MVN原型：产生构建失败

Question

我的教程如下：http://persistentdesigns.com/wp/jersey-spring-and-jpa/ 这表示，运行命令

mvn archetype:generate -DarchetypeCatalog=http://download.java.net/maven/2 

之后给出的groupId，artifactId的，等我跑上面的命令。但询问的groupId之前，它要求：

选择一个号码或应用过滤器（格式：[的groupId：]的artifactId，区分大小写包含）：

因为，这个数字是不是在教程中给出的，我通过命令行中的给定选项并选择了3.之后，它询问了groupId和其他。我给了所有的选项，然后按下输入。但是我得到一个编译失败，说错误读取POM。

下面是输出：

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

我不知道它为什么不读书的POM。我在这里错过了什么吗？请帮忙！ 在此先感谢！

Answer 1

我能够创建一个没有任何问题的模块。 请参阅附件截图。

看起来像你通过的版本号是不正确的。

感谢

Answer 2

我解决这个问题！

对于

Define value for property 'version': 1.0-SNAPSHOT: : 

我最初进入< CR>如在教程提及。现在，我将它留空，实际上使版本为1.0-SNAPSHOT。

这解决了这个问题。现在构建成功了！下面是输出：
