Java libgdx源代码生成错误无法解析为类型

我在设置Libgdx源代码时遇到问题，我遵循了以下两个设置指南：

我已经下载了源代码，安装了最新版本的JDK，安装了适用于Android 25的Android SDK，并完成了所有其他步骤（据我所知是正确的），但我的libgdx设置上有数千个错误，即使在我尝试清理和重建时也是如此。错误都是“无法解析为类型”。有人知道我把哪一步弄糟了吗

另外，我试着运行“ant”，他们忘记在运行演示页面中提到，但这仍然没有解决问题

可能是我使用的是Java8JDK，而libgdx仍然使用Java7吗

您是否在java构建路径中添加了必需的.jars文件

---

通过右键单击项目，在Eclipse中添加所需的JAR→ 构建路径→ 配置生成路径。在“库”选项卡下，单击“添加Jar”或“添加外部Jar”并提供Jar。

请显示您的错误日志，并确保您正在使用eclipse运行演示和测试。我已经添加了一些当前存在的编译错误，如果您认为有帮助，我还可以尝试运行其中一个演示。我正在使用eclipse。啊，谢谢。我必须将哪些JAR添加到构建路径？dist文件夹中的所有内容？eclipse中安装的所有GWT importsIs GWT SDK和插件似乎都有问题？否，然后将其安装到GWT Deployment中，您可以在其中找到dist文件夹。我不知道什么是dist文件夹，里面有什么？你添加了gdx-backend-gwt-1.9.5.jar吗，版本可能会有所不同？
