Unable to run the script written to test the Play store app - appium-android

Question

I am new to Appium and want to work on it. As a beginner I am trying to test the Play store application for which I have written the script in eclipse. I am trying to open the app and then click on the text box to write some text. When I am running the script, its only initiating the application and then nothing happens. Please find the code below.
package tests;
import java.net.MalformedURLException;
import java.net.URL;
import org.openqa.selenium.By;
import org.openqa.selenium.remote.DesiredCapabilities;
import io.appium.java_client.AppiumDriver;
import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;
public class AppiumTest {
public static void main(String[]args){
AppiumDriver<MobileElement> driver = null;
//Set the Desired Capabilities
DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability("deviceName", "Vinee");
caps.setCapability("udid", "3204d6dea76f219d");
caps.setCapability("platformName", "Android");
caps.setCapability("platformVersion", "5.1.1");
caps.setCapability("appPackage", "com.android.vending");
caps.setCapability("appActivity", "com.google.android.finsky.activities.MainActivity");
caps.setCapability("noReset", "true");
//Instantiate Appium Driver
try
{
driver = new AndroidDriver<MobileElement>(new URL("http://0.0.0.0:4723/wd/hub"),caps);
}
catch (MalformedURLException e)
{
System.out.println(e.getMessage());
}
//Find Google Play element using ID property and click on it
driver.findElement(By.id("com.android.vending:id/search_box_idle_text")).sendKeys("Calculator");
}
}
The error message I am getting is :

You can add the jar file containing the org/apache/commons/lang3/StringUtils at http://commons.apache.org/proper/commons-lang/download_lang.cgi.
Download the commons-lang3-3.7-src.zip under source and add to the project.
