如何使用appium调用adb命令？

import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidElement;
import org.openqa.selenium.remote.DesiredCapabilities;

import java.net.MalformedURLException;
import java.net.URL;

public class AppiumADBExample {
    public static void main(String[] args) throws MalformedURLException {
        // 设置Desired Capabilities
        DesiredCapabilities caps = new DesiredCapabilities();
        caps.setCapability("platformName", "Android");
        caps.setCapability("deviceName", "设备名称");
        caps.setCapability("appPackage", "应用包名");
        caps.setCapability("appActivity", "应用启动Activity");

        // 初始化AndroidDriver
        AndroidDriver<AndroidElement> driver = new AndroidDriver<>(new URL("http://localhost:4723/wd/hub"), caps);

        // 调用adb命令
        driver.executeScript("adb shell <adb命令>");

        // 关闭驱动
        driver.quit();
    }
}
