我想从输出中删除以下行

 Volume in drive C has no label.
 Volume Serial Number is 1878-D614

 Directory of C:\Information\DataTransformation\externLibs\system

我的代码

def externalLibrarySystem(csm,pluginOutputs)
{
String rs = (String)pluginOutputs.get("ExternalLibrarySystem")
String temp=rs

csm.externalLibrarySystem(rs)
{
    "${rs}"
}
}

---

注意：在Java中，当您使用Scanner类时，temp具有dir输出。 将一行一行复制到StringBuilder。有一个int计数器，不要附加前5行

String rs = (String)pluginOutputs.get("ExternalLibrarySystem");
StringBuilder sb = new StringBuilder();
Scanner sc = new Scanner(rs);
  int cnt = 0;
  while (sc.hasNextLine()) {
   if(cnt>4){
      sb.append(sc.nextLine()+System.getProperty("line.separator"));
   }
   cnt++;
  }
String temp = sb.toString();
