AppleScript 命令在终端中有效，但在 Java 中无效

Question

My main question is how can I make the command mentioned below work in java, The main problem in this command is it does not do script that I commanded it to execute; can someone help me make this apple script work in java?

I do not understand but for some reason the command:

osascript -e 'tell application "Terminal" to do script "cd /Users/benjaminsloutsky/eclipse-workspace/stack/Stack/StackProjects/Brother/build && cmake.. && cmake --build. &&./cmake-good"'

executes in the terminal, but whenever I try to run it in java using Runtime.getRuntime().exec() command it does not execute at all (it does not show me a new terminal window with code being execucted, but works in terminal). The whole point of this command is to show a new terminal with the output of the main.cpp file. This is my java code:

final String innerCommand = 
     "cd /Users/benjaminsloutsky/eclipse-workspace/stack/Stack/StackProjects/Brother/build && cmake .. && cmake --build . && ./cmake-good";
String[] comm = new String[] {
     "/bin/bash", "-c", 
     "osascript -e 'tell application \"Terminal\" to do script \"" +
     innerCommand + "\"'"
};
Runtime.getRuntime().exec(comm);

it does not run. Why is that and how could I fix this issue so my script could also run in javafx. The point of this command is to show a new terminal window and then run a script.

I thought that I am running multiple commands correctly as listed in my comm variable and I am executing the command with runtime.

Thank you in advance!

Runtime.getRuntime().exec() is not the best way to run and manage the external processes in Java, its better to use the java.lang.ProcessBuilder instead.

So your code can be expressed in java.lang.ProcessBuilder like this.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.TimeUnit;

public class CommandExecutor {

    public static void main(String[] args) {
        CommandExecutor executor = new CommandExecutor();
        executor.executeInTerminal("cd /Users/benjaminsloutsky/eclipse-workspace/stack/Stack/StackProjects/Brother/build && cmake .. && cmake --build . && ./cmake-good");
    }

    public void executeInTerminal(String command){
        List<String> cms = new ArrayList<>();
        cms.add("/bin/sh");
        cms.add("-c");
        cms.add("osascript -e 'tell application \"Terminal\" to do script \"" + command + "\"'");

        ProcessBuilder processBuilder = new ProcessBuilder();
        processBuilder.command(cms);
        try {

            Process process = processBuilder.start();

            StringBuilder output = new StringBuilder();

            BufferedReader reader = new BufferedReader(
                new InputStreamReader(process.getInputStream()));

             String line;
             while ((line = reader.readLine()) != null) {
                output.append(line + "\n");
            }

            boolean success = process.waitFor(1, TimeUnit.MINUTES);
            // check the status
        } catch (IOException | InterruptedException e) {
            // do some logging
        }
    }
}
