<project>元素是描述符的根。下表列出了所有可能的子元素。
| Attribute | Type | Description |
|---|---|---|
child.project.url.inherit.append.path | String | 当子级继承项目的url时，是否追加路径？注意：虽然出于技术原因，该字段的类型为String，但语义类型实际上是Boolean Default value is: trueSince: Maven 3.6.1 |
| Element | Type | Description |
|---|---|---|
modelVersion | String | 指定了当前Maven模型的版本号 |
Parent | Parent | 父项目的位置（如果存在）。如果未指定父项目中的值，则它们将是此项目的默认值。该位置以group ID, artifact ID and version的形式给出。 |
groupId | String | 项目的通用唯一标识符。通常使用完全限定的包名称来将其与具有类似名称的其他项目（例如org.apache.maven）区分开来。 |
artifactId | String | 在groupId给定的组中是唯一的。artifact是由项目生产或使用的东西。Maven为项目生成的工件的示例包括：JAR、源代码和二进制发行版以及WAR。 |
version | String | 此项目生成的artifact的当前版本。 |
packaging | String | 该项目产生的工件的类型，例如jar war ear pom。插件可以创建自己的打包，因此也可以创建它们自己的打包类型，因此该列表不包含所有可能的类型。 Default value is: |
name | String | 项目名称 |
description | String | 项目的详细描述，Maven在需要描述项目时使用，例如在网站上。虽然可以将该元素指定为CDATA以允许在描述中使用HTML标记，但不建议允许纯文本表示。如果需要修改生成的网站的索引页，则可以指定自己的索引页而不是调整此文本。 |
url | String | 项目主页的URL。 默认值为：父值[+路径调整]+（artifactId或project.directory属性），或者如果项目的子级为.project.url.inherit.append.path=“false”，则仅为父值 |
inceptionYear | String | 项目开始的年份，用4位数字指定。此值在生成版权声明以及作为信息时使用。 |
Organization | Organization | 该元素描述项目所属组织的各种属性。创建文档时使用这些属性（用于版权声明和链接）。 |
licenses/license* | List<License> | (Many) 此元素描述此项目的所有许可证。每个许可都由许可元素描述，然后由其他元素描述。项目应仅列出应用于项目的许可证，而不是应用于依赖项的许可证。如果列出了多个许可证，则假设用户可以选择其中的任何一个，而不是必须全部接受。 |
developers/developer* | List<Developer> | (Many) 描述项目的提交者。 |
contributors/contributor* | List<Contributor> | (Many) 描述尚未提交的项目参与者。 |
mailingLists/mailingList* | List<MailingList> | (Many) Contains information about a project's mailing lists. |
Prerequisites | Prerequisites | Describes the prerequisites in the build environment for this project. |
modules/module* | List<String> | (Many) 要作为此项目的一部分生成的模块（有时称为子项目）。列出的每个模块都是包含该模块的目录的相对路径。为了与从父级计算默认url的方式一致，建议模块名称与artifact ids匹配。 |
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 | 支持将站点和工件分别部署到远程web服务器和存储库的项目的分发信息。 |
properties/key=value* | Properties | (Many) 可以在整个POM中用作替代的属性，并在启用时用作资源中的筛选器。格式为<name>value</name>。 |
DependencyManagement | DependencyManagement | 从该项目继承的项目的默认依赖项信息。此部分中的依赖项不会立即解析。相反，当从该POM派生的POM声明由匹配的groupId和artifactId描述的依赖项时，如果尚未指定该部分中的版本和其他值，则将其用于该依赖项。 |
dependencies/Dependency* | List<Dependency> | (Many) 该元素描述与项目关联的所有依赖项。这些依赖项用于在构建过程中为项目构建类路径。它们将从该项目中定义的存储库中自动下载。有关详细信息，请参阅依赖关系机制。 |
repositories/Repository* | List<Repository> | (Many) The lists of the remote repositories for discovering dependencies and extensions. |
pluginRepositories/pluginRepository* | List<Repository> | (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 | 该元素包括用于在Maven生成的站点上生成报告的报告插件的规范。这些报告将在用户执行mvn站点时运行。所有报告都将包含在导航栏中以供浏览。 |
profiles/profile* | List<Profile> | (Many) 激活时将修改生成过程的项目本地生成配置文件的列表。 |
