In "pom.xml" of "VadereGui", "VadereSimultor", "VadereState" and "VadereUtils", use version 2.19 of Surefire plugin to be able to skip tests via CLI.

Version 2.19 or higher of Surefire plugin allows to use following notation to skip tests:

  mvn test -Dtest=!LegacyTest

Note: maybe, use "mvn test -Dtest=\!LegacyTest" (with escape character) to avoid shell interpretation of exlemation mark.
