libgdx - Intellij class not found exception?

Question

I am using intellij for the first time and I haven't been able to run any program. It builds without any errors or warnings but when I run, It throws the class not found exception. I have tried everything I could

Search on stack-overflow.
I've checked the source folder under the module setup.
I've checked the run configurations as well

but no luck.

Error:

Exception in thread "main" java.lang.ClassNotFoundException: com.nectarmicrosystems.libgdx.learning.desktop.DesktopLauncher
at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
at java.lang.ClassLoader.loadClass(ClassLoader.java:424)

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:122)

the class source:

package com.nectarmicrosystems.libgdx.learning.desktop;

import com.badlogic.gdx.backends.lwjgl.LwjglApplication;
import com.badlogic.gdx.backends.lwjgl.LwjglApplicationConfiguration;
import com.nectarmicrosystems.libgdx.learning.MyGdxGame;

public class DesktopLauncher {
    public static void main (String[] arg) {
        LwjglApplicationConfiguration config = new LwjglApplicationConfiguration();
        new LwjglApplication(new MyGdxGame(), config);
    }
}

dependencies

source structure

@TobiAdeyinka looks like intellij is picking wrong directory for `source Folder`. Post you directory structure as well — Bilal Shah, Dec 07 '15 at 15:14
@BilalShah i just added an image (source structure) is that what you mean? i cant post more than 2 links yet — conversation.16, Dec 07 '15 at 15:21
Add `src/main/java/` and make `java` folder as source folder and than try — Bilal Shah, Dec 07 '15 at 15:26

Thanks to every one that helped, I found the solution. basically the DesktopLauncher class was not getting compiled, so I ran the task through gradle this way:

look for the Gradle panel in the IDE, open desktop -> Tasks -> other and then double click on run.

you only need to do this the first time.

the run is its own launcher. this doesnt seem to fix the desktoplauncher not found error. – RichieHH Mar 10 '16 at 12:18

For people who are experiencing this problem, try selecting "desktop_main" in the "Use classpath of module:" drop-down list.

I was getting this error when I selected "desktop" as the module but the error went away when I selected "desktop_main."
