I have been in the process of creating a "lite" version of an existing Flex application, and thereby porting many of the classes that are used by both into a library project. As such, I want to easily find all of the "orphan" classes in the original project - those classes that are no longer referenced/used by the project. Is there an Eclipse plug-in, or some other easy way to find these in Flex Builder 3?
Thanks.
Here's what I do sometimes, lets say we've been refactoring, and a class becomes obsolete, I simply move the suspecting file from Flex Builder to the desktop, rebuild the project and see if it the compiler spits out any Errors.
If it doesn't complain, I know I can safely delete it.
If your class is depended on, the compiler will throw some errors in the Problems panel in Flex Builder and give you a fairly clear hint of what's missing.
This won't be fun however if you have thousands of classes, as you have to traverse them one by one.
I would suggest, always keep copies of the old ones in Subversion, just in case you had something re-usable in there, and later you want the deleted file restored.
MXML Compiler (mxmlc) compiler has "link-report" which will generate all the classes you are using in your original application. From there, with a bit of grep / awk / xsl magic, you should be able to diff with the classes you have in your library project.
