mvn archetype：生成BUILD FAILURE

Question

我正在关注教程：http://persistentdesigns.com/wp/jersey-spring-and-jpa/ 在这里，它说，运行命令

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

之后给groupId，ArtifactId等我运行上面的命令。但在要求groupId之前，它要求：

选择一个数字或应用过滤器（格式：[groupId：] artifactId，区分大小写）：

因为，在教程中没有给出这个数字，我在命令行中查看了给定的选项并选择了3.之后它要求groupId和其他。我给了所有选项然后按下回车键。但我得到一个构建失败，说错误读取POM。

这是输出：

1: http://download.java.net/maven/2 -> com.sun.jersey.archetypes:jersey-quickstart-    
grizzly (Archetype for creating a RESTful web application with Jersey and Grizzly)

我不知道它为什么不读POM。我在这里错过了什么吗？请帮忙！ 提前谢谢！

Answer 1

我解决了这个问题！

有关

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

我最初进入＆lt; CR＆gt;正如教程中提到的那样。现在，我将它留空，这实际上使版本为1.0-SNAPSHOT。

这解决了这个问题。现在构建成功了！这是输出：

6: http://download.java.net/maven/2 -> com.sun.faces.regression:i_jsf_XXXX-archetype (Archetype for mojarra JSF regression tests)

Answer 2

我能够毫无问题地创建模块。 请参阅随附的屏幕截图。

您传递的版本号似乎不正确。
