To run the Personal Data Checker in Blueprint you need to enable the Maven profile checkPersonalData while compiling.

The checker for personal data will analyze all modules with a direct or transitive dependency to Maven module coremedia-personal-data. In your Maven output you may recognize the message Checking @PersonalData once such a module is found in your Maven build. That message may be missing as long as the maven-compiler-plugin bug MCOMPILER-536 has not been fixed.

By default, the Checker Framework will trigger a failure once it detects a violation in using personal data objects. To change the behavior to print only warnings instead, add the compiler argument -Awarns. Configure the maven-compiler-plugin for the checkPersonalData profile in Maven pom.xml files accordingly. For more configuration options have a look at the documentation at checkerframework.org.
