Jenkinspipe道中的Docker无法运行，因为环境variables无效：=
我试图在jenkinspipe道中运行一个docker容器，如下所示：
agent { docker { image 'indiehosters/git' reuseNode true } }
但pipe道无法运行。 看来一个无效的环境variables正在设置docker容器运行时。
我使用Jenkins版本2.65，Dockerpipe道插件1.11，Pipeline插件2.5
Jenkins控制台的堆栈跟踪：

好的解决了它。
基本上，jenkins有一个空的环境variables。 删除了空的variables，它的工作！
