Maven custom skeleton process that has been used in the detailed

The MAVEN skeleton is implemented by the skeleton plug-in, and the entire skeleton flow is expressed in the entire flowchart in the following chart, the source of Maven's website.


maven Skeleton Introduction:

When you create a project using Mave, it is natural to use the skeleton of Maven's self, for example:

Maven Archetypes

Maven provides several achetype artifacts:

archetype Artifactids	Description
Maven-archetype-archetype	An archetype to generate a sample archetype.
Maven-archetype-j2ee-simple	An archetype to generate a simplifed sample Java application.
Maven-archetype-mojo (deprecated)	Deprecated in favour of Maven-archetype-plugin, which has a better name.
Maven-archetype-plugin	An archetype to generate a sample Maven plugin.
Maven-archetype-plugin-site	An archetype to generate a sample Maven plugin site.
Maven-archetype-portlet	An archetype to generate a sample JSR-268 Portlet.
Maven-archetype-quickstart	An archetype to generate a sample Maven project.
Maven-archetype-simple	An archetype to generate a simple Maven project.
Maven-archetype-site	An archetype to generate a sample Maven site which demonstrates some of the supported document types like APT, Xdoc, and F ML and demonstrates to i18n your site.
Maven-archetype-site-simple	An archetype to generate a sample Maven site.
Maven-archetype-webapp	An archetype to generate a sample Maven Webapp project.

Common such as: Maven-archetype-webapp,maven-archetype-simple.

The MAVEN skeleton plug-in all commands are as follows:

Plugin Documentation Goals available for this plugin:

Goal	Description
Archetype:crawl	Crawl a Maven Repository (filesystem, not HTTP) and creates Acatalog file.
Archetype:create	deprecated. Please use the Generate Mojo instead.
Archetype:create-from-project	Creates a archetype project from the current project. This goal reads your source and resource files, the values ofits parameters, and properties for you specify in A.property file , and uses them to create a Mavenarchetype project using the Maven-archetype packaging. If you buildthe resulting project, it would create the archetype. Can thenuse this archetype to create new projects that resemble theoriginal. The maven-archetype-plugin uses velocity to expand Templatefiles, and this documentation talks about ' Velocity Properties ' , which are values substituted into Velocity templates. Seethevelocity User ' s Guide for more information. This goal modifies the "the" Current Projectto form the Velocity template files, make up the Archet Ype. GAV the GAV values for the current project are replaced Byproperties:groupid, Artifactid, and version. The user chooses NewValues for this is generating a project from the archetype. Package all of the files under one specified Java (or cognate) package arerelocated to a project this user chooses when G Enerating Aproject. References to the class name are replaced by a propertyreference. For example, if the current project ' s sources are in Thepackage org.apache.saltedpeanuts, then any example ofthe string or G.apache.saltedpeanuts is replaced withthe Velocity property Reference ${packagename}. Whenthe user generates a project, this is in turn replaced by his orher choice of a package. Custom properties you could identify additional strings that should to be replaced byparameters. To add custom properties, your must use the Propertyfile parameter to specify a PropeRty file. seethe documentation for Propertyfile for Thedetails. Note ' may need to edit ' results of this goal. Thisgoal has no way to exclude unwanted files, or add copyright Noticesto the Velocity templates, or add more complex elem Ents to Thearchetype metadata file. This is goal also generates a simple integration-test thatexercises the generated archetype.
Archetype:generate	Generates a new project from a archetype, or updates the actualproject if using a partial archetype. If The project is fullygenerated, it's generated in a directory corresponding to Itsartifactid. If the project is updated with a partial archetype, itis do in the current directory.
Archetype:help	Display Help information on Maven-archetype-plugin. Call MVN archetype:help-ddetail=true-dgoal=<goal-name> to display parameter details.
Archetype:integration-test	Execute the Archetype integration tests, consisting ingenerating projects from the current archetype and Optionallycompari Ng generated projects with reference copy. Each IT consists of a sub-directory insrc/test/resources/projects containing:a goal.txt file, containing a list of goals To runagainst the generated project (can is empty, content ignored Beforemaven-archetype-plugin 2.1), an Archetype.propert IES file, containingproperties for project Generation, a optional reference/directory containing copy of the Expected project created from the IT. Notice that it's expected to being run as part as the A build afterthe package phase and don't directly as a goal from CLI.
Archetype:jar	Build a JAR from the current archetype project.
Archetype:update-local-catalog	Updates the Local Catalog

The first thing you do before you create your own skeleton is a command:

Archetype:generate

This command is useful for creating a MAVEN project from skeleton information.

It will allow you to select the Maven skeleton you need and then enter Groupid,packagename,package,artifactid,version. Then you create the MAVEN project in your directory.

create our own MAVEN skeleton based on our custom project, which is the second important command:

Archetype:create-from-projeCT

To customize the directory structure for your project:

Contents of the Pom file for this project:

<project xmlns= "http://maven.apache.org/POM/4.0.0" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"

Go to the root of this project and execute the command:

The following files are found in the target directory of the project:

---target
---generated-sources
---archetype
---our project
Access to the Archetype directory, which is the root of our project to execute:

Now our Maven skeleton has been built.

Execute the Mvn:archetype:crawl command, the third important command:

We will find the archetype-catalog.xml skeleton configuration file generated at the root of our local warehouse. View the contents of this file as follows:

<archetype>
      <groupId>com.lgy.archetype-demo</groupId>
      <artifactId> archetype-demo-archetype</artifactid>
      <version>1.0.0-RELEASE</version>
      < Description>archetype-demo</description>
    </archetype>

By referencing the skeleton file and selecting the skeleton in Eclipse, you can find that the project is created with our skeleton project template.

* When using the archetype:generate command to create the MAVEN skeleton project, we found that sometimes there are too many skeletons, we can use the filter over LV, reference maven this command parameter:

For example:

mvn archetype:generate-darchetypecatelog=local Local

MVN archetype:generate-darchetypecatelog=romote Remote

MVN archetype:generate-darchetypecatelog=http:localhost:8080/archetype-catalog.xml Remote
