Can a parent property be made final so that it cannot be overridden by a child

Is it possible to make properties in parent pom not overridable by the module pom?

For example:

if module pom says:

<properties>
    <someProperty>some value to be replaced</properties>
</properties>

and parent pom already has it declared as:

<properties>
    <someProperty>strongValue</someProperty>
</properties>

effective module pom should be:

<properties>
    <someProperty>strongValue</someProperty>
</properties>

but it is currently expected to be this:

<properties>
    <someProperty>some value to be replaced</properties>
</properties>

If yes then how to achieve it?

Solution

  • No, you can't. The idea is that if it shouldn't be possible to override a value, don't use a property. If you have no other option, you might want to force it with http://maven.apache.org/enforcer/enforcer-rules/requireProperty.html which will break the build if a property has a different value than expected.
