1. 从project创建archetype
在项目根目录下，运行
mvn archetype:create-from-project
创建的archetype工程在app_folder/target/generated-sources/archetype 目录下，其中archetype-resources包含用来创建原型项目的文件，META-INF/maven/archetype-metadata.xml
是用来对文件结构进行详细描述的源文件。
2. Archetype的一些built-in参数
| Variable | Meaning |
|---|---|
| __rootArtifactId__ | 做文件夹名替换用，例如__rootArtifactId__-dal |
| ${rootArtifactId} |
Already explained above, it holds the value entered by the user as the project name (the value that maven ask as the artifactId: inthe prompt when the user runs the archetype) |
${artifactId}
|
If your project is composed by one module, this variable will have the same value as ${rootArtifactId}, but if the project containsseveral modules, this variable will be replaced by the module name inside every module folder, for example: given a module named portlet-domain inside a project namedportlet,all the files inside this module folder that are to be filtered will have the value of the variable ${artifactId} replaced by portlet-domainwhereasthe ${rootArtifactId} variable will be replaced by portlet
|
${package}
|
The user provided package for the project, also prompted by maven when the user runs the archetype |
${packageInPathFormat}
|
The same value as ${package} variable but replacing '.' with the character'/',e.g:, for the package com.foo.bar this variable is com/foo/bar
|
${groupId}
|
The user supplied groupId for the project, prompted by maven when the user runs the archetype |
${version}
|
The user supplied version for the project, prompted by maven when the user runs the archetype |
The archetype-metadata.xml stored in the archetype-resources/META-INF/maven
folder after the project is created, is where you need to tweak what you want generated and how.
