我正在制作一个spigot插件，并在onDisable函数（服务器关闭时调用）中让它保存我的数据。问题是，当它由于某种原因禁用时，它找不到我用来保存数据的类（ObjectWriter）。

然而，如下面的截图所示，类是非常有和非常存在，这也可以证明的事实，我可以保存它正常，它的工作刚刚好。它是只有当插件禁用，我有这个问题。

我已经试着修复这个问题几个月了。是的，我试着运行mvn clean。是的，我试着删除依赖jar以防它损坏。自从我遇到这个问题后，我已经搜索了所以，并尝试了每一个. single. post。没有一个工作。我不认为这是一个问题与maven比它是一个问题与依赖关闭之前的插件完成，因为有时候它确实工作了，但却没有出错。这让我非常困惑，我不知道该怎么办。
下面是我的pom.xml，如果有人想查看它：

我发现由于this post，当你在关闭服务器之前替换jar文件时会发生这种情况。这可以解释我所遇到的所有行为。
