运行 Jenkins 管道时如何修复 'script returned exit code 1'

Question

我正在使用 Jenkins Blue Ocean 定义管道。

我正在尝试做一个简单的 python pep8 编码约定，但如果我进入 shell 并直接键入命令，它运行正常。

但是在管道中执行同样的命令时，执行了，但是在最后 'script returned exit code 1' 显示。由于这个错误代码，它不会进入下一步。

有解决办法吗？

script returned exit code 1

Answer 1

我遇到了同样的问题，批处理脚本调用了一个可执行文件，其 return 状态在成功时为 1，在错误时为 0。

对于 Jenkins 来说，这是一个问题，成功错误代码为 0，任何其他状态代码均表示失败，因此停止作业并显示以下消息：script returned exit code 1

我的解决方法：检查最后一个错误代码并反转脚本的 return 值：

stages {        
    stage("My stage") {            
        steps {
            bat label: 'My batch script',
                script: ''' @echo off
                            return_1_if_success.exe   // command which returns 1 in case of success, 0 otherwise
                            IF %ERRORLEVEL% EQU 1 (exit /B 0) ELSE (exit /B 1)'''
        }
    }
}

解释：

IF %ERRORLEVEL% EQU 1 (exit /B 0) ELSE (exit /B 1)
// if previous command returned 1 (meaning success for this command), 
// then we exit with return code 0 (meaning success for Jenkins),
// otherwise we exit with return code 1 (meaning failure for Jenkins)

在 Windows cmd 上，%ERRORLEVEL% 保存在 cmd.exe 终端或批处理脚本中给定点遇到的最后一个错误代码。

对于 PowerShell，您可能想要检查 $? 而不是 ERRORLEVEL，我会让您检查其他 shell 和平台的等效项。

令我惊讶的是，寻找这个问题的人比我想象的要多。

如果您打算将代码运行的错误代码出口 1 作为 shell 脚本忽略，请使用 set +e。
