找不到Maven插件-IntelliJ IDEA 2019.2（社区版）

Question

我是IntelliJ IDEA的新手，我只安装了1个maven项目；当我使用mvn compile从终端进行编译时，我得到 BUILD SUCCESS ：

[INFO]
[INFO] --- maven-resources-plugin:2.6:resources (default-resources) @ cartas ---
[INFO] Using 'UTF-8' encoding to copy filtered resources.
[INFO] Copying 11 resources

但是在IDE中，许多插件出现了一些错误：

我正在使用：

IntelliJ IDEA 2019.2 (Community Edition)
Build #IC-192.5728.98, built on July 23, 2019
Runtime version: 11.0.3+12-b304.10 amd64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Windows 10 10.0

并使用在IntelliJ的maven设置中选中的插件注册表。

Answer 1

IDEA 2019.2中的已知错误，应在2019.2.1或/和2019.3中修复

Answer 2

从 C:\Users\%USERNAME%\.m2\repository\org\apache 中删除 maven 文件夹。删除目录后，请重新启动IDE并等待软件包下载
