jekins 从gitlab 拉取代码失败，文件名太长 Filename too long

队友一大早提交了代码，然后jekins自动部署就执行失败了。一脸懵逼的看了下控制台日志：

关键信息其实就一行:

出于隐私，文件名我已经改成a了，原文件名还是挺长的。

那么怎么解决呢？总不能让人家改源码的文件名吧

其实很简单，就是一个git的配置而已

git config --global core.longpaths  true

但是这个全局的配置要怎么加呢？这个才是关键的地方。

本质就是在拉代码之前，执行的一个环境参数的命令

解决步骤如下：

1. 安装插件jekins插件 Environment Injector

2.选择要执行的item，增加环境变量

3.配置变量设置脚本

4.保存，重新执行部署脚本，运行成功
