从java执行的rsync返回，未找到文件错误

我试图使用ApacheCommonsExec库执行rsync命令（atm本地测试），我得到一条错误消息，而在终端中执行相同的命令显示没有问题

这是我要执行的命令：

rsync -zve "ssh -i /home/user/.ssh/testkey" /home/user/playground/src/HNI_0084.JPG user@localhost:/home/user/playground/dst

这是我在Java类中执行命令时收到的错误消息：

rsync: Failed to exec ssh -i /home/user/.ssh/testkey: No such file or directory (2)
rsync error: error in IPC code (code 14) at pipe.c(84) [sender=3.0.9]
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in IPC code (code 14) at io.c(605) [sender=3.0.9]
org.apache.commons.exec.ExecuteException: Process exited with an error: 14 (Exit value: 14)
    at org.apache.commons.exec.DefaultExecutor.executeInternal(DefaultExecutor.java:377)
at org.apache.commons.exec.DefaultExecutor.execute(DefaultExecutor.java:160)
at org.apache.commons.exec.DefaultExecutor.execute(DefaultExecutor.java:147)
    at LocalExecutor.execute(LocalExecutor.java:21)

这是我用来执行本地命令的java类：

import java.io.IOException;

import org.apache.commons.exec.CommandLine;
import org.apache.commons.exec.DefaultExecutor;
import org.apache.commons.exec.ExecuteWatchdog;

public class LocalExecutor {

    public int execute(String command, String[] args) {
        CommandLine cl = new CommandLine(command);
        cl.addArguments(args);
        System.out.println(cl.toString());

        DefaultExecutor executor = new DefaultExecutor();
        ExecuteWatchdog watchdog = new ExecuteWatchdog(60000);
        executor.setWatchdog(watchdog);
        int exitValue = 0;
        try {
            exitValue = executor.execute(cl);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return exitValue;
    }

}

最后，传递给程序的参数数组如下：

{-zve, ssh -i /home/user/.ssh/testkey, /home/user/playground/src/HNI_0084.JPG, user@localhost:/home/user/playground/dst/}

完全不知道为什么rsync会抱怨这个调用，因为引用包含空格的参数是由库处理的，而实际的rsync调用应该与我上面发布的行完全相同

有什么想法吗/

从java代码执行时，rsync可能找不到ssh。尝试使用ssh exectable的完整路径，而不仅仅是传递命令
