第一次mvn archetype：生成失败

标签： maven maven-3

我刚刚开始使用maven，我目前正在关注http://www.sonatype.com/books/mvnex-book/reference/simple-project-sect-create-simple.html中的文章：

  

要启动新的Maven项目，请使用命令行中的Maven Archetype插件。运行原型：生成目标，选择原型＃77，然后输入“Y”确认并生成新项目：

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，似乎快速启动原型是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 (-)

此错误的原因是什么？我错过了什么吗？

很遗憾在这里问这个问题，但无论如何我可以打包'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”不会这样做。

1 个答案:

答案 0 :(得分：7)

尝试使用最新版本的原型1.1，这是您提供的默认选项（6）。

  

选择一个数字：6：6

如果您只是在不输入选项的情况下按Enter键，则在显示默认值时，将选择默认值并且不会覆盖默认值。
