I have made two utility classes for reading EXIF data. They both have the same class name, but are in different folders. When I compile into a jar, the compiler does not complain about these classes being named the same. When i try to run the plugin through imagej, I get a warning message in the log “Deleting duplicate plugin: …” (I have omitted the class filepath). ImageJ is deleting the class that the plugin depends on and uses the other instead (which gives incorrect results). Is it possible to tell ImageJ not to delete “duplicate” class files?
