JarScan

JarScan is a Java-based application that can come in handy to programmers who find themselves facing errors such as "ClassDefNotFound", "NoClassDefFoundError", or exceptions such as "ClassNotFoundException". This lightweight utility can scan a directory recursively in the attempt to find a class that you need to compile your project.

The aforementioned errors and exceptions are triggered by a missing class when you try to compile your Java project. The purpose of JarScan is to provide a quick and easy manner to locate the class files you need.

To get acquainted with the application, you should run the "help" command by typing "java -jar jarscan.jar -help" in a command console window. By doing so, you will be able to see all the parameters you can pass on to the JarScan executable and their result.

You can define the directory to begin the scan with, and configure JarScan to also scan ZIP archives. JarScan can look for files, classes or packages in certain libraries. If you instruct the application to show the search progress, you will be able to monitor it as it performs the search.

In case you don't understand how to use any of the options JarScan comes with, you should know that JarScan comes with usage examples to clarify you.
