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

Question

我是 Maven 的新手，我正在向我的pom.xml文件添加一些依賴項，但是我添加的幾個依賴項一直在說：

未找到依賴項“org.springframework.boot:spring-boot-starter-log4j2:2.3.5.RELEASE”

這是否意味着這個包不再存在？ 或者，它沒有在我的項目中找到？ 我需要在我的源路徑中添加一些 jar 文件嗎？ 任何幫助/評論表示贊賞。

Answer 1

該錯誤似乎已通過簡單地刷新 Maven Changes 解決。 完成依賴項的編輯后，此圖標將顯示為“加載 Maven 更改”，這將安裝您的包。

下面是我的 pom 文件以供參考：
