Maven source and dependencies are built incorrectly at initial compile time

When the top level pom.xml is just a wrapper for two modules, the workspace does not build correctly.
When the workspace is first loaded, references from imports or from within the source are not loaded correctly. Once a file is opened, these errors go away.

Additional Informations

Reproduziere das Problem mit dem Projekt blz-ospl v2.7 in VS Code unter Verwendung seiner pom.xml auf oberster Ebene und der beiden Modul-pom.xml-Dateien mit aktiviertem Logging. Untersuche zuerst die Import- und Build-Path-Logs; als erledigt gilt es, wenn beim anfänglichen Laden die Modulquellen und Abhängigkeiten aufgelöst werden, ohne dass eine Datei geöffnet werden muss.
