Start & Stop Appium Server Programmatically using Java (MAC OSX)

AppiumServer.java

package utilities;

import org.apache.commons.exec.CommandLine;
import org.apache.commons.exec.DefaultExecuteResultHandler;
import org.apache.commons.exec.DefaultExecutor;
import java.io.IOException;

		command.addArgument(
				"/Applications/Appium.app/Contents/Resources/node_modules/appium/bin/appium.js",

}

The start and stop methods are good to go with if we have only one instance of appium server. What if we have multiple appium server launched and we want to stop a particular node. using given code to stop server stops all the servers launched.

welcome your suggestions...

I'm also having same question, what we can do if we have 2 appium server instance. @benz-philip

When tried to run the above code :
@Test(enabled = true)
public void startServer() {

	CommandLine command = new CommandLine("/Applications/Appium.app/Contents/Resources/node/bin/node");
	command.addArgument("/Applications/Appium.app/Contents/Resources/node_modules/appium/lib/appium.js", false);
	command.addArgument("--address", false);
	command.addArgument("127.0.0.1");
	command.addArgument("--port", false);
	command.addArgument("4723");
	command.addArgument("--full-reset", false);
	DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();
	DefaultExecutor executor = new DefaultExecutor();
	executor.setExitValue(1);
	try {
		executor.execute(command, resultHandler);
		Thread.sleep(5000);
		System.out.println("Appium server started.");
	} catch (IOException e) {
		e.printStackTrace();
	} catch (InterruptedException e) {
		e.printStackTrace();
	}
}

@Test(enabled = false)
public void stopServer() {
	String[] command = { "/usr/bin/killall", "-KILL", "node" };
	try {
		Runtime.getRuntime().exec(command);
		System.out.println("Appium server stopped.");
	} catch (IOException e) {
		e.printStackTrace();
	}
}

}`

I got the following error :

/Applications/Appium.app/Contents/Resources/node_modules/appium/lib/appium.js:1
(function (exports, require, module, __filename, __dirname) { import _ from 'lodash';
^^^^^^

After running the code :
Got the following message :
Default test
Tests run: 1, Failures: 0, Skips: 0
So the test ran successfully , but after trying to find if any server is working on port 4723 , using
netstat -vanp tcp | grep 4723 , i got no process running on the port.

Can anyone help me with this? TIA :)

Getting connection refused :(

Connection get refused when your specified port is already occupied!
If you try to stop thread running using that port will resolve your problem or if you could change your port itself.
