Shell 执行失败的原因排查

问题描述

jenkins 任务中，有一个步骤是执行一个 shell 命令执行 c#中的一个方法导出 package，命令如下

/Applications/Unity/Hub/Editor/2022.3.22f1/Unity.app/Contents/MacOS/Unity -quit -batchmode -projectPath /Users/jenkins/jenkins_home/workspace/sdk/zeussdk-ci/Unity/ZeusSDK -executeMethod ExportPackage.ExportAssetsPackage

执行失败，报错如下：

Aborting batchmode due to failure:
executeMethod method ExportPackage.ExportAssetsPackage threw exception.

build job start
Traceback (most recent call last):
  File "_continuous_integration_delivery/pipeline.py", line 409, in <module>
    build()
  File "_continuous_integration_delivery/pipeline.py", line 142, in build
    buildUnity(ios_basic_path, unity_basic_path, unity_zeusinfoplist_path)
  File "_continuous_integration_delivery/pipeline.py", line 352, in buildUnity
    + " -executeMethod ExportPackage.ExportAssetsPackage " + unity_basic_path)
  File "/Users/jenkins/jenkins_home/workspace/sdk/zeussdk-ci/venv/lib/python3.6/site-packages/eve/base/command_toolkit.py", line 51, in run_external_command
    raise RunCommandException(msg)
eve.base.exception.RunCommandException: ErrorCode: 1, Command: /Applications/Unity/Hub/Editor/2022.3.22f1/Unity.app/Contents/MacOS/Unity -quit -batchmode -projectPath /Users/jenkins/jenkins_home/workspace/sdk/zeussdk-ci/Unity/ZeusSDK -executeMethod ExportPackage.ExportAssetsPackage /Users/jenkins/jenkins_home/workspace/sdk/zeussdk-ci/ci_output/Unity/ZeusSDK_v3.0.6-SNAPSHOT, STDOUT: None, STDERR: 

从报错信息中，完全无法看出是在哪里抛出了什么异常。

原因排查

手动执行该命令，添加日志输出-logFile

/Applications/Unity/Hub/Editor/2022.3.22f1/Unity.app/Contents/MacOS/Unity -quit -batchmode -projectPath /Users/jenkins/jenkins_home/workspace/sdk/zeussdk-ci/Unity/ZeusSDK -executeMethod ExportPackage.ExportAssetsPackage -logFile /Users/jenkins/logs/logfile.txt

会在输出目录下生成一个 logfile.txt 文件，里面会输出详细的错误信息

可以看到错误原因是缺少某个目录，导致无法找到路径。
