以参数结尾的Execute命令以：error = 2结尾，系统找不到指定的文件

Question

I have some trouble with my code to run a program on Windows command line. My intension is to update a version control repository with the svn.exe. This program needs the update -u parameter and the path to the repository (eg C:\\Projects\\Reposirtory). When I execute the code as seen below I get this error:

Cannot run program "C:\\Program Files\\SlikSvn\\bin\\svn status -u "C:\\Projects\\Reposirtory"": CreateProcess error=2, The system cannot find the file specified

public void checkUpdates(String baseDir)
    {
        StringBuilder sb = new StringBuilder();

        try
        {

            ProcessBuilder pb = new ProcessBuilder("C:\\Program Files\\SlikSvn\\bin\\svn status -u \"C:\\Projects\\\"");

            pb.redirectErrorStream(true);
            Process process = pb.start();
            BufferedReader inStreamReader = new BufferedReader(
                    new InputStreamReader(process.getInputStream()));

            while (process.isAlive() == true)
            {
                this.wait(3);
            }
            while (inStreamReader.ready() == true)
            {
                sb.append(inStreamReader.readLine());
            }

            System.out.println(sb.toString());
        }
        catch (IOException e1)
        {
            System.out.println("Es ist ein Fehler aufgetreten. " + e1.getMessage());
        }
        catch (Exception e)
        {
            System.out.println("Es ist ein Fehler aufgetreten. " + e.getMessage());
        }
        finally
        {
        }
    }

When I only execute this code, it will works.

ProcessBuilder pb = new ProcessBuilder("C:\\Program Files\\SlikSvn\\bin\\svn");

Answer 1

The solution is the comment from laune. The arguments have to stand in separate strings.

ProcessBuilder pb = new ProcessBuilder("C:\\Program Files\\SlikSvn\\bin\\svn", "status", "-u", "\"" +baseDir +"\"");

Answer 2

It's not C:\\\\Program Files\\\\SlikSvn\\\\bin\\\\svn . It's "C:\\\\Program Files\\\\SlikSvn\\\\bin\\\\svn.exe" . Note the extension and quotes around the path to the executable.
