I am trying to launch appium service through this code

 service = new AppiumServiceBuilder()
	                   .usingDriverExecutable(new File("C:/Program Files/nodejs/node.exe"))
	                   .withAppiumJS(new File("C:/Program Files (x86)/Appium/node_modules/appium/bin/appium.js"))
	                   .withLogFile(new File("./AppiumLogs.txt"))
	                   .withIPAddress("127.0.0.2")
	                   .usingPort(4925);
	service.build().start();
