使用来自另一个地图 <String, List<String>> 的选择性元素创建一个新地图 <String, List<String>>

Question

我正在尝试使用来自另一个 Map <String, List<String>> invoiceErrorLines

的选择性元素创建一个新的 Map <String, List<String>> headErrors

invoiceErrorLines = ['1660277':['Line : 1 Invoice does not foot Reported', 'Line : 2 MATH ERROR'], 
                    '1660278':['Line : 5 Invoice does not foot Reported', 'cl_id is a required field'], 
                    '1660279':['Line : 7 could not parse date ', 'File Error : The file doesnt have delimiter'], 
                    '1660280':['Line : 9 Invoice error']]
def regex = "^Line\s(?:(\d+)\s)?\s*:\s+(\d+)?.+"
def headErrors = invoiceErrorLines.each{ inv ->
   inv.value.findAll{it.contains('Invoice does not foot Reported') || !(it ==~ regex) }.groupBy{inv.key} 
}

新地图应包含作为键的发票编号及其相应的错误消息，该错误消息与 regex = "^Line\s(?:(\d+)\s)?\s*:\s+(\d+)?.+" 不匹配但包含 Invoice does not foot Reported

当我打印 headErrors 时，我看到的地图与 invoiceErrorLines 相同，但是我期待 headErrors 如下

headErrors = ['1660277':['Line : 1 Invoice does not foot Reported'], 
              '1660278':['Line : 5 Invoice does not foot Reported', 'cl_id is a required field'], 
              '1660279':['File Error : The file doesnt have delimiter'] 
             ]

有人可以帮我解决这个问题吗？

有

def headErrors = invoiceErrorLines.collectEntries{ key, value ->
   value.findAll{ it.contains('Invoice does not foot Reported') || !(it ==~ regex) }.groupBy{ key }
}

它产生

[1660277:[Line : 1 Invoice does not foot Reported], 1660278:[Line : 5 Invoice does not foot Reported, cl_id is a required field], 1660279:[File Error : The file doesnt have delimiter]]
