final_map = ["/7amd64-Aug2022.1":"2022-08-09","/7amd64-Oct2022.1":"2022-10-12","/7":"2022-11-08","/7amd64-Jul2022.1":"2022-07-12","/7amd64":"2022-11-08","/7amd64-June2022.1":"2022-06-14","/7amd64-beta":"2022-11-08","/7amd64-Sep2022.1":"2022-09-14","/7amd64-Nov2022.1":"2022-11-08","/_uploads":"2022-11-08"]

Jenkins管道（下面是我的代码，这是不工作）

result = final_map.sort { a,b -> a.value <=> b.value }
echo "Output: ${result}"

期望使用日期（值）对Map进行排序。

您可以为此使用自定义比较器。检查以下Groovy代码。

final_map = ["/7amd64-Aug2022.1":"2022-08-09","/7amd64-Oct2022.1":"2022-10-12","/7":"2022-11-08","/7amd64-Jul2022.1":"2022-07-12","/7amd64":"2022-11-08","/7amd64-June2022.1":"2022-06-14","/7amd64-beta":"2022-11-08","/7amd64-Sep2022.1":"2022-09-14","/7amd64-Nov2022.1":"2022-11-08","/_uploads":"2022-11-08"]

final_map.sort { s1, s2 -> 

        def s1Date = new Date(s1.value.replace('-', '/'))
        def s2Date = new Date(s2.value.replace('-', '/'))
 
        if( s1Date.before(s2Date)) {
            return -1
        } else {
            return 1
        } 
    }
println final_map
