How to deactivate maven profile in child module?

I have a profile defined in parent pom.xml and activated by property. In child module I need to de-activate it. How this can be done (it's Maven 3)?

ps. As far as I know it can't be done legally (MNG-4565, MNG-5083), but what is a possible workaround?

It depends. Child poms should not deny parent pom behaviour (it's like LSP for build process). It may be a good idea to define profile in a parent pom, but activate it only in child poms where you really need it.

If you can't do it, you could activate profile in a parent pom by a property with exact value:

<profiles>
  <profile> 
    <activation>
      <property>
        <name>environment</name>
        <value>test</value>
      </property>
    </activation>
  </profile>
</profiles>

and then redefine property value in a child pom.
