Question

编辑：已解决，请参阅评论

我正在尝试在LWJGL的网站（this one）上运行LWJGL 3的Hello World示例。我不会发布所有代码，因为我没有更改网站上的示例。我以为我在设置库时遵循了所有正确的步骤，但代码抛出以下错误打印输出：

Exception in thread "main" java.lang.ExceptionInInitializerError

    at org.lwjgl.glfw.GLFW.<clinit>(GLFW.java:659)
    ... 12 more

我在IntelliJ中运行它，并且我已将lwjgl，lwjgl-glfw，lwjgl-opengl和lwjgl-natives-windows.jar作为类添加到项目结构中。（如果我不添加lwjgl-natives-windows.jar，我会收到不同的错误消息。）

此错误的具体原因是什么？如何预防？我在本例中看到的其他问题没有与GLFWErrorCallback有关，我怀疑我可能做错了。

LWJGL Hello World示例抛出java.lang.ExceptionInInitializerError
