問題描述
libgdx ‑ Intellij 類未找到異常？ (libgdx ‑ Intellij class not found exception?)
我是第一次使用 intellij，但我無法運行任何程序。它構建時沒有任何錯誤或警告，但是當我運行時，它會拋出 class not found 異常。我已經盡我所能
- 在 stack‑overflow 上搜索。
- 我已經檢查了模塊設置下的源文件夾。
- 我'我也檢查了運行配置
但沒有運氣。
錯誤：

參考解法
方法 1:
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.
方法 2:
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."
