注：
1，工具idea，版本2020
2，maven仓库：https://mvnrepository.com/
错误信息：
Could not transfer artifact org.apache.httpcomponents:httpcomponents-parent:pom:10 from/to central (https://repo.maven.apache.org/maven2):
GET request of: org/apache/httpcomponents/httpcomponents-parent/10/httpcomponents-parent-10.pom from central failed
上面说的大概意思是从中央仓库org/apache/httpcomponents/httpcomponents-parent/10/httpcomponents-parent-10.pom这个文件下载失败了。
解决：根据提供的链接地址--https://repo.maven.apache.org/maven2
按照目录一级一级向下（org/apache/httpcomponents/httpcomponents-parent/10/），找到httpcomponents-parent-10.pom并下载下来，
放在本地仓库/.m2/repository/org/apache/httpcomponents/httpcomponents-parent/10/。
