How to run shell script in the plugin Follow

I have a need to run a shell script in the plugin , and I write the code like

public class ScriptRunner {
    public static void run(String script){
        try {
            Process process = Runtime.getRuntime().exec(new String[]{"/bin/sh", "-c", script});
            BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line = "\n running script : " + script + "\n";
            String currentLine;
            while ((currentLine = br.readLine()) != null) {
                line += currentLine + "\n";
            }
            PluginManager.getLogger().error(line);
            process.waitFor();
        } catch (Throwable e) {
            PluginManager.getLogger().error(e);
        }
    }
}

In the SandBox , it worked well , logger showed the whole executing process

But after plugin deployment, it did not execute the script . And I got nothing from the log which logger logged.

The script is like

lark2gitbook -t "xxxxxxxxxxx" -s xxxxxxx -o xxxxxx --public

My os is Mac os 10.13.5 

Idea version is '2018.2' 'Ultimate'

So, why did it not work in normal environment , and how can I fix it.

Thanks a lot
