Maven

This is a reference for the Maven project descriptor used in Maven.

An XSD is available at:

• http://maven.apache.org/xsd/maven-v3_0_0.xsd for Maven 1.1.
• http://maven.apache.org/xsd/maven-4.0.0.xsd for Maven 2.0.

project

The  element is the root of the descriptor. The following table lists all of the possible child elements.

Element	Type	Description
modelVersion	String	Declares to which version of project descriptor this POM conforms.
parent	Parent	The location of the parent project, if one exists. Values from the parent project will be the default for this project if they are left unspecified. The location is given as a group ID, artifact ID and version.
groupId	String	A universally unique identifier for a project. It is normal to use a fully-qualified package name to distinguish it from other projects with a similar name (eg.org.apache.maven).
artifactId	String	The identifier for this artifact that is unique within the group given by the group ID. An artifact is something that is either produced or used by a project. Examples of artifacts produced by Maven for a project include: JARs, source and binary distributions, and WARs.
version	String	The current version of the artifact produced by this project.
packaging	String	The type of artifact this project produces, for example jar war ear pom. Plugins can create their own packaging, and therefore their own packaging types, so this list does not contain all possible types.  Default value is: jar.
name	String	The full name of the project.
description	String	A detailed description of the project, used by Maven whenever it needs to describe the project, such as on the web site. While this element can be specified as CDATA to enable the use of HTML tags within the description, it is discouraged to allow plain text representation. If you need to modify the index page of the generated web site, you are able to specify your own instead of adjusting this text.
url	String	The URL to the project's homepage.  Default value is: parent value [+ path adjustment] + artifactId
inceptionYear	String	The year of the project's inception, specified with 4 digits. This value is used when generating copyright notices as well as being informational.
organization	Organization	This element describes various attributes of the organization to which the project belongs. These attributes are utilized when documentation is created (for copyright notices and links).
licenses/license*	List	(Many) This element describes all of the licenses for this project. Each license is described by a license element, which is then described by additional elements. Projects should only list the license(s) that applies to the project and not the licenses that apply to dependencies. If multiple licenses are listed, it is assumed that the user can select any of them, not that they must accept all.
developers/developer*	List	(Many) Describes the committers of a project.
contributors/contributor*	List	(Many) Describes the contributors to a project that are not yet committers.
mailingLists/mailingList*	List	(Many) Contains information about a project's mailing lists.
prerequisites	Prerequisites	Describes the prerequisites in the build environment for this project.
modules/module*	List	(Many) The modules (sometimes called subprojects) to build as a part of this project. Each module listed is a relative path to the directory containing the module. To be consistent with the way default urls are calculated from parent, it is recommended to have module names match artifact ids.
scm	Scm	Specification for the SCM used by the project, such as CVS, Subversion, etc.
issueManagement	IssueManagement	The project's issue management system information.
ciManagement	CiManagement	The project's continuous integration information.
distributionManagement	DistributionManagement	Distribution information for a project that enables deployment of the site and artifacts to remote web servers and repositories respectively.
properties/key=value*	Properties	(Many) Properties that can be used throughout the POM as a substitution, and are used as filters in resources if enabled. The format is value.
dependencyManagement	DependencyManagement	Default dependency information for projects that inherit from this one. The dependencies in this section are not immediately resolved. Instead, when a POM derived from this one declares a dependency described by a matching groupId and artifactId, the version and other values from this section are used for that dependency if they were not already specified.
dependencies/dependency*	List	(Many) This element describes all of the dependencies associated with a project. These dependencies are used to construct a classpath for your project during the build process. They are automatically downloaded from the repositories defined in this project. See the dependency mechanism for more information.
repositories/repository*	List	(Many) The lists of the remote repositories for discovering dependencies and extensions.
pluginRepositories/pluginRepository*	List	(Many) The lists of the remote repositories for discovering plugins for builds and reports.
build	Build	Information required to build the project.
reports	DOM	Deprecated. Now ignored by Maven.
reporting	Reporting	This element includes the specification of report plugins to use to generate the reports on the Maven-generated site. These reports will be run when a user executes mvn site. All of the reports will be included in the navigation bar for browsing.
profiles/profile*	List	(Many) A listing of project-local build profiles which will modify the build process when activated.

parent

The  element contains information required to locate the parent project from which this project will inherit from. Note: The children of this element are not interpolated and must be given as literal values.

Element	Type	Description
groupId	String	The group id of the parent project to inherit from.
artifactId	String	The artifact id of the parent project to inherit from.
version	String	The version of the parent project to inherit.
relativePath	String	The relative path of the parent pom.xml file within the check out. If not specified, it defaults to ../pom.xml. Maven looks for the parent POM first in this location on the filesystem, then the local repository, and lastly in the remote repo. relativePathallows you to select a different location, for example when your structure is flat, or deeper without an intermediate parent POM. However, the group ID, artifact ID and version are still required, and must match the file in the location given or it will revert to the repository for the POM. This feature is only for enhancing the development in a local checkout of that project. Set the value to an empty string in case you want to disable the feature and always resolve the parent POM from the repositories.  Default value is: ../pom.xml.

organization

Specifies the organization that produces this project.

Element	Type	Description
name	String	The full name of the organization.
url	String	The URL to the organization's home page.

license

Describes the licenses for this project. This is used to generate the license page of the project's web site, as well as being taken into consideration in other reporting and validation. The licenses listed for the project are that of the project itself, and not of dependencies.

Element	Type	Description
name	String	The full legal name of the license.
url	String	The official url for the license text.
