#jwalk jwalk is a simple tool for looking in directories and archives for class files, typically you'd use it to look in a directory full of jars to find which jar has a named class. It looks inside jar, war and zip archives recursively so it can find a class within a jar inside a war inside a zip for instance.

##Building

gradle jar

##Running

java -jar jwalk.jar {path you want to search} {text to search for in the class name}

If you don't specify search text all classes are returned and so can be piped to grep or something for more sophisticated matching.

##Example This is an example of running jwalk straight after gradle jar on the build directory (where gradle builds things to) see how it finds the classes in both the classes sub-directory and the jar.

###Command

java -jar build/libs/jwalk.jar build Proc

###Output

/Users/tom/dev/jwalk/build/classes/main/thaggie/jwalk/Main$ThreadLocalZipFileProcessor.class
/Users/tom/dev/jwalk/build/classes/main/thaggie/jwalk/ZipFileProcessor.class
/Users/tom/dev/jwalk/build/libs/jwalk.jar:thaggie/jwalk/Main$ThreadLocalZipFileProcessor.class
/Users/tom/dev/jwalk/build/libs/jwalk.jar:thaggie/jwalk/ZipFileProcessor.class

##Run Script Typically you'd want a script that runs the jar to make it less awkward to call:

#!/bin/bash

scriptdir=`dirname "$BASH_SOURCE"`
java -jar $scriptdir/jwalk.jar $@

So this would be somewhere in your PATH with jwalk.jar in the same directory.

This woud mean the example above would become:

jwalk build Proc
