Checkstyle

Für die Programmierfächer aus Semester 1 und 2 wurde Checkstyle eingeführt. Bei der Aufgabenerstellung muss der Haken bei "statische Codeanalyse" gesetzt werden. Späteres Hinzufügen von Checkstyle ist umständlich (Export in einen anderen Kurs, Löschen im alten Kurs, erneutes Importieren, dann Haken setzen).
