Tattletale is a tool that can help you get an overview of the project you are working on or a product that you depend on.

The tool will provide you with reports that can help you

Identify dependencies between JAR files
Find missing classes from the classpath
Spot if a class/package is located in multiple JAR files
Spot if the same JAR file is located in multiple locations
With a list of what each JAR file requires and provides
Verify the SerialVersionUID of a class
Find similar JAR files that have different version numbers
Find JAR files without a version number
Find unused JAR archives
Identify sealed / signed JAR archives
Locate a class in a JAR file
Get the OSGi status of your project
Remove black listed API usage
And generate the same reports for your .WAR and .EAR archives

Tattletale will recursive scan the directory pass as the argument for Java archives and then build the reports as HTML files.

The main HTML file is: index.html
