Jenkins Unable to start Appium Node

[supratimdutta]

Hi,
Currently when I run Appium using Jenkins , I see the following message:io.appium.java_client.service.local.InvalidServerInstanceException: Invalid server instance exception has occured: There is no installed nodes! Please install node via NPM (https://www.npmjs.com/package/appium#using-node-js) or download and install Appium app (http://appium.io/downloads.html)
at Test_Cases.Android.setUp(Android.java:37)
Caused by: java.io.IOException:
C:\windows\system32\config\systemprofile\AppData\Roaming\npm\node_modules

at Test_Cases.Android.setUp(Android.java:37)

I would like to understand how to explain Jenkins / Help Jenkins to run/ start my Appium Server

My Current Config:
Jenkins: 2.90
Appium Version: 1.7.1

Code to Start/ Stop the Appium Server:
public class AppiumServerJava {

private AppiumDriverLocalService service;
private AppiumServiceBuilder builder;
private DesiredCapabilities cap;

public void startServer() {
	//Set Capabilities
	cap = new DesiredCapabilities();
	cap.setCapability("noReset", "false");
	
	//Build the Appium service
	builder = new AppiumServiceBuilder();
	builder.withIPAddress("127.0.0.1");
	builder.usingPort(4723);
	builder.withCapabilities(cap);
	builder.withArgument(GeneralServerFlag.SESSION_OVERRIDE);
	builder.withArgument(GeneralServerFlag.LOG_LEVEL,"error");
	
	//Start the server with the builder
	service = AppiumDriverLocalService.buildService(builder);
	service.start();
}

public void stopServer() {
	service.stop();
}

public boolean checkIfServerIsRunnning(int port) {
	
	boolean isServerRunning = false;
	ServerSocket serverSocket;
	try {
		serverSocket = new ServerSocket(port);
		serverSocket.close();
	} catch (IOException e) {
		//If control comes here, then it means that the port is in use
		isServerRunning = true;
	} finally {
		serverSocket = null;
	}
	return isServerRunning;
}	



public static void main(String[] args) {
	AppiumServerJava appiumServer = new AppiumServerJava();
	
	int port = 4723;
	if(!appiumServer.checkIfServerIsRunnning(port)) {
		appiumServer.startServer();
		System.out.println("Server Started");
		
		appiumServer.stopServer();
		System.out.println("Server Stopped");
	} else {
		System.out.println("Appium Server already running on Port - " + port);
	}
}

}

I have the Appium installed as a node and works fine:
C:\Demo\Git_Repo\Netflix Demo>appium --version
1.7.1

Also, the Maven logs for success:
