脚本块内的NonSerializableException

时间：2018-05-02 05:56:20

标签： jenkins jenkins-pipeline

当我将test（）调用放入脚本中时，我得到 NonSerializableException ，当我注释掉 A 行并取消注释掉行 B ，它工作得很好。

在脚本内部和外部调用test()有什么区别？

我现在正在考虑的解决方法是使用when的{​​{1}}条件

更新 我怀疑该错误与Commands Requiring a “node” Block

答案 0 :(得分：1)

首先JsonSlurper不可序列化。如果要使用它，则必须将其封装到@NonCPS方法中。

其次，您无法在@NonCPS方法中使用任何cps方法，例如sh。

第三，如果你不遵守这些规则，有时管道（cps代码）运行器不会立即引发错误。有时在对脚本执行某些更改后会抛出错误。
