java - 将带有处理元素的java程序导出到可执行jar

Question

我有一个带有处理元素的 java 项目，可以在 Eclipse 中编译并正常运行，但我需要将其导出为可执行文件。当我通过 Eclipse 的导出向导执行此操作时，它会生成一个 jar，但是当双击或从命令行调用该 jar 时，会产生运行时错误。首先它给了我这个:

所以我尝试将gluegen-rt.dll粘贴到给定的目录中，然后它给了我这个错误:

经过一番谷歌搜索后，看来这个依赖问题可能是 jogl 的一个错误:https://java.net/jira/browse/JOGL-346但我很难相信没有人能够从 Eclipse 导出任何处理应用程序。一定有办法，不是吗？

有什么建议吗？

Answer 1

处理需要 native 库，但您似乎没有包含该库。您至少需要为您所在的系统放置 JOGL jar，但这不会帮助您部署到其他系统。

无耻的 self 推销:我编写了一个工具，可以帮助您创建自解压的可运行 jar 文件，自动处理处理的 native 库，因此它可以在每个系统上运行:http://StaticVoidGames.com/SvgExe/
