Eclipse：使用本机打包 JAR
我使用LWJGL制作了一个Java游戏，这需要一些本机文件。在 Eclipse 中一切都运行良好。我想将 .dll 文件包含在 JAR 文件中，但每次我尝试时，LWJGL 都无法找到本机。我已经尝试过使用 jarsplice 或 fatjar，但没有成功。我知道我的世界也是使用 LWJGL 编程的，并且它以某种方式设法从另一个文件夹加载本机。
有没有办法将本机文件打包成 JAR 文件并让 3rd 方库（例如 LWJGL）访问它们？如果没有，我将如何从外部文件夹加载它们？
编辑：不知何故，它与 JAR 文件位于同一目录中的本机一起工作。不过，我仍然想要一些解释，也许还有其他一些方法。
I have made a Java game using LWJGL, which requires some native files. It all works fine in Eclipse. I want to include the .dll files inside a JAR file, but everytime I try, LWJGL can't find the natives. I have already tried using jarsplice or fatjar, but to no avail. I know minecraft is also programmed using LWJGL, and it somehow manages to load the natives from another folder.
Is there a way to package native files into a JAR file and let a 3rd party library, like LWJGL access them? If not, how would I approach loading them from an external folder?
EDIT: Somehow it worked with the natives in the same directory as the JAR file. I would still like some explanation and perhaps some other methods, though.

我几周前才遇到这个问题。唉，我没有链接，但我发现您无法引用存储在 jar 文件内的本机文件。您必须在引用它们之前以编程方式提取它们，或者必须将它们与 jar 文件一起安装。
我选择了第二个选项，让 Eclipse 将整个集合打包到一个 zip 文件中进行分发。
对于第一个选项，可以查看 JNA 的源代码。他们将 dll/二进制文件放入其 jar 文件中，然后根据需要进行提取。
I just ran into this a few weeks ago. Alas, I do not have links, but I found that you cannot reference native files stored inside of a jar file. You have to either programatically extract them before you reference them, or you have to install them alongside your jar file.
I went with the second option and just have Eclipse pack the whole collection into a zip file for distribution.
For the first option, one place to look would be the source code for JNA. They ship dll's/binaries inside their jar file and extract then on demand.
