在 Intellij Idea 中运行 LWJGL 应用程序答案

【问题标题】：Running LWJGL application within Intellij Idea在 Intellij Idea 中运行 LWJGL 应用程序

【问题描述】：

我正在尝试开发一个在 Intellij Idea 14.0.1 中实现 Gradle 的程序

Google 上的所有建议都说首先声明对 natives 文件夹的依赖，然后使用 -Djava.library.path="pathtonatives" 运行它

我正在做这一切，但是当您尝试启动应用程序时它仍然失败并出现 UnsatisfiedLinkError。

该文件夹是使用下面的闭包从 gradle 准备的

    task copyNativesWindows(type: Copy) {
    from configurations.compile.files {
        it instanceof ExternalModuleDependency && it.artifacts.every { it.classifier == 'natives-windows' }
    }
    into "$buildDir/natives/windows"
}

文件夹中的文件是

jinput-2.0.5.jar
jinput-platform-2.0.5-natives-windows.jar
jutils-1.0.0.jar
lwjgl-2.8.2.jar
lwjgl-platform-2.8.2-natives-windows.jar

那么为什么它只是不起作用？

【解决方案1】：

OK 看起来 -Djava.library.path 的工作方式有点问题。

如果你从 Maven 中提取，你会得到一个 lwjgl-platform-2.8.2-natives-windows.jar 这个文件包含 DLL 所以你必须将 dll 提取到一个文件夹中并将库路径指向该文件夹。
