使用手动下载的依赖项的 POM 错误

POM errors using manually downloaded dependencies

我正在开发一个小组不久前启动的网络应用程序,但我做不到 运行。

我是 STS(Spring 工具套件)Java 的新手,并且我使用 .jar 文件手动安装了所有依赖项。但是现在我的 pom.xml 显示了很多错误。我想有一种方法可以用 Maven 解决这个问题,但我不知道该怎么做。

这里是pom.xml:

如何解决这些错误?

and I installed all the dependencies manually with .jar files.

Maven 的要点之一是它会自动下载依赖项(通常是 jar 文件)。换句话说,我怀疑您真的不知道自己在这里做什么,除非您手动下载文件背后有特定原因。

Maven 下载的所有依赖项都存储在您自己的本地存储库中(通常是 ~/.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:
