嗨，我是 groovy 的新手。
我正在使用 jenkins 进行构建，现在我的要求是捕获构建结果，例如（Success/Unstable.Failure）并将其打印在构建电子邮件的主题行上。
我已经安装了 groovy postbuild 插件并尝试执行以下几行但没有成功：
导入 hudson.model.*
status = manager.build.result println ${status}
然后我会在我的 email-ext 插件的主题行中包含状态变量。
但我收到以下错误：
Groovy script failed:
groovy.lang.MissingMethodException: No signature of method: Script1.$() is applicable for argument types: (Script1$_run_closure1) values: [Script1$_run_closure1@2620749c]
Possible solutions: is(java.lang.Object), run(), run(), any(), use([Ljava.lang.Object;), any(groovy.lang.Closure)
