我在jenkins shared library library中调用sh('pwd')想执行一个shell脚本却报如下错误

hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: net.somta.PipelineFactoryBuilder.sh() is applicable for argument types: (java.lang.String) values: [pwd]
Possible solutions: is(java.lang.Object), use([Ljava.lang.Object;), any(), use(java.util.List, groovy.lang.Closure), any(groovy.lang.Closure), use(java.lang.Class, groovy.lang.Closure)
