PublishCodeCoverageResults@2 v2.252.1任务超时错误求助

问题：Azure DevOps PublishCodeCoverageResults@2 v2.252.1版本发布覆盖率报告超时

我们使用以下任务配置发布Cobertura测试覆盖率报告：

- task: PublishCodeCoverageResults@2
  displayName: 'Publish code coverage results'
  condition: eq(variables['isTestRun'], 'true')
  continueOnError: true
  timeoutInMinutes: 1
  inputs:
    summaryFileLocation: $(Build.Repository.LocalPath)/$(Build.Repository.Name)/coverage/coverage/cobertura.xml
  env:
    NODE_NO_WARNINGS: 1

该任务在v2.48.1版本时运行正常，但升级至v2.252.1版本后，出现HTTP请求超时错误，具体日志如下：

Finishing: Publish code coverage results

解决方案汇总

回滚至稳定版本：直接指定使用v2.48.1版本的任务，修改任务定义为：

- task: PublishCodeCoverageResults@2.48.1
  displayName: 'Publish code coverage results'
  condition: eq(variables['isTestRun'], 'true')
  continueOnError: true
  timeoutInMinutes: 1
  inputs:
    summaryFileLocation: $(Build.Repository.LocalPath)/$(Build.Repository.Name)/coverage/coverage/cobertura.xml
  env:
    NODE_NO_WARNINGS: 1

此方法可快速恢复流水线正常运行，避免新版本带来的问题。

延长任务超时时间：当前任务仅设置1分钟超时，可适当延长至3-5分钟，给任务足够的连接和处理时间：
```
timeoutInMinutes: 3
```
检查并优化覆盖率文件：若cobertura.xml文件过大，新版本任务处理时可能因负载过高触发超时。可通过以下方式优化：
- 排除测试文件、第三方依赖等无需统计的内容
- 拆分覆盖率报告为多个小文件，分批发布
排查网络连接问题：如果使用自托管代理，需确认：
- 代理机器能正常访问Azure DevOps服务端，无防火墙或代理拦截
- 代理服务器配置正确，新版本任务可能对网络请求的处理逻辑有变更，需确保相关域名在白名单中
关注官方修复动态：该版本的超时问题属于已知的兼容性问题，部分用户反馈在后续小版本更新中得到修复，可关注任务的更新日志，待修复版本发布后再升级。
