How to resolve this JNI error when trying to run LWJGL "Hello World"?
提问by yoonsi
I'm trying to run the sample "Hello World" from the LWJGL website
我正在尝试从 LWJGL 网站运行示例“Hello World”
From this link: LWJGL "Getting Started"
来自此链接：LWJGL“入门”
I'm trying to do this via the command line, just so I understand the "behind the scenes" a bit better.
我试图通过命令行来做到这一点，只是为了让我更好地理解“幕后”。
I've managed to compile without any errors, but when I try to run the program I'm getting this error:
我设法编译没有任何错误，但是当我尝试运行该程序时，出现此错误：
C:\JavaProjects\LearningLWJGL>java -classpath .;./lib/*.jar -Djava.library.path=C:\Windows\System32 HelloWorld

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 ./libto include all the .jar files in that directory, it won't. You have to name them explicitly.
CLASSPATH 条目要么是位于 .class 文件包层次结构头部的目录，要么是 .jar 文件。如果您希望./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。

I had same issue using different dependancy what helped me is to set scope to compile.
我在使用不同的依赖时遇到了同样的问题，帮助我的是设置编译范围。
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>compile</scope>
</dependency>
