我正在尝试使用Maven和eclipse创建一个基于JPA的项目。我尝试在eclipse项目创建中使用创建新maven项目的jpa-maven-archetype，但它回击了这个错误
Could not resolve archetype com.rfc.maven.archetypes:jpa-maven-archetype:RELEASE from any of the configured repositories.
Could not resolve artifact com.rfc.maven.archetypes:jpa-maven-archetype:pom:RELEASE
Failed to resolve version for com.rfc.maven.archetypes:jpa-maven-archetype:pom:RELEASE: Could not find metadata com.rfc.maven.archetypes:jpa-maven-archetype/maven-metadata.xml in local (/home/sebastian/.m2/repository)
Failed to resolve version for com.rfc.maven.archetypes:jpa-maven-archetype:pom:RELEASE: Could not find metadata com.rfc.maven.archetypes:jpa-maven-archetype/maven-metadata.xml in local (/home/sebastian/.m2/repository)
基本上，eclipse插件正在查看我的本地存储库而不是远程存储库。所以我尝试使用命令行并使用以下命令显式指定远程存储库
mvn org.apache.maven.plugins:maven-archetype-plugin:1.0-alpha-7:create \
-DgroupId=com.something -DartifactId=jpaexample \
-DarchetypeArtifactId=jpa-maven-archetype \
-DarchetypeVersion=RELEASE \
-DremoteRepositories=http://maven.rodcoffin.com/repo \
-DinteractiveMode=false
我收到了这个错误

似乎repo maven.rodcoffin.com/repo无效，或者我的maven设置有问题。我不确定哪一个，如果有人可以给我指点在哪里搜索，那将会有所帮助。
此外，如果repo maven.rodcoffin.com/repo无效。我有什么其他选择来创建JPA原型项目。我是否必须制作一个简单的maven项目，然后将其转换为JPA，如here所示。
编辑：我只是通过创建一个maven快速类型的achetype，然后使用persistence.xml为我的项目来解决问题。 所以请忽略这个问题。
