从Java运行Ruby脚本

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class RunRubyScript {
    public static void main(String[] args) {
        try {
            // 构建命令行
            ProcessBuilder pb = new ProcessBuilder("jruby", "script.rb");
            pb.redirectErrorStream(true);
            
            // 执行命令行并获取输出
            Process process = pb.start();
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
            
            // 等待命令行执行完成
            int exitCode = process.waitFor();
            System.out.println("Exit Code: " + exitCode);
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
