我正在尝试为Java中的流程构建器设置PATH环境变量，我尝试了以下操作：

ProcessBuilder pb = new ProcessBuilder(command);
Map<String,String> mp = pb.environment();
mp.put("Path","myPath");
pb.start();

但是以下操作无效，流程构建器选择了默认系统路径。

我有一个Java应用程序，用于ProcessBuilder准备操作系统命令并给我一个Process对象。（实际的os命令是使用cygwin在ssh上进行rsync的）。

这在Windows中运行良好，但是，如果我想停止使用process.destroy()它的进程将不会杀死子ssh和rsync进程……..我必须使用Windows任务管理器手动将其杀死。

是否有可能OutputStream在我打电话之前以某种方式获取该进程的信息并发送ctrl-c destroy();？

如果有人对解决方法有任何想法，那就太好了。感谢：D
