java.io.IOException：无法运行程序＆＃34; svn＆＃34;：CreateProcess error = 2，系统找不到指定的文件

Question

我发现了类似的问题，但没有一个解决方案解决了我的问题。 我突然开始收到这个错误。

  

java.io.IOException：无法运行程序＆＃34; svn＆＃34;：CreateProcess error = 2，   该系统找不到指定的文件。

C：\ Program Files \ Java \ jdk1.8.0_152

命令是：

svn list --xml "+unfuddlefileurl+" --no-auth-cache --username " + unfuddleUserName + " --password " + unfuddlePassword

这是我的代码：

 public static int runCommand(String command, String directory, String[] envp, File outputFile) throws IOException, InterruptedException
    {                  
            logger.logDebug(CLASSNAME, "COMMAND is " + command + " directory = " + directory);          
            Runtime rt = Runtime.getRuntime();      
            File workingDirectory = null;
            if (directory != null)
                workingDirectory = new File(directory);             
            Process proc = rt.exec(command, envp, workingDirectory);

            // any error message?            
            StreamConsumer errorGobbler = new 
            StreamConsumer(proc.getErrorStream(), "ERROR", outputFile);            

            // any output?
            StreamConsumer outputGobbler = new 
            StreamConsumer(proc.getInputStream(), "OUTPUT", outputFile);

            // kick them off
            errorGobbler.start();
            outputGobbler.start();

            // Note: This close() was added to make powershell commands work.            
            proc.getOutputStream().close();

            // any error???
            return proc.waitFor();            
    }

为什么我会收到此错误，如何解决？
