Getting too many Proguard warnings

Question

I am trying to obfuscate my java application that is packed into a SINGEL jar. The application uses SWT gui libaries among others. I have duly listed them all in the Proguard configuration file via -libraryjars, but still I get too many warnings of the same type i.e.: "Warning: library class org.eclipse.swt.accessibility.Accessible$10 extends or implements program class org.eclipse.swt.internal.ole.win32.COMObject"

What am doing wrong here??

Here is how my Proguard configuration looks like:

-injars 'D:\Tasks\Deployment\NEW - 30.06.2011\proguard4.6\lib\fevflex.jar'

Answer 1

ProGuard manual > Troubleshooting > Warning: library class ... depends on program class ...

In this case, it looks like org.eclipse.swt.internal.ole.win32.COMObject is in your input jar fevflex.jar. You should remove it, or at least include it as part of a library jar.

Answer 2

I have noticed that you include both swt.jar and swt_64bit.jar in your libraries, while only one of these should be used at a time. Perhaps this is one of the reasons, why you are getting a lot of warnings.
