project

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

Element	Description
`modelVersion`	Declares to which version of project descriptor this POM conforms.
`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`	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`	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`	The current version of the artifact produced by this project.
`packaging`	The type of artifact this project produces, for example `jarwarearpom`. Plugins can create their own packaging, and therefore their own packaging types, so this list does not contain all possible types. The default value is `jar`.
`name`	The full name of the project.
`description`	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`	The URL to the project's homepage.
`inceptionYear`	The year of the project's inception, specified with 4 digits. This value is used when generating copyright notices as well as being informational.

`dependencies`	Additional dependencies that this project needs to introduce to the plugin's classloader.
`goals`	Deprecated. Unused by Maven.

A type can be mapped to a different extension and a classifier. The type often correspongs to the packaging used, though this is also not always the case. Some examples are `jar`, `war`, `ejb-client` and `test-jar`. New types can be defined by plugins that set `extensions` to `true`, so this is not a complete list. The default value is `jar`.

It also assists in determining which artifacts to include in a distribution of this project. For more information, see the dependency mechanism.
`systemPath`	FOR SYSTEM SCOPE ONLY. Note that use of this property is discouraged and may be replaced in later versions. This specifies the path on the filesystem for this dependency. Requires an absolute path for the value, not relative. Use a property that gives the machine specific absolute path, e.g. `${java.home}`.
`exclusions`	Lists a set of artifacts that should be excluded from this dependency's artifact list when it comes to calculating transitive dependencies.
`optional`	Indicates the dependency is optional for use of this library. While the version of the dependency will be taken into account for dependency calculation if the library is used elsewhere, it will not be passed on transitively. The default value is `false`.
