This is the first problem you are going to need to address and is most
likely caused by a bad project configuration:

Caused by: java.lang.ClassFormatError: Duplicate method name&signature in
class file sim/util/media/chart/XYChartGenerator

Since I don't have the project in front of me the best advice I can offer
is to avoid using the MASON .java files directly and just reference the JAR
instead.

Little red X next to components can have a lot of meanings - would need to
see the details since that could be anything from a syntax error to
referencing a class that Eclipse can't find.
