# @Function

# Find duplicate classes among java lib dirs and class dirs.

#

# @Usage

# $ show-duplicate-java-classes # search jars from current dir

# $ show-duplicate-java-classes path/to/lib_dir1 /path/to/lib_dir2

# $ show-duplicate-java-classes -c path/to/class_dir1 -c /path/to/class_dir2

# $ show-duplicate-java-classes -c path/to/class_dir1 path/to/lib_dir1

# $ show-duplicate-java-classes -L path/to/lib_dir1 # search jars in the subdirectories of lib dir

# $ show-duplicate-java-classes -J path/to/lib_dir1 # search jars in the jar file
