Baseclass核心代码

AppiumDriverLocalService service;

public void appiumStart(){
        service = new AppiumServiceBuilder().withAppiumJS(new File("//usr//local//lib//node_modules//appium//build//lib//main.js")).withIPAddress("127.0.0.1").usingPort(4724).build();
        service.start();
}

异常触发代码行

service = new AppiumServiceBuilder().withAppiumJS(new File("//usr//local//lib//node_modules//appium//build//lib//main.js")).withIPAddress("127.0.0.1").usingPort(4724).build();
