5) mvn archetype:generate

获取帮助

mvn -h

命令格式

usage: mvn [options] [<goal(s)>] [<phase(s)>]

-D,--define <arg>

Define a system property

Defines a system property. This will take priority over any other property specified.

eg. 

mvn archetype:generate -D archetypeCatalog=file://E:/e/maven

mvn archetype:generate -DarchetypeCatalog=file://E:/e/maven

mvn archetype:generate --define archetypeCatalog=file://E:/e/maven

其中第二种方式较为常用

================================================================================

mvn archetype:generate

(1) 使用步骤

点击查看具体参数及用法

mvn -l E:emavenlog.txt archetype:generate

步骤：

1.默认为setting.xml 中的interactiveMode 交互模式

2.列出原型

3.选择原型，默认为maven-archetype-quickstart （或者过滤原型后，从结果集中重新选择原型）

4.选择version

5.定义groupId

6.定义artifactId

7.定义version

8.定义package

9.确认

备注：输入值可以覆盖默认值，不输入则以默认值为准。

(2) Optional Parameters

archetypeCatalog

The archetype catalogs to use to build a list and let the user choose from. It is a comma separated list of catalogs. Catalogs use the following schemes:

• 'file://...' with archetype-catalog.xml automatically appended when pointing to a directory
• 'http://...' or 'https://...' with archetype-catalog.xml always appended
• 'local' which is the shortcut for 'file://~/.m2/archetype-catalog.xml'
• 'remote' which is the shortcut for Maven Central repository, ie 'http://repo.maven.apache.org/maven2'
• 'internal' which is an internal catalog

Since 2.0-alpha-5, default value is no longer internal,local but remote,local. If Maven Central repository catalog file is empty, internal catalog is used instead.
Default value is: remote,local.
User property is: archetypeCatalog.

说明：

该参数指定多个时以","英文逗号分割。

如果指定的是目录则自动拼接archetype-catalog.xml 

不设置改参数时默认使用remote,local

当使用remote时会从maven中央仓库获取xml文件，即：http://repo.maven.apache.org/maven2/archetype-catalog.xml

中央仓库获取文件会很慢，可以用迅雷等工具下载到本地，以'file://...'形式使用

(3) archetype-catalog.xml

<?xml version="1.0" encoding="UTF-8"?>
<archetype-catalog>
  <archetypes>
     <archetype>
      <groupId>org.apache.maven.archetypes</groupId>
      <artifactId>maven-archetype-quickstart</artifactId>
      <version>1.1</version>
      <description>An archetype which contains a sample Maven project.</description>
    </archetype>
  </archetypes>
</archetype-catalog>
