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，但是如果我进入外壳并直接键入命令，它将运行正常。

但是当在管道中执行相同的命令时，将执行该命令，但最后显示“脚本返回的退出代码1”。由于出现此错误代码，因此无法进行下一步。

有解决方法吗？

script returned exit code 1

Answer 1

令我惊讶的是，更多的人正在寻找这个问题。

如果要忽略作为Shell脚本运行的代码的错误代码出口1，请使用set +e。

Answer 2

有运气吗？ @윤태일 遇到类似的情况，它只是作为管道的一部分而失败，而在手动时总是会成功。

Answer 3

蝙蝠脚本调用可执行文件时遇到同样的问题，成功时返回状态为1，错误时返回状态为0。

这对詹金斯（Jenkins）来说都是一个问题，对于詹金斯（Jenkins）来说，成功错误代码为0，其他任何状态代码都表示失败，因此通过以下消息停止了作业：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返回值：

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)'''
        }
    }
}

说明：

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%保留在cmd.exe终端或批处理脚本中给定点遇到的最后错误代码。

对于powershell，您可能需要检查$?而不是ERRORLEVEL，让我检查一下其他外壳和平台的等效性。
