Java -系统在使用ProcessBuilder目录时找不到指定的文件()

import java.io.IOException;

public class ProcessBuilderExample {
    public static void main(String[] args) {
        try {
            ProcessBuilder processBuilder = new ProcessBuilder("command", "arg1", "arg2");
            processBuilder.directory(new File("path/to/directory"));
            Process process = processBuilder.start();

            // 处理进程的输出流和错误流
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            // 等待进程执行完成
            int exitCode = process.waitFor();
            System.out.println("Exit Code: " + exitCode);
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
