libgdx源代碼生成錯誤無法解析到我無法建立Libgdx源代碼類型

Question

，我跟着這兩個設置指南： https://github.com/libgdx/libgdx/wiki/Setting-up-your-Development-Environment-%28Eclipse%2C-Intellij-IDEA%2C-NetBeans%29

https://github.com/libgdx/libgdx/wiki/Running-demos-%26-tests

我已經下載了源代碼，擁有最新版本的JDK，擁有安裝了Android 25的Android SDK，並完成了所有其他步驟（據我所知，正確），但是我的libgdx安裝程序有成千上萬的錯誤，即使我嘗試清潔和重建。這些錯誤都是「無法解析爲某種類型」的。任何人都知道我可能弄錯了什麼？

此外，我嘗試運行「螞蟻」，他們忘了在正在運行的演示頁面中提到，但仍然沒有解決問題。

難道是因爲我在使用Java 8 JDK，而libgdx仍然在Java 7上？

您是否在java構建路徑中添加了需要的.jars文件。

右鍵單擊項目→構建路徑→配置構建路徑，在Eclipse中添加所需的jar。在Libraries選項卡下，單擊Add Jrs或添加外部JAR並提供Jar。
