When I add the Scala nature to a Java Project in Eclipse by right-clicking and selecting Scala => Add Scala Nature everything seems to work fine and I can now mix my .java and .scala class files for compilation. I can mix my classes across languages. However, this only seems to work for classes and not for objects. When I create a standalone object or try to refer to a class companion object with ObjectName$.MODULE$ Eclipse is unable to locate the object. Autocomplete pops up the classes from my .scala files but none of the objects. If I just type the objects in an error occurs. I can see the object .class files in the bin directory, but Eclipse just doesn’t see them.
