当我将test（）调用放入脚本中时，我得到了 NonSerializableException ，当我注释掉 A 行而未注释掉 B 行时，它工作得很好。
与test()在脚本内部和外部进行调用有什么区别？
test()
我现在正在考虑的解决方法是使用when条件Jenkinsfile
when
Jenkinsfile
更新 我怀疑该错误与需要“节点”块的命令有关

首先JsonSlurper是不可序列化的。如果要使用它，则必须将其封装到@NonCPS方法中。
JsonSlurper
@NonCPS
其次，您不能在@NonCPS方法中使用任何cps方法，例如sh。
sh
第三，如果您不遵循这些规则，有时管道（cps代码）运行程序不会立即引发错误。有时，对脚本本身进行一些更改后会引发错误。
