我是新手并尝试使用以下代码建立SCP连接：
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println("Hello world");
org.apache.tools.ant.taskdefs.optional.ssh.Scp scp = new Scp();
int portSSH = 22;
String srvrSSH = "xx.xx.xx.xx";
String userSSH = "username";
String pswdSSH = "password";
String localFile = "C:\\xxx\\xxx.txt";
String remoteDir = "home/xxx/exports/xxx";
scp.setPort( portSSH );
scp.setLocalFile( localFile );
scp.setTodir( userSSH + ":" + pswdSSH + "@" + srvrSSH + ":" + remoteDir );
scp.setProject( new Project() );
scp.setTrust( true );
scp.execute();
}
我得到以下例外：
*Hello world
