我刚刚开始使用 Maven，目前正在关注来自 http://www.sonatype.com/books/mvnex-book/reference/simple-project-sect-create-simple.html 的文章:
To start a new Maven project, use the Maven Archetype plugin from the command line. Run the archetype:generate goal, select archetype #77, and then enter "Y" to confirm and generate the new project:
我的环境是:
albert@albertkam:~/java/mvn-test> mvn -v
Apache Maven 3.0.1 (r1038046; 2010-11-23 17:58:32+0700)
Java version: 1.6.0_22
Java home: /home/albert/java/jdk1.6.0_22/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux" version: "2.6.34-12-desktop" arch: "i386" Family: "unix"
这就是我所做的 mvn archetype:generate(在我的情况下，快速启动原型(prototype)似乎是 98？)
....
98: remote -> maven-archetype-quickstart (An archetype which contains a sample Maven project.)
....
360: remote -> wikbook.archetype (-)
361: remote -> circumflex-archetype (-)
362: remote -> javg-minimal-archetype (-)
Choose a number: 98: 98
Choose version:
1: 1.0-alpha-1
2: 1.0-alpha-2
3: 1.0-alpha-3
4: 1.0-alpha-4
5: 1.0
6: 1.1
Choose a number: 6: 1

这个错误的原因是什么？我错过了什么吗？
很抱歉在这里问这个问题，但无论如何我可以包装“代码示例”部分吗？我为输出消息选择了“代码示例”部分以保留新行，“blockquote”不会那样做。
最佳答案
尝试使用最新版本的原型(prototype) 1.1，这是提供给您的默认选项 (6)。
Choose a number: 6: 6
如果您只是按 enter 键而不输入选项，当出现默认值时，默认值将被选中并且不会被覆盖。
关于maven - 第一次 mvn 原型(prototype) :generate failed，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/4656316/
