Java 无法执行目标错误

我试图用Netbeans安装Ardor3D（一个3D Java引擎），但遇到了一些问题。我成功下载并安装了所有源代码，并且在IDE中显示良好，但是当我尝试运行任何示例时，出现以下错误：

我相信这个错误是因为我在一个可移植版本的Netbeans上运行Ardor。它发现Java类路径很好，但它尝试在计算机文件本身中定位快照（？）。有人知道如何让它下载并在flashdrive中找到文件吗？我可以假设它可以通过重定向IDE查找存储库的位置来修复，但是，由于我对该主题缺乏了解，我不知道如何实现这一点。谢谢你的帮助

另外，如果你需要我上传Netbeans portable进行纠错，只需说

好吧，事实证明答案实际上是我的问题（大部分是愚蠢的）。要解决这个问题，您必须使用“示例运行程序”（duh），而不是从示例本身运行示例。由于某些原因，它不工作，否则
