注：
1，工具idea，版本2020
2，maven倉庫：https://mvnrepository.com/
錯誤信息：
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
上面說的大概意思是從中央倉庫org/apache/httpcomponents/httpcomponents-parent/10/httpcomponents-parent-10.pom這個文件下載失敗了。
解決：根據提供的鏈接地址--https://repo.maven.apache.org/maven2
按照目錄一級一級向下（org/apache/httpcomponents/httpcomponents-parent/10/），找到httpcomponents-parent-10.pom並下載下來，
放在本地倉庫/.m2/repository/org/apache/httpcomponents/httpcomponents-parent/10/。
