error running javafx application with Intellij

I have a javafx program that I was formerly developing in sublime text before migrating to intellij as my editing environment. As of now, I can compile and run without error through the command line (Windows). However, when I try to run it from intellij, I get the following message:
Exception in Application start method

I don't know how to fix this.

The problem turned out to be intellij having an issue with the source folder in the project directory. By moving all my java files to a new directory and reopening it in intellij as a new project with a single, correct source folder, the problem completely went away.
(As stated in the question, the code itself was functional and worked through the command line.)

How can i solve this problem?

Check your OS that whether it is 32bit or 64bit.Then install the appropriate version opencv and javacv.

NPE caused by Modena.class.getResource("TestApp.css")

I'm trying to run the java-fx sample Modena that can be found here. I use Netbeans 8.0 Beta, JDK8 last release on Windows 8. I wonder why I can't even compile it.
In fact the first exception that happens is this.
I note to be a newbie in JavaFX.
The line of exception in the program is:
private static final String testAppCssUrl = Modena.class.getResource("TestApp.css").toExternalForm();
I assert that I verified and the file existed. And the example jar file can be run on my computer with my Java default configuration which is explained above.

The problem was with running only the main file with Shift+F6. I should have used F6 to run the project instead. F6 runs the project but Shift+F6 only runs the file containing the static main method without considering the project configuration.

What can I try?I've Googled this but haven't had much luck.

I don't know.When I use the Windows Version, I didn't meet any error;
Sounds like to me from your windows version has the missing class while your Linux Version does not.
Caused by: java.lang.ClassNotFoundException: junit.textui.ResultPrinter
Make sure you have this class in your library or where ever you are calling it for.
Hope this helps or points you to the right direction.
