哈德森*.groovy在詹金斯找不到

我正在尝试使用groovy脚本配置jenkins作业,我不知道我在配置上做错了什么我甚至无法执行简单的groovy命令

println System.getenv("PATH")

当jenkins尝试构建时,它会显示以下堆栈跟踪,然后抛出以下错误

[workspace] $ groovy "C:\Program Files (x86)\Jenkins\jobs\{Project_Name}\workspace\hudson2392295018240496017.groovy"

我groovy version在jenkins配置中使用默认值并为groovy安装了jenkins插件.

我是jenkins和groovy的新手.提前致谢.
