java.lang.NoSuchMethodError：没有这样的 DSL 方法“readJSON”答案

【问题标题】：java.lang.NoSuchMethodError: No such DSL method 'readJSON'java.lang.NoSuchMethodError：没有这样的 DSL 方法“readJSON”
【发布时间】：2017-10-20 03:12:43
【问题描述】：

def data = readJSON text: '{"rel" : {"configVersion": "1.0","manifest" :"'+"${manifestURL}"+'"}}'
writeJSON(file: 'C:\\Users\\Public\\json\\config.json', json: data)

我在我的 Jenkins 管道中使用 JSON 函数并获得 NoSuchMethodFoundError。我正在使用 Jenkins 2.85。

知道如何解决这个问题吗？

【解决方案1】：

使用Pipeline Utility Steps Plugin，您可以使用readJSON 函数。

def props = readJSON text: '{ "key": "value" }'

没有这个插件你不能使用这个功能。
