最近我开始了解这个很棒的框架，即 Libgdx。我对这个框架完全陌生，因此一些障碍是显而易见的。我已经克隆了整个存储库，并且还运行了 gdx-setup-ui.jar 文件。它给了我 4 个基本的入门项目。(my-gdx-game, my-gdx-game-android, my-gdx-game-desktop, my-gdx-game-html) android 和桌面项目运行良好，但是，当我尝试运行 HTML5 项目时，点击 URL 链接后，我遇到了这个错误，

目前我使用的是 libgdx 0.9.7 版。我的操作系统是 Ubuntu 12，Eclipse Indigo。请帮帮我。谢谢。
