Introduction to Pom elements in Maven

Project-Root element of POM. XML files.

Modelversion-Setting the POM version is similar to setting the project version. Currently, it seems that Maven 2 only allows this value to be 4.0.0.

Groupid-Set the organization or group ID of a project, which is one of the unique identifiers of a project (the other is artifactid ). Groupid usually uses full domain name as the attribute value. For example, the groupid attribute value of all Maven plugins is org. Apache. Maven. plugins.

Artifactid-Set the unique base name of the primary artifact generated by the current project (Note: It is base name, not name, because artifact name is composed of "<artifactid>-<version>, for example, myapp-1.0.jar ).

Packaging-Set package type to be used by this artifact (e.g. jar, war, ear, etc .). This attribute value is used not only to set whether the generated artifact is jar, war, or ear, but also to set the lifecycle (jar, war) of the process when the package artifact is set, the build lifecycle of the ear is different. The default value of packaging is jar. If your project needs to package into jar, you do not need to set this attribute.

Version-Set the version of artifact generated by the project. Maven can help you with version management. If the property value contains a "snapshot" string, it indicates that the project is in the development stage, not the release stage.

Name-Set the project name, which is usually used for Maven's generated documentation.

URL-Set the web site URL of the project. This attribute value is usually used for Maven's generated documentation.

Description-Set Project Description This attribute value is usually used for Maven's generated documentation.
