我正在开发一个小组刚开始使用的网络应用程序，但我无法让它运行。
我是 STS（Spring Tool Suite）和 Java 的新手，我用 .jar手动安装了所有依赖项文件。但是现在我的 pom.xml 显示了很多错误。我想有一种方法可以通过Maven解决这个问题，但我不知道该怎么做。
这是 pom.xml ：

如何解决这些错误？
答案 0 :(得分：2)
我用.jar文件手动安装了所有依赖项。
Maven的一个要点是它会自动下载依赖项（通常是 jar 文件）。换句话说，我怀疑你真的不知道你在这里做了什么，除非你手动下载文件背后有一个特定的原因。
Maven下载的所有依赖项都存储在您自己的本地存储库中（通常为〜/ .m2 ）。
我刚刚测试了你的 pom 文件，它没有错误，所有依赖项都已正确下载。要解决您的错误，您只需删除本地存储库中的文件夹，然后重新构建项目，让Maven下载依赖项。

我试过你的pom，没问题：
