What is simple way to fail a build when a property is not set?

Question

As stated in the title, how can I modify - in the simplest manner possible - a pom.xml in order to make it fails if a property is not set in the command line.

For example, mvn clean package will fail, when mvn clean package -Dfoo=bar will succeed.

I'm looking for something like the <prerequisites/> tag in the pom.xml (except that <prerequisites/> only allow me to check the Maven version)...

You can use the requireProperty goal of the maven-enforcer-plugin to fail a build if a property is missing.

Note this only requires that the property is set, so it could have been set in the pom's properties section.
