报错如下：
Downloading from alimaven: http://maven.aliyun.com/nexus/content/groups/public/org/apache/maven/plugins/maven-archetype-plugin/maven-metadata.xml [WARNING] Could not transfer metadata org.apache.maven.plugins:maven-archetype-plugin/maven-metadata.xml from/to alimaven (http://maven.aliyun.com/nexus/content/groups/public/): Failed to transfer file: http://maven.aliyun.com/nexus/content/groups/public/org/apache/maven/plugins/maven-archetype-plugin/maven-metadata.xml. Return code is: 500 , ReasonPhrase:Internal Server Error.
由上可知：
无法从阿里云远程仓库中下载 maven-metadata.xml ，故报错
解决方案：
把 apache-maven-3.5.2\conf\settings.xml 中配置的阿里云远程仓库注释掉，改用默认的远程仓库下载即可，成功建立maven项目后觉得下载依赖的jar包慢再把注释去掉就好了
