No, i created a pom for demo.

For explanation. It is possible to use the value of an environment variable or a property in a pom just as follows. It doesn't matter if VAR is an environment variable or a property.
{quote}{{<variable>${VAR}</variable>}}
{quote}
But it's not possible to enforce this behaviour. That ${VAR} is set.

 

To test this with the demo pom, just define environment like:
{quote}export VAR=environment
{quote}
Or pass the property like:
{quote}{{mvn install -DVAR=property}}
{quote}
It is not possible to handle both cases with the enforcer.

You can define an environment variable and/or pass a property to that and the value will be used for the property "variable".  
{quote}{{<variable>${VAR}</variable>}}
{quote}
But it's not possible to enforce this behaviour. That ${VAR} is set.

 

 

To test just define envioronment like:
{quote}export VAR=environment
{quote}
 

Or pass the property like:
{quote}{{mvn install -DVAR=property}}
{quote}

> As far a i know maven doesn't care where a value for ${variable} comes from. In a pom you can access a env.variable or a property by ${variable}.
> Also in some system the value is provided by an environment variable like CICD or by a property maybe a dev environment.
> I would suggest a new standard rule "requireVariable"  which just look like maven for a value for this variable by property or environment.
