   <description>This static analysis POM serves as parent POM for all my Jenkins Plugins. It basically enhances the
-    Parent POM for Jenkins Plugins (see https://github.com/jenkinsci/plugin-pom)
-    with a predefined configuration of several static analysis tools. Additionally, it provides a fix set of test dependencies that are common
-    to all my plugins. This POM enforces the Java style guide (see https://github.com/uhafner/codingstyle) that I am using
-    in these plugins (and in my lectures at the Munich University of Applied Sciences).
