 # Tasks
+* Es steht nur noch ein Task aus:
+## Klassen aus Default Package laden
+* Das kann für jede SourceFile anders sein
+* Momentan funktioniert der Compiler sowieso nur mit einer SourceFile!
+* an allen Stellen, an denen die Imports der SourceFile beachtet werden, müssen jetzt auch alle Klassen aus dem gleichen Ordner beachtet werden
+
+### Stand
+* CompilationEnvironment wurde erweitert und kann alle Klassen aus einem Ordner laden
+* Allerdings funktionieren manche Tests noch nicht
+* Die Bytecode-Tests funktionieren nicht, da sich kaputte Klassen im Bytecode-Jav-Ordner befinden
+
 ## Class files in richtigen Ordner legen ##
 * Wenn Pfad übergeben, dann in Pfad + packageName
 * Ohne Pfad, direkt neben die Source File legen
