    Thanks Msiadak and HimanshuTayal, I was able to solve it at last  below is the generic function that I used and solved most of my needs 

    private void compare(def expected, def actual, def ignore)
    {
    def expectedParse = new JsonSlurper().parseText(expected)
    def actualParse = new JsonSlurper().parseText(actual)
    def parentnode
    def dynmaicparent
    def ignorefields = ignore.split(',')
    for(int i =0; i <ignorefields.size(); i++){
    values=ignorefields[i].trim()
    //log.info( i + "id to remove " + values)
    if(values.contains('.')){
    parentnode = values.tokenize(".")[0]
    childnode = values.substring(parentnode.length()+1)
    log.info( expectedParse.get(parentnode).size())
    for(int j =0; j <expectedParse.get(parentnode).size(); j++){
    expectedParse.get(parentnode).get(j).remove(childnode)
    actualParse.get(parentnode).get(j).remove(childnode)
    }
    }
    else
    {
    expectedParse.remove(values)
    actualParse.remove(values)
    }
    }
    log.info("after removing ignore field $expectedParse")
    log.info("updated actualParse is $actualParse")
    assert expectedParse == actualParse
    }

As you written some values are dynamically changing, so is it changing for 1 json and not changing for another json?

 

if this is the scenario then you need to write your custom code to match two json by ignoring those dynamic fields.
