Description

HI, Im facing this issue of starting appium server programatically. I have gone through many other github threads about this same issue but to no luck.

Environment

Appium version: 1.21.0 (latest)

Node: v12.19.0

Details

I am calling the service on rest template. I tried many ways of starting an appium server programmatically but non worked. Please help

Code To Reproduce Issue

public class AppiumServer {

private static AppiumDriverLocalService server;
private int port;

public AppiumServer() {
   server =  buildAppiumServer();
}

private AppiumDriverLocalService buildAppiumServer() {
    return new AppiumServiceBuilder().usingAnyFreePort()
            .withIPAddress( "127.0.0.1" )
            .withArgument( GeneralServerFlag.LOG_LEVEL, "error" )
            .withArgument( GeneralServerFlag.SESSION_OVERRIDE )
            .build();
}

public void start(){

    this.server.start();
}

public void stop() {
    this.server.stop();
}

public AppiumDriverLocalService get(){
    return this.server;
}

}

What's the output when you run the command manually?

KazuCocoa commented 3 years ago

Perhaps loglevel info/debug helps at first.

RehanProgrammer commented 3 years ago

when i run the command "node /usr/local/lib/node_modules/appium/build/lib/main.js", appium starts on terminal. My node executable path is /usr/local/bin/node

RehanProgrammer commented 3 years ago

Also my appium is installed globally via "npm i -g appium". On terminal, i can start the appium by running "appium". I am using jdk 11 in this case. I have also given read, write, execute permission to both directories

KazuCocoa commented 3 years ago

What about running the server like tests https://github.com/appium/java-client/blob/0e05078d0ae8e4bebb80080790712e933e2ea666/src/test/java/io/appium/java_client/android/BaseAndroidTest.java#L40 ?

RehanProgrammer commented 3 years ago

I would like to start appium programmatically on a specific port. Is there anyway i can do that like the example above. I am developing an application which needs to start appium

                **.withTimeout(Duration.ofSeconds(300))**
                .build();
        service.start();

Try adding timeout

drjoeyoussef commented 1 year ago

I have the same issue, did anyone find a solution for it?

I'm getting this error:

io.appium.java_client.service.local.AppiumServerHasNotBeenStartedLocallyException: The local appium server has not been started. The given Node.js executable: /usr/local/bin/node Arguments: [/usr/local/lib/node_modules/appium/build/lib/main.js, --port, 4723, --address, 0.0.0.0] Process output: [Appium]spawn npm ENOENT

Krishna077 commented 1 year ago

@drjoeyoussef try adding withTimeout(Duration.ofSeconds(200)) in your AppiumServiceBuilder(). It should do the trick

drjoeyoussef commented 1 year ago

@Krishna077 Thank you for reply dear! I actually tried it but it's not working on the mac, I've been told that there is no solution for the mac for now, I don't know if you've tried it also on a mac.

Krishna077 commented 1 year ago

@drjoeyoussef Yes I tried it on my Mac. Can you share your builder method?

drjoeyoussef commented 1 year ago

@Krishna077 I really appreciate your kindness and your help. That's the builder method: 

public IOSDriver driver;
public AppiumDriverLocalService service;
@BeforeClass
    public void ConfigureAppium() throws MalformedURLException
{
service = new AppiumServiceBuilder().withAppiumJS(new File("//usr//local//lib//node_modules//appium//build//lib//main.js"))
                .withIPAddress("0.0.0.0").usingPort(4723). withTimeout(Duration.ofSeconds(200)).build();

service.start();

}
Krishna077 commented 1 year ago

@drjoeyoussef AppiumJS path doesn’t look right. Could you check your path , you might need to remove extra / from the path and you have an extra space before your timeout

drjoeyoussef commented 1 year ago

@Krishna077

I tried it like that 

service = new AppiumServiceBuilder().withAppiumJS(new File("/usr/local/lib/node_modules/appium/build/lib/main.js"))
                .withIPAddress("0.0.0.0").usingPort(4723).withTimeout(Duration.ofSeconds(200)).build();

        service.start();

I got the same error:

Can you try the below : service = AppiumDriverLocalService.buildService(new AppiumServiceBuilder().withIPAddress("0.0.0.0").usingPort(Integer.parseInt("4723")).withTimeout(Duration.ofSeconds(200)).withAppiumJS(new File("/usr/local/lib/node_modules/appium/build/lib/main.js")));

service.start();

RucheeSadani commented 1 year ago

I am also facing the same issue since yesterday before that it was working fine. Below is the code snippet that I have written AppiumDriverLocalService service = new AppiumServiceBuilder().withAppiumJS(new File("//usr//local//lib//node_modules//appium//build//lib//main.js")) .withIPAddress("127.0.0.1").usingPort(4723).build(); service.start(); //Create object of Android driver UiAutomator2Options options = new UiAutomator2Options();

And below is the error :

"io.appium.java_client.service.local.AppiumServerHasNotBeenStartedLocallyException: The local appium server has not been started. The given Node.js executable: /usr/local/bin/node Arguments: [/usr/local/lib/node_modules/appium/build/lib/main.js, --port, 4723, --address, 127.0.0.1] Process output: [Appium] spawn npm ENOENT"

Can someone please help me
