archetype:create-from-project

Full name:

org.apache.maven.plugins:maven-archetype-plugin:2.2:create-from-project

Description:

Creates an archetype project from the current project.

This goal reads your source and resource files, the values of its parameters, and properties you specify in a .property file, and uses them to create a Maven archetype project using the maven-archetype packaging. If you build the resulting project, it will create the archetype. You can then use this archetype to create new projects that resemble the original.

The maven-archetype-plugin uses Velocity to expand template files, and this documentation talks about 'Velocity Properties', which are values substituted into Velocity templates. See The Velocity User's Guide for more information.

This goal modifies the text of the files of the current project to form the Velocity template files that make up the archetype.

GAV
The GAV values for the current project are replaced by properties: groupId, artifactId, and version. The user chooses new values for these when generating a project from the archetype.
package
All the files under one specified Java (or cognate) package are relocated to a project that the user chooses when generating a project. References to the class name are replaced by a property reference. For example, if the current project's sources are in the package org.apache.saltedpeanuts, then any example of the string org.apache.saltedpeanuts is replaced with the Velocity property reference ${packageName}. When the user generates a project, this is in turn replaced by his or her choice of a package.
custom properties
You may identify additional strings that should be replaced by parameters. To add custom properties, you must use the propertyFile parameter to specify a property file. See the documentation for propertyFile for the details.

Note that you may need to edit the results of this goal. This goal has no way to exclude unwanted files, or add copyright notices to the Velocity templates, or add more complex elements to the archetype metadata file.

This goal also generates a simple integration-test that exercises the generated archetype.

Attributes:

  • Requires a Maven project to be executed.
  • Executes as an aggregator plugin.
  • Invokes the execution of the lifecycle phase generate-sources prior to executing itself.

Optional Parameters

Name Type Since Description
archetypeFilteredExtentions String - File extensions which are checked for project's text files (vs binary files).
archetypeLanguages String - Directory names which are checked for project's sources main package.
archetypePostPhase String - The property telling which phase to call on the generated archetype. Interesting values are: package, integration-test, install and deploy.
Default value is: package.
archetypeRegistryFile File - The location of the registry file.
defaultEncoding String - Velocity templates encoding.
Default value is: UTF-8.
interactive boolean - Enable the interactive mode to define the archetype from the project.
Default value is: false.
keepParent boolean - POMs in archetype are created with their initial parent. This property is ignored when preserveCData is true.
outputDirectory File - The directory where the archetype should be created.
packageName String - The package name for Java source files to be incorporated in the archetype and and relocated to the package that the user selects.
partialArchetype boolean - Create a partial archetype.
preserveCData boolean - Create pom's velocity templates with CDATA preservation. This uses the String.replaceAll() method and risks to have some overly replacement capabilities (beware of '1.0' value).
propertyFile File - The property file that holds the plugin configuration. If this is provided, then the plugin reads properties from here. The properties in here can be standard properties listed below or custom properties for this archetype. The standard properties are below. Several of them overlap parameters of this goal; it's better to just set the parameter.
package
See the packageName parameter.
archetype.languages
See the archetypeLanguages parameter.
groupId
The default groupId of the generated project.
artifactId
The default artifactId of the generated project.
version
The default version of the generated project.
archetype.filteredExtensions
See the filteredExensions parameter.
Custom Properties

Custom properties allow you to replace some constant values in the project's files with Velocity macro references. When a user generates a project from your archetype he or she gets the opportunity to replace the value from the source project.

Custom property names may not contain the '.' character.

For example, if you include a line like the following in your property file:

        cxf-version=2.5.1-SNAPSHOT
the plugin will search your files for the string 
2.5.1-SNAPSHOT
and replace them with references to a velocity macro 
cxf-version
. It will then list 
cxf-version
as a 
requiredProperty
in the archetype-metadata.xml, with 
2.5.1-SNAPSHOT
as the default value.
