我从here下载了jogl 2.0，文件jogl-all.jar，并运行了一个来自here的简单代码示例：

我得到了：
The import javax.media.opengl.GLCanvas cannot be resolved
The import com.sun.opengl cannot be resolved
还有一些（来自其他项目）：
Texture cannot be resolved to a type
Animator cannot be resolved to a type
我猜jar不支持那些类型，为什么呢？这有什么办法吗？
这很奇怪，因为2.0版本假设支持版本1.0支持的所有内容，或者我错了？
此外，此代码适用于jogl 1.0，但我必须使用2.0版。
答案 0 :(得分：4)
在jogl 1.1和2.0之间，jogl项目的顶级包名称从javax.media.opengl更改为com.jogamp.opengl
对于列出的两个案例，Animator类现在可以在com.jogamp.opengl.util.Animator下找到，而Texture现在位于包com.jogamp.opengl.util.texture.Texture
jogl的javadoc应该有助于找到你缺少的任何其他类。 https://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/
