在 jar 文件中获取 NoClassDefFoundError-解网

问：

我刚刚添加了新的依赖项：

<dependency>
    <groupId>com.github.hamza-cskn.obliviate-invs</groupId>
    <artifactId>core</artifactId>
    <version>4.1.13</version>
</dependency>

现在我收到 NoClassDef 错误。该库的创建者说这不是他的错。

下面是完整的 pom.xml：

我也尝试过 One-Jar，但我无法让它工作。

修复此错误。我需要它从 .jar 文件运行。我正在使用 PaperSpigot API、IntellijIDEA、Maven 和一些依赖项

EDI。添加了Megabox_clans或主类：

你在遗忘的罐子里看到那个类了吗？

0赞 Timas_bro 8/9/2023

是的，它就在这里，在 mc.obliviate.inventory.Gui 中

0赞 g00se 8/9/2023

Megabox_clans插件;没有它，我们就无法进行测试。你确实需要提供一个最小的可重现示例，但如果该类可以做到这一点，那么你可以发布它

“即使是GPT也帮不上忙。”那是因为 ChatGPT 只不过是一个令人信服的废话生成器。它可以生成漂亮的文本，但很多时候它只是想出看似合理的胡说八道，而不是真正基于现实的东西（或者它可能一只脚踩在地上，另一只脚在仙境）。
