由于 Maven 插件，无法从命令提示符创建 Maven 项目
Not able to create Maven project from command prompt because of maven plugins
我有多个关于 Maven 的问题。我在这里放一期。
我试图从命令提示符创建一个 Maven 项目。我的构建失败了。我尝试了 Whosebug 和其他网站中建议的多种解决方案。以下是环境详情，
Java - 1.8
Eclipse - Oxygen
Maven - 3.5
OS - Windows
当我有 运行 mvn -version 时，我在命令提示符中得到以下结果。
D:\WS-Gradle-1563>mvn -version
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T01:09:06+05:30)
Maven home: C:\apache-maven-3.5.0\bin\..
Java version: 1.8.0_121, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk1.8.0_121\jre
Default locale: en_IN, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"
maven设置正确后，我有运行这个命令来创建一个maven项目。
D:\WS-Gradle-1563>mvn archetype:generate -DgroupId=com.maven.example -DartifactId=MavenExample -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
这里我不明白一件事是，为什么默认情况下插件版本是这样的。即使我也从 eclipse 尝试过，我在与插件相关的 pom.xml 文件中遇到错误（Compiler/Resource）。我得到的输出如下所示。

在 Eclipse 中我遇到了这种类型的错误。
在版本库中，默认是下载lover版本的插件。我不明白在哪里禁用配置并下载插件的配置版本。你能帮帮我吗？
我正在尝试下载基于Maven Plugin versions.
的插件
但是，做不到。
您是否支持某些带有代理的公司网络？
如果是这样，请尝试将代理详细信息添加到您的 settings.xml，您应该 find/create 此文件位于 .m2 目录或 MAVEN_HOME/conf/ 目录
