Listing Active Profiles

Maven profiles can be defined in either pom.xml, profiles.xml, ~/.m2/settings.xml, or ${M2_HOME}/conf/settings.xml. With these four levels, there's no good way of keeping track of profiles available to a particular project without remembering which profiles are defined in these four files. To make it easier to keep track of which profiles are available, and where they have been defined, the Maven Help plugin defines a goal, active-profiles, which lists all the active profiles and where they have been defined. You can run the active-profiles goal, as follows:

$ mvn help:active-profiles
Active Profiles for Project 'My Project':

The following profiles are active:

 - my-settings-profile (source: settings.xml)
 - my-external-profile (source: profiles.xml)
 - my-internal-profile (source: pom.xml)
