maven profile dependency

I have a maven module with 2 profile profile-a and profile-b

profile-a can be used independent but profile-b should be run with profile-a

mvn install -P profile-a                   // valid
mvn install -P profile-a,profile-b         // valid
mvn install -P profile-b                   // INVALID

is there anyway to make sure that user cannot install the module with only profile-b? or active the profile-a automatically if profile-b used alone?

  • is there anyway to make sure that user cannot install the module with only profile-b? or active the profile-a automatically if profile-b used alone?

    No, there is no way to trigger a profile from another one (not supported, see Brett's answer to a related question) nor to strictly forbid the use of a given profile.

    The best thing you can do is to use property activation and a common property to activate both profiles:

    <project>
  ...
  </dependencies>
  <profiles>
    <profile>
      <id>profile-a</id>
      <activation>
        <property>
          <name>propertyX</name>
        </property>
      </activation>
    </profile>
    <profile>
      <id>profile-b</id>
      <activation>
        <property>
          <name>propertyX</name>
        </property>
      </activation>
    </profile>
  </profiles>
</project>

    And passing the property when invoking mvn would trigger both of them:

    $ mvn help:active-profiles -DpropertyX

Active Profiles for Project 'com.stackoverflow:Q4099626:jar:1.0-SNAPSHOT': 

The following profiles are active:

 - profile-a (source: pom)
 - profile-b (source: pom)

    That's not ideal, but currently, that's the best you can get.
