关于idea创建项目的一些异常

This error occurs when you employ a plugin that Maven could not download. Possible causes for this error are:

# 你正在检查一个不存在的插件，例如：错误的插件Id或者版本

You are referring to a non-existing plugin, e.g. by means of a typo in its group id, artifact id or version
#你正在使用第三方的maven插件，确实是啊，我构建新项目的时候用的是我之前的maven仓库里面有maven-plugin插件
You are using a third-party Maven plugin that is not deployed to the central Maven repository and your POM/settings is missing the required<pluginRepository> to download the plugin. Note that<repository> declarations are not considered when looking for the plugin and its dependencies, only<pluginRepositories> are searched for plugins.
The plugin repository you have configured requires authentication and Maven failed to provide the correct credentials to the server. In this case, make sure your${user.home}/.m2/settings.xml contains a<server> declaration whose<id> matches the <id> of the plugin repository to use. See theMaven Settings Reference for more details.
There is a general network problem that prevents Maven from accessing any remote repository, e.g. a missing proxy configuration.
Maven failed to save the files to your local repository, see LocalRepositoryNotAccessibleException for more details.
The plugin repository you have configured is disabled for the specific version of the plugin you requested. For instance, if you want to use a SNAPSHOT version of a plugin, make sure you don't have<snapshots><enabled>false</enabled></snapshots> configured. Likewise, in order to resolve a released version of the plugin, the plugin repository should not be configured with<releases><enabled>false</enabled></releases>. See thePOM Reference for more information on repository configuration.
