Comment

//To run the class name from command line using gradle run
mainClassName = 'com.sam.home.HelloWorld'

//To create a runnable jar  in GradleJavaProject\build\libs then java -jar GradleJavaProject.jar
jar {
    manifest {
        attributes 'Main-Class': 'com.sam.home.HelloWorld'
    }
}

//Alternatively you can run it as a task too gradle -q  runWithJavaExec
task runWithJavaExec(type: JavaExec) {
    group = "Execution"
    description = "Run the main class with JavaExecTask"
    classpath = sourceSets.main.runtimeClasspath
    main = 'com.sam.home.HelloWorld'
}
