Java踩坑1.Plugin org.apache.maven.plugins:maven-install-plugin:2.5 could not

首次运行 maven install 或任何一个插件时，报错：

Downloading from huaweicloud: https://repo.huaweicloud.com/repository/maven/org/apache/maven/plugins/maven-install-plugin/2.5/maven-clean-plugin-2.5.pom

在IDE中报错信息很长不方便看，我只看了第一句，就是本文标题那句，看不出原因。静下心看到最后一句，才发现和https有关。

解决方法一是在file - settings - maven - runner 右边VM options : 添加

-Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true

如此，不管是http协议的下载地址，还是国内一些https地址，都可以不报错。

解决方法二，同Java踩坑2，显然这个方法更安全一些。
