While it usually represents the extension on the filename of the dependency, that is not always the case. Some examples are jar, war, and plugin. A dependency of type plugin is loaded as a Maven plugin and not added to the project build classpath. ]]> String jar type 4.0.0 jar. While it usually represents the extension on the filename of the dependency, that is not always the case. 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. ]]> String jar classifier 4.0.0 jdk14 and jdk15. ]]> String false properties 3.0.0 war.bundle property, and if found will include the dependency in WEB-INF/lib. ]]> Properties String * scope 4.0.0 compile, runtime, test, system, and provided. Used to calculate the various classpaths used for compilation, testing, and so on. It also assists in determining which artifacts to include in a distribution of this project. For more information, see the dependency mechanism.]]> String systemPath 4.0.0 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}. ]]> String exclusions 4.0.0 Lists a set of artifacts that should be excluded from this dependency's artifact list when it comes to calculating transitive dependencies. Exclusion * optional 4.0.0 Indicates the dependency is optional for use of this library.

Relocation status 4.0.0 none (default), converted (repository manager converted this from an Maven 1 POM), partner (directly synced from a partner Maven 2 repository), deployed (was deployed from a Maven 2 instance), verified (has been hand verified as correct and final). ]]> false String License 3.0.0+ name 3.0.0+ String url 3.0.0+ String distribution 3.0.0+

The default value is ../pom.xml. Maven looks for the parent pom first in the reactor of currently building projects, then in this location on the filesystem, then the local repository, and lastly in the remote repo. relativePath allows 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.
