我正在关注教程： http: //persistentdesigns.com/wp/jersey-spring-and-jpa/ 这里说，运行命令
mvn archetype:generate -DarchetypeCatalog=http://download.java.net/maven/2
之后给出 groupId、ArtifactId 等。我运行了上面的命令。但在询问 groupId 之前，它要求：
选择一个数字或应用过滤器（格式：[groupId:]artifactId，包含区分大小写）：
因为教程中没有给出这个数字，所以我在命令行中查看了给定的选项并选择了 3。之后它询问了 groupId 和其他。我给出了所有选项，然后按回车键。但我得到一个构建失败，说读取 POM 时出错。
这是输出：

grizzly (Archetype for creating a RESTful web application with Jersey and Grizzly)

我不知道为什么它不读取 POM。我在这里错过了什么吗？请帮忙！提前致谢！
