Overview

settings.xml is the place to store configuration that should not be bundled with a specific project, but it concerns the build system as a whole. This includes various "personal" configuration values, the location of the local repository, alternate remote repository servers and authentication information. Usually, this information is bundled in specific profiles.

There are two types of settings.xml files:

• global, placed in ${MAVEN_HOME}/conf/settings.xml.
• user settings, placed in ${HOME}/.m2/settings.xml. An alternate user settings file location can be specified with -s|--settings.

If both exist, the contents are merged and the user-specific values take precedence.

System properties and environment variables can be both used in settings.xml.

Note that properties defined in profiles within settings.xml cannot be dereferenced.
