[英]Deeplearning4j class not found
首先感谢您抽出宝贵的时间来帮助我。 我叫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具有深度学习功能的spigot插件（用于MC）。 我正在尝试使用deeplearning4j。 我知道我可以在spigotmc网站上提出这个问题，但是我认为它们不会有太大帮助，因为从spigotmc的先前帖子中可以看出，他们似乎并不了解很多关于dl4j的知识。 所以到目前为止，我所做的就是使用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，并为deeplearning4j添加依赖项，这是我的POM.xml：

但是，问题是，一旦我将其导出（通过向右，maven，生命周期，程序包导出），然后在plugins文件夹中尝试了jar，就会收到此错误：

我试图通过Google搜索此错误，但没有找到有用的信息，我已经在该网站上搜索了答案，并且大多数人都将我带回了我首先遵循的快速入门指南。 帮助将不胜感激。

创建一个uberjar并将其用于您的插件。 使用Maven Shade插件执行此操作： https : //github.com/deeplearning4j/dl4j-examples/blob/master/standalone-sample-project/pom.xml#L91
