出于某种原因，我在我的lib文件夹中发现了以下jarlog4j-1.2.14.jar.我想从我的最终战争中排除这个jar，所以我尝试了mvn依赖项：树，但我找不到父依赖项。
我还试图从Eclipse中打开依赖层次结构，但也找不到这个jar。我怎样才能排除这个罐子？

具有提供范围的另一个依赖项的依赖项不会导致提供的依赖项位于类路径上。它可能存在是因为测试或构建需要它。
因此，您应该做的是检查您的最终部署单元（您自己的jar/war）并检查jar是否在lib目录中。如果是其他东西正在管理/包括该依赖项。（您可以使用mvn依赖项：tree来找出哪一个）。
有关Maven作用域的更多信息，请查看此项。本Spring介绍了如何将特定版本的Log4j2（当您使用它时）与Spring Boot结合使用。io博客帖子。

我和我的朋友正在做一个Java maven项目，它的设置和我们从Git得到的项目是一样的。在我的设置中，Maven正确地导入了所有依赖项，但对于我的朋友，它找不到任何依赖项。 我们尝试过的事情： 右键单击project，单击maven并单击Reimport。 我们都可以上网，所以这也不是问题。而且，Maven在IntelliJ中设置为自动导入。
