【问题描述】：
首先感谢您花时间帮助我。我的名字是 Matt，我一直在尝试学习 java，以及创建 mc 插件。我一直在尝试制作一个包含深度学习的插口插件（用于 MC）。我正在尝试使用 deeplearning4j。我知道我可以将这个问题放在 spigotmc 网站上，但我认为它们不会很有帮助，因为从查看 spigotmc 以前的帖子来看，看起来他们中的许多人对 dl4j 了解不多。所以到目前为止我所做的是使用 dl4j 网站上的快速入门指南来设置 maven 和 Intellij，并在 intellij 中创建一个 maven 项目并添加 deeplearning4j 的依赖项，这是我的 POM.xml：

但是，问题是，一旦我导出它（通过向右、maven、生命周期、包）并尝试插件文件夹中的 jar，我会收到此错误：

我试图用谷歌搜索这个错误，但没有发现任何有用的信息，我已经在这个网站上搜索了答案，其中大多数让我回到我最初遵循的快速入门指南。非常感谢您的帮助。
