPSERVICE_PUBLISHPROFILE_F2A6B2A7E43B4D568F7E92A0E5D97521 }}
          package: java-app/*.war

额外排查点 #

• 查看构建日志中"Upload artifact for deployment job"步骤的输出，确认是否成功上传文件
• 查看部署日志中"Download artifact from build job"步骤的输出，确认是否成功下载文件
• 如果Maven配置了<finalName>自定义文件名，需确保path和package中的路径匹配该文件名
