“未找到依赖项'org.springframework.boot:spring-boot-starter-log4j2:2.3.5.RELEASE'”

Question

我是 Maven 新手，我正在向我的 pom.xml 文件添加一些依赖项，但我添加的一些依赖项一直在说：

依赖 'org.springframework.boot:spring-boot-starter-log4j2:2.3.5.RELEASE' 没找到

这是否意味着这个包不再存在？或者，在我的项目中找不到它？我需要在我的源路径中添加一些 jar 文件吗？任何帮助/评论表示赞赏。

Answer 1

该错误似乎已通过简单地刷新 Maven Changes 得到解决。完成对依赖项的编辑后，此图标将显示为“加载 Maven 更改”，这将安装您的包。

下面是我的 pom 文件供参考：
