IntelliJ簡體Hello World上的ClassNotFoundException

Question

即使在執行一個簡單的Hello World程序時，我正在使用IntelliJ，並且得到一個ClassNotFoundException異常。谷歌搜索後，看着how to add directory to classpath in an application run profile in intellij idea?，我試圖改變我的依賴到JDK文件夾（/Library/Java/JavaVirtualMachines/jdk1.7.0_10.jdk），並沒有用。

我也嘗試重新安裝JDK並重新安裝IntelliJ，但都無濟於事，我可以在NetBeans中運行程序而不會出現問題。這是怎麼回事？這是IntelliJ的一些奇怪的錯誤？

代碼：

public class AppMain { 

    public static void main(String[] args) { 
     System.out.println("Hello World!"); 
    } 
} 

錯誤：

我發現了什麼來分類的。這是我的導入設置的一個錯誤，刪除了我的首選項（即去〜/ Library/Preferences和rm -r IdeaIC13）。希望這對所有遇到此問題的人都有幫助。
