I started to learn Spring Framework as my first ever app.I tried to get defined Beans count but i can't run it.

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;


public class runDemo {
    public static void main(String[] args) {
        ApplicationContext context = new AnnotationConfigApplicationContext();
        System.out.println(context.getBeanDefinitionCount());
    }
}

and my gradle file 

buildscript {
ext {
    springBootVersion = '1.5.6.RELEASE'
}
repositories {
    mavenCentral()
}
dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'

version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
mavenCentral()
}


dependencies {

compile('org.springframework.boot:spring-boot-starter')
testCompile('org.springframework.boot:spring-boot-starter-test')
}

and when i run this:

Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/context/ApplicationContext
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:264)
at com.intellij.rt.execution.application.AppMain.main(AppMain.java:123)
Caused by: java.lang.ClassNotFoundException: org.springframework.context.ApplicationContext ...

I have spring context and spring core in the External Libraries loaded.

EDIT:I upgraded to Intellij idea 2017.2 and it still give the same error

    Do you use an IDE? If this is your first ever app maybe start with something simpler? Like Hello World without Spring. – Oleg Aug 06 '17 at 17:45
  • i'm using java for two years ... im using intellij idea – SemyColon.Me Aug 06 '17 at 17:58
  • Ok, now we are getting somewhere. Because you wrote "Spring Framework as my first ever app" I thought that you just started programming. Check if [this](https://stackoverflow.com/questions/42587487/noclassdeffounderror-after-intellij-idea-upgrade) will help you. – Oleg Aug 06 '17 at 18:13
  • If you're using Java for 2 years, you should know better than naming your class like a method. Java class names conventionally begin with a capital letter. – Abhijit Sarkar Aug 06 '17 at 20:17

i replaced

compile('org.springframework.boot:spring-boot-starter')

compile('org.springframework.boot:spring-boot-starter-web')
