Question

Dev env：ItelliJ 14 - ＆gt;编译并运行良好。

从命令行执行我自定义创建的.jar时会出现

C:\Java\Projects\OpenGLES\out\artifacts\Test1>java -jar Test1.jar
Exception in thread "main" java.lang.NoClassDefFoundError: com/jogamp/opengl/G

我试图创建.jar工件，我可以双击启动。我认为这个问题意味着这个类找不到一些资源。 JOGL / JogAmp官方网站给出了使用JOGL部署.jars的说明，但我认为我错过了一些东西。

Test1.jar具有以下结构：

Test1.jar/
--com/
----company/
------Main.class
--jar/
----gluegen-rt.jar
----gluegen-rt-natives-windows-amd64.jar
----gluegen-rt-natives-windows-i586.jar
----jogl-all.jar
----jogl-all-natives-windows-amd64.jar
----jogl-all-natives-windows-i586.jar
--lib/
----windows-amd64/
-------gluegen-rt.dll
-------joal.dll
-------jocl.dll
-------jogl_cg.dll
-------jogl_deskop.dll
-------jogl_mobile.dll
-------nativewindow_awt.dll
-------nativewindow_win32.dll
-------newt.dll
-------soft_oal.dll
--META-INF/
----MANIFEST.MF
--com
--jar
--lib
--META-INF

manifest.mf包含 -

Manifest-Version: 1.0
Main-Class: com.company.Main

通过堆栈跟踪，似乎JVM找不到类com.jogamp.opengl.GLEventListener，这意味着它无法解析包含的jar文件的路径。 jar文件的路径不正确。点击链接查看如何正确包装罐子。
