jar包里执行shell脚本

jar包想执行一个shell脚本，用到ProcessBuilder,发现把死活执行不了,刚开始是路径不对，最后调整完路径之后发现jar包根本无法找到对应的资源文件.如下:

error1:Cannot run program "./runJar11.sh" (in directory "file:/Users/songxuhua/Documents/MonkeyDev自动化安装/libWebsocket.jar!/assets"): error=2, No such file or directory

最后只能将jar包和sh脚本放在同一个文件夹下,获取jar所在文件夹目录(不包括jar)

    path = System.getProperty("user.dir");

完整代码如下

   ProcessBuilder pb = new ProcessBuilder("./runJar11.sh");
   String path = System.getProperty("user.dir");
    pb.directory(new File(path));
    int runningStatus = 0;
    String s = null;

    try {
        Process p = pb.start();
        BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
        BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
        while ((s = stdInput.readLine()) != null) {
            System.out.println("s is " + s);
        }
        while ((s = stdError.readLine()) != null) {
            System.out.println("s is" + s);
        }
        try {
            runningStatus = p.waitFor();
        } catch (InterruptedException e) {
            System.out.println("error:" + e.getLocalizedMessage());
        }

    } catch (IOException e) {
        System.out.println("error1:" + e.getLocalizedMessage());

    }
    if (runningStatus != 0) {

    }
    return;
}
