Groovy Ant - filter语言 - chain包含错误

Question

我想将日志文件中的行复制到单独的文件中。它应该只从给定的列表中复制那些包含ip的行。

//EDIT -用于测试的更详细的代码下面是我的代码:

static String[] ips = [
"192.168.1.2",
"192.168.1.1"
];
public static void main(String[] args) {
    AntBuilder ant = new AntBuilder();
    String folder = 'C:/logs';
    ips.each {
        String ip = it;
        File file = new File("${folder}/singular_incidents/${ip}.txt")
        ant.copy(tofile:"${folder}/singular_incidents/${ip}.txt"){
            fileset(dir: folder){
                include(name:"*access*.log")
            }
            filterchain(){
                linecontains(){
                    contains(ip)
                }
            }
        }
    }
}

AND日志文件(accesslog-2014-05-05.log)的内容可能如下所示

192.168.1.1 - user1 [24/Apr/2014:15:51:06 +0200] 'GET HTTP/1.1' 192.168.1.1 - user1 [24/Apr/2014:15:51:38 +0200] 'POST ' 192.168.1.2 - user2 [24/Apr/2014:15:51:40 +0200] 'POST ' 192.168.1.3 - user3 [24/Apr/2014:16:60:40 +0200] 'POST '

目标是我应该得到两个带名称的独立文件—192.168.1.1.txt—包含两个首行- 192.168.1.2.txt -包含第三行

不幸的是，当使用lincontains时，我得到了这个错误(我混淆了实际的ip字符串):

Caught: class org.apache.tools.ant.filters.LineContains$Contains doesn't support nested text data ("555.555.555.555")

希望这对你有帮助:

String[] ips = [
    "192.168.1.2",
    "192.168.1.1"
]
def ant = new AntBuilder()
def dest = new File('/tmp')
new File('.').eachFileMatch(~/access.*.log/) { log ->
   ips.each { ip ->
        File file = new File(dest, "${ip}.txt")
        ant.copy(file: log.name, tofile: "$dest.absolutePath/${ip}.txt") {
            filterchain() {
                linecontains() {
                    contains(value: "$ip")
                }
            }
        }
    } 
}
