不能运行程序 "cmd"：error=2，没有这样的文件或目录。

Question

这是我的java代码。

import java.io.IOException;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

@RestController
class HelloController {
    @GetMapping("/")
    public String testJob() {
        String path="cmd /c start C:\\myfile.bat";

         try
          {
               Runtime.getRuntime().exec(path);
          } catch (IOException e) {
                return e.getMessage();
          }

        return "Done";
    }
} 

当我运行它时，它工作得很好，但在heroku部署后，我得到了这个错误。

Cannot run program "cmd": error=2, No such file or directory

有什么建议吗？

这是我的新代码

package com.example.demo;

import local_project.addcase_0_1.addCase;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);

    }
}
@RestController
class HelloController {
    @GetMapping("/")
    public String TestJob() {
        addCase a = new addCase();
        a.runJob(new String[] {});   
        return "Added";
    }
}

我试图在java代码中运行一个talend作业！我按照这些说明做了 https:/help.talend.comreaderLod~TDRaNw2L2VZKV9XgZwty4l9kEdDoVHlHIAOW1e~Q][1] 。 当我运行它时，它工作得很完美，但我不能在heroku上部署它。
