Ошибка архетипа Maven при создании нового проекта Apache Apex

Question

Я следую документации, связанной с Apache Apex, которая помогает создать проект запуска. https://apex.apache.org/docs/apex-3.4/apex_development_setup/#creating-new-apex-project

При выполнении команды Maven,

@echo off 
@rem Script for creating a new application 
setlocal 
mvn archetype:generate -DarchetypeGroupId=org.apache.apex -DarchetypeArtifactId=apex-app-archetype -DarchetypeVersion=3.5.0 -DgroupId=com.example -Dpackage=com.example.myapexapp -DartifactId=myapexapp -Dversion=1.0-SNAPSHOT 
endlocal 

я столкнулся следующий вопрос.

В чем причина этой ошибки?

Вероятно, существует проблема с подключением к Интернету в репозитории maven. Попробуйте загрузить необходимые артефакты вручную:

mvn dependency:get -DremoteRepositories=http://repo1.maven.org/maven2/ -DgroupId=org.apache.apex -DartifactId=apex-app-archetype -Dversion=3.5.0
