Unable to run a TestNG with Gradle

I have a simple code which runs with TestNG, but I am unable to run the same with Gradle, as it says no main method is found, which is, well, not surprising since I am using annotations.

But in such a scenario, how to run the code if I must use Gradle.

Kindly note, I am very new to Gradle, and do not harbour much knowledge about the same.

Code:

import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

public class tryTestNG
{
    @BeforeClass
    public void setup()
    {
        System.out.println("I am in Setup");
    }

    @Test
    public void test()
    {
        System.out.println("I am in Test");
    }

    @AfterClass
    public void tearDown()
    {
        System.out.println("I am in tearDown");
    }
}

The above code runs perfectly with TestNG Library. However not with Gradle.

Here is my Gradle Build setup:

apply plugin: 'java'
apply plugin: 'application'

mainClassName = 'tryTestNG'
sourceCompatibility = 1.7
targetCompatibility = 1.7
version = '1.0'

repositories {
    mavenCentral()
}

test {
    useTestNG()
}


dependencies {
    compile group: 'org.testng', name: 'testng', version: '6.9.10'        
}

The Gradle returns that there is no Main Method.

Thanks for your help.

There's no need to use application plugin to run tests.

The build.gradle should be:

apply plugin: 'java'

sourceCompatibility = 1.7
targetCompatibility = 1.7
version = '1.0'

repositories {
    mavenCentral()
}

test {
    useTestNG()
}


dependencies {
    compile group: 'org.testng', name: 'testng', version: '6.9.10'
}

And the command: gradle test. Also, put tryTestNG under src/test/java and name it with capital letter.

Here is a demo.

Also mind that println statements from tests won't be visible in console. To view them navigate to test report. It's under: <project_dir>/build/reports/tests/index.html.
