如何在Jenkins UI中执行本地python脚本

Question

我是Jenkins的新手,最近想安排一个工作来执行本地python脚本.我还没有源代码控制,所以在Jenkins UI中创建作业时,我在源代码管理中选择了"无".

我做了一些关于如何在Jenkins UI中执行python脚本的研究,我尝试使用Python插件来执行python脚本作为构建步骤.但它失败了.(但实际上我不想使用这个插件,因为我的脚本需要输入参数,所以我认为我需要在BUILD字段中选择类似"执行shell"的东西 - 我试过但也失败了)任何人都可以帮我找出如何正确运行/调用本地python脚本？

PS:我也不清楚Jenkins工作区及其工作原理？如果有人可以为我澄清,那将是适当的.

这是我在失败构建后获得的控制台输出:

Answer 1

创建一个Jenkins作业,并从jenkins作业中将脚本作为shell脚本运行.像这样

#!/bin/sh
python <absolute_path_of_python_script>.py

Answer 2

您可以将所有python脚本实际复制到Build部分下的"execute shell"中,而不是在每个服务器上处理本地脚本文件.它必须从相关的python shebang开始.例如:

#!/usr/bin/env python
your script...

您还可以在作业中添加参数并在python脚本中使用环境变量.例如

parameter1 = os.environ['parameter1']
