我刚开始用Jenkins编写管道，似乎无法解决这个问题。我希望使用2个静态列表，并将第二个列表项附加到第一个列表项上。大多数情况下，我已经成功地做到了这一点，但我似乎无法找到一种方法来删除第二个列表项中的括号。最终，我将把编译部分分解为一个单独的库。
提前感谢所有能提供帮助的人。
我的代码：

def food = ["eggs","chips"]
def drink =["water","juice","cola"]
def meal = []

    for (String fd : food){
        [drink].transpose().each {drinks ->
            meal.add("Food: ${fd}, Drinks: ${drinks}")}
    }

pipeline {
    agent any

    stages {
        stage('Results') {
            steps {
                echo 'Results'
                echo "${meal}"
            }
        }
    }
}

结果（截短）

Results
[Pipeline] echo
[Food: eggs, Drinks: [water], Food: eggs, Drinks: [juice], Food: eggs, Drinks: [cola], Food: chips, Drinks: [water], Food: chips, Drinks: [juice], Food: chips, Drinks: [cola]]
[Pipeline] }

正如你可以看到的结果，我有我需要的，除了不能删除括号
