   The error message is

   Caused by: java.lang.NullPointerException: Cannot invoke "org.gradle.api.Project.getExtensions()" because "this.project" is null

   The workaround is to have following line in gradle.properties

   org.gradle.configuration-cache=false

   I was given following hints:

   1. Gradle has native support for the module system: https://docs.gradle.org/current/userguide/java_library_plugin.html#sec:java_library_modular
   2. General information page on gradle and modules: https://github.com/jjohannes/java-module-system
   3. The "modern" way to add extra module information: https://github.com/gradlex-org/extra-java-module-info#defining-extra-module-information
