I noticed that the resulting swf file of an mxmlc compilation is missing classes that are not used but still given to the compiler via the -source-path option.
How can this be avoided?
Also, how does the compiler find out which classes are not used?
If you want the unused classes to be included, using an import on those classes should be sufficient. Make sure you include the import in a class that is being used.
Add the compiler flag "link-report filename" generates a report to see what classes are included.
