然后，这是我使用的正确原型吗?

Then, is it the right archetype that I'm using?

推荐答案

Eclipse Link在Maven中央存储库中不可用，您需要手动添加其存储库.例如，要使用EclipseLink 2.0的完整"版本(您没有提到要查找的工件):

EclipseLink is not available in Maven central repository, you need to add its repository manually. For example, to use the "full" version of EclipseLink 2.0 (you didn't mention the artifact you're looking for):

<dependencies>
  <dependency>
    <groupId>org.eclipse.persistence</groupId>
    <artifactId>eclipselink</artifactId>
    <version>2.0.0</version>
    <scope>compile</scope>
       ...
  </dependency>
<dependencies>
      ...
<repositories>
  <repository>
     <id>EclipseLink Repo</id>
     <url>http://www.eclipse.org/downloads/download.php?r=1&amp;nf=1&amp;file=/rt/eclipselink/maven.repo</url>
  </repository>    
      ...
</repositories> 

这在 EclipseLink/Maven 页面中进行了记录.

This is documented in the EclipseLink/Maven page.

关于您使用的原型，没有更多关于您要创建的项目类型的详细信息就不可能回答.而且无论如何，您总是可以在事后修改POM.

Regarding the archetype you're using, it's impossible to answer without more details on the kind of project you want to create. And anyway, you can always modify the POM after the facts.
