对重复引用的评论：为什么在作为重复引用的问题之前的几年被问到这个问题时，这会被标记为重复？我也相信问题，细节和回答比引用的问题要好得多。

我做C++程序员已经有一段时间了，但我对Java很陌生，对Eclipse很陌生。我想使用触摸图“图形布局”代码来可视化我正在使用的一些数据。

此代码的组织方式如下：

如何在 Eclipse 中添加此项目并使其快速编译和运行？

答案 1

在 Eclipse 中创建一个新的 Java 项目。这将创建一个 src 文件夹（用于包含源文件）。
还要创建一个 lib 文件夹（名称并不重要，但它遵循标准约定）。
将文件夹复制到文件夹中（您可以使用操作系统执行此操作，而无需从Eclipse GUI进行任何花哨的导入或任何事情）。./com/*/src
将任何依赖项（您的项目本身所依赖的文件）复制到（请注意，这不应该包括 - 感谢评论者Mike Deck指出我对OP帖子的误解！jar/libTGGL jar)
将其他 TGGL 内容复制到根项目文件夹（或专用于需要在最终应用中分发的许可证的其他文件夹）
返回 Eclipse，选择您在步骤 1 中创建的项目，然后按 F5 键（这将刷新 Eclipse 的文件夹树视图，其中包含实际内容。
文件夹的内容将自动编译（类文件放置在 Eclipse 在创建项目时为您生成的 /bin 文件中）。如果您有依赖项（在当前项目中没有依赖项，但为了完整性，我将在此处包含依赖项），编译最初将失败，因为您缺少项目类路径中的依赖项 jar 文件。/src
最后，在 Eclipse 中打开每个必需的文件夹，然后选择构建路径。/libright clickjar fileBuild Path->Add
