Unable to run Appium server programmatically

[saikrishna321]

@TikhomirovSergey as you suggested in the previous post i have my node set in Mac OSX path

➜ AppiumParallel git:(master) ✗ node --version
v0.12.7

echo $PATH
/Users/saikrisv/Library/Android/sdk/platform-tools:/Users/saikrisv/Library/Android/sdk/tools:/Users/saikrisv/Library/Android/sdk/platform-tools:/Users/saikrisv/Library/Android/sdk/tools:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

I able to run node command from any path from ma commandline. Below is the code i use to start the server

AppiumServiceBuilder builder = new AppiumServiceBuilder().withAppiumJS(new File("/usr/local/lib/node_modules/appium/bin/appium.js"))
.withArgument(GeneralServerFlag.APP,
System.getProperty("user.dir") + "/build/wordpress.apk")
.withArgument(GeneralServerFlag.LOG_LEVEL, "info").usingAnyFreePort(); /and so on/;
AppiumDriverLocalService service = builder.build();
service.start();

Error :::

Hi @saikrishna321
There is really interesting situation

Are you starting it from the Eclipse for Mac OS?

This code works when I start it from IntelijIDEA/Eclipse for Windows (7&8). When I do the same from IntelijIDEA/Eclipse for Mac OS X it works with IntelijIDEA (I use v14.x).

With Eclipse for Mac OS I catch the same exception (!!!).

So I have two concerns:

• the first is there is a bug of java_client. So we have to get it fixed.
• the second is there is a bug of Eclipse for Mac OS. With the Eclipse for Windows it works (!!!). Maybe there are some settings that should be defined.

@saikrishna321 If you know which settings should be defined please post them here. Also I recommend you to use IntelijIDEA till the root cause is found or use the following method:

service.withDriverExecutable

Anyway everything should work with Maven started from a command line.

[TikhomirovSergey]

It is the problem of Eclipse for Mac OS. As soon as possible I'll post the way to resolve the problem

[TikhomirovSergey]

@saikrishna321
So
As I've mentioned it is the problem of Eclipse IDE (for Mac OS, it is probably for Linux too). Links:

• Eclipse not using PATH
• Is there a way to execute a linux command from Eclipse. StackOverflow
• Java Runtime command line Process. StackOverflow

... and tons of information that Google can find.

Actually I've tried some of these solutions:

1. These fails

1. Then I made a simple configuration

This value was copied from output of

echo $PATH

1. Then it started to work

The same works with this samples.

So I can advice you a few ways to resolve your problem with the test debugging:

1. To configure Eclipse IDE/current project workspace properly

2. To use IntellijIDEA instead of Eclipse

3. To not do something special and set a full path to the certain Node.js instance

   service.withDriverExecutable

@saikrishna321 I'm waiting for your response. If you are agree then I'll close this ticket. Please provide some more details or describe your ideas otherwise.

[saikrishna321]

@TikhomirovSergey Thanks a lot for all the details and helping me out resolve this issue.

1. Setting ANDROID_HOME and PATH into Eclipse environment, helped me debug the code.
2. Running the code from Intellij, had no issues.

Is possible to set different bootstrap-port, the way we set appium_port ?

new AppiumServiceBuilder().
usingPort(4000);

[TikhomirovSergey]

@saikrishna321 Yep

new AppiumServiceBuilder().
withArgument(AndroidServerFlag.BOOTSTRAP_PORT_NUMBER,"Your port number");

Then I'll close this issue. Actually I haven't known about this special thing of Eclipse IDE too :). Thanks! This ticket is marked by lables and information won't be lost.

[pr4bh4sh]

The issue is marked closed now however i have the solution which works perfectly for me without using any configuration in eclipse at all.
I have cooked something using the below link prior to the autolaunch introduced in Java client itself.
http://stackoverflow.com/questions/20922600/execute-adb-command-from-java-program

public class Utils {
    private static final String[] WIN_RUNTIME = { "cmd.exe", "/C" };
    private static final String[] OS_LINUX_RUNTIME = { "/bin/bash", "-l", "-c" };

    private Utils() {
    }

    private static <T> T[] concat(T[] first, T[] second) {
        T[] result = Arrays.copyOf(first, first.length + second.length);
        System.arraycopy(second, 0, result, first.length, second.length);
        return result;
    }

    public static List<String> runProcess(boolean isWin, String... command) {
        System.out.print("command to run: ");
        for (String s : command) {
            System.out.print(s);
        }
        System.out.print("\n");
        String[] allCommand = null;
        try {
            if (isWin) {
                allCommand = concat(WIN_RUNTIME, command);
            } else {
                allCommand = concat(OS_LINUX_RUNTIME, command);
            }
            ProcessBuilder pb = new ProcessBuilder(allCommand);
            pb.redirectErrorStream(true);
            Process p = pb.start();
            p.waitFor();
            BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
            String _temp = null;
            List<String> line = new ArrayList<String>();
            while ((_temp = in.readLine()) != null) {
                System.out.println("temp line: " + _temp);
                line.add(_temp);
            }
            System.out.println("result after command: " + line);
            return line;

        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
}

@TikhomirovSergey it would be time saver if this could be integrated with java client.
