Adding a source folder directly, rather than its contents

Typically, you'll have a source structure like so: "src/package/path/MyClass.java". When you add src to the list of sources, it will include the contents, e.g. package.path.MyClass. That is sensible.

There is a project I'm working on that has a resource folder which I'd like to add directly. E.g. Add the folder itself, not the folder's contents. For example, suppose I have structure: "images/img.png". Currently, if I add images to sources, then img.png gets copied directly to the build directory, instead of images/img.png. As a workaround, I have to rearrange the structure to be something like "src_images/images/img.png", or move into "src/images/img.png". Hope that makes sense.

该 issue 未指定实现文件或测试。首先找到扩展处理已配置源文件夹的代码，并复现 images/img.png 示例；当添加 images 后，该文件夹会保留在构建输出中，同时现有的 source-package 行为保持不变时，即表示完成。
