我想執行一個rsync命令(atm測試本地)使用Apache Commons Exec庫和我得到一個錯誤消息,而在終端執行相同的命令顯示沒有問題。從java執行rsync返回與文件未找到錯誤
這是我想執行的命令:
rsync -zve "ssh -i /home/user/.ssh/testkey" /home/user/playground/src/HNI_0084.JPG [email protected]:/home/user/playground/dst
這是錯誤消息我得到的,當我在我的Java類執行命令:
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)
所以,是的,這是我的Java類執行本地命令:
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;
}
}
最後,參數數組傳遞給程序是這樣的:
{-zve, ssh -i /home/user/.ssh/testkey, /home/user/playground/src/HNI_0084.JPG, [email protected]:/home/user/playground/dst/}
完全無能,爲什麼會rsync的抱怨電話,因爲包含空格被庫和實際rsync的呼叫處理參數的報價則應該看起來就像我上面貼線。
任何想法? :/
