如何将预先存在的Java项目导入Eclipse并启动并运行？

Question

对重复参考的评论：为什么在被问为重复的问题之前多年被问到时，为什么将其标记为重复？ 我还认为问题，细节和响应比所提到的问题要好得多。

我已经成为C
++程序员已有一段时间了，但是我是Java和Eclipse的新手。我想使用触摸图“图形布局”代码来可视化我正在使用的某些数据。

这段代码是这样组织的：

如何在Eclipse中添加此项目并使其快速编译和运行？

Answer 1

1. 在Eclipse中创建一个新的Java项目。这将创建一个src文件夹（以包含您的源文件）。

2. 还要创建一个lib文件夹（名称不是那么重要，但是遵循标准约定）。

3. 将./com/*文件夹复制到文件/src夹中（您可以使用OS进行此操作，而无需执行任何高级导入操作或从Eclipse GUI中执行任何操作）。

4. 将所有依赖项（jar项目本身依赖的文件）复制到/lib（请注意，其中 不应 包含TGGL jar- 感谢评论者Mike Deck指出了我对OP帖子的误解！ ）

5. 将其他TGGL内容复制到根项目文件夹（或其他一些专用于许可证的文件夹，您需要在最终应用程序中分发这些许可证）

6. 返回Eclipse，选择在步骤1中创建的项目，然后按F5键（这将刷新Eclipse的文件夹树视图，并包含实际内容。

7. /src文件夹的内容将自动编译（将类文件放置在Eclipse在创建项目时为您生成的/ bin文件中）。 如果您有依赖项 （您不在当前项目中，但出于完整性考虑，我将在此包括在内）， 则编译最初会失败，因为您缺少jar files项目类路径中的依赖项。

8. 最后，根据需要/lib在Eclipse中打开文件夹，然后选择构建路径。right click``jar file``Build Path->Add

这会将特定的jar添加到项目的类路径中。Eclipse将检测到更改并自动编译之前失败的类，现在您应该拥有一个包含您的应用程序的Eclipse项目。
