问题描述

我正在尝试从LWJGL网站上运行示例"Hello World"

I'm trying to run the sample "Hello World" from the LWJGL website

通过此链接: LWJGL入门"

我正在尝试通过命令行执行此操作，只是为了让我更好地理解幕后".

I'm trying to do this via the command line, just so I understand the "behind the scenes" a bit better.

我已经成功地进行了编译，没有任何错误，但是当我尝试运行该程序时，却出现了此错误:

I've managed to compile without any errors, but when I try to run the program I'm getting this error:

C:\JavaProjects\LearningLWJGL>java -classpath .;./lib/*.jar -Djava.library.path=C:\Windows\System32 HelloWorld

推荐答案

CLASSCLASS条目是.class文件或.jar文件的包层次结构开头的目录.如果您期望./lib在该目录中包含所有.jar文件，则不会.您必须明确命名它们.

A CLASSPATH entry is either a directory at the head of a package hierarchy of .class files, or a .jar file. If you're expecting ./lib to include all the .jar files in that directory, it won't. You have to name them explicitly.
