Find a class somewhere inside dozens of JAR files?

#!/bin/bash

pattern=$1
shift

for jar in $(find $* -type f -name "*.jar")
do
  match=`jar -tvf $jar | grep $pattern`
  if [ ! -z "$match" ]
  then
    echo "Found in: $jar"
    echo "$match"
  fi
done

To locate jars that match a given string:

find . -name \*.jar -exec grep -l YOUR_CLASSNAME {} \;

ClassFinder is a program that's designed to solve this problem. It allows you to search recursively through directories and jar files to find all instances of a class matching a pattern. It is written in Java, not python. It has a nice GUI which makes it easy to use. And it runs fast. This release is precompiled in a runnable jar so you don't have to build it from source.

Download it here: ClassFinder 1.0

I've always used this on Windows and its worked exceptionally well.

findstr /s /m /c:"package/classname" *.jar, where

findstr.exe comes standard with Windows and the params:

• /s = recursively
• /m = print only the filename if there is a match
• /c = literal string (in this case your package name + class names separated by '/')

Hope this helps someone.

To find a class in a folder (and subfolders) bunch of JARs: https://jarscan.com/

Usage: java -jar jarscan.jar [-help | /?]
                    [-dir directory name]
                    [-zip]
                    [-showProgress]
                    <-files | -class | -package>
                    <search string 1> [search string 2]
                    [search string n]

Help:
  -help or /?           Displays this message.

  -dir                  The directory to start searching
                        from default is "."

  -zip                  Also search Zip files

  -showProgress         Show a running count of files read in

  -files or -class      Search for a file or Java class
                        contained in some library.
                        i.e. HttpServlet

  -package              Search for a Java package
                        contained in some library.
                        i.e. javax.servlet.http

  search string         The file or package to
                        search for.
                        i.e. see examples above

Example:

java -jar jarscan.jar -dir C:\Folder\To\Search -showProgress -class GenericServlet

Filename: searchForFiles.py

import os, zipfile, glob, sys

def main():
    searchFile = sys.argv[1] #class file to search for, sent from batch file below (optional, see second block of code below)
    listOfFilesInJar = []
    for file in glob.glob("*.jar"):
        archive = zipfile.ZipFile(file, 'r')
        for x in archive.namelist():
            if str(searchFile) in str(x):
                listOfFilesInJar.append(file)

    for something in listOfFilesInJar:
        print("location of "+str(searchFile)+": ",something)

if __name__ == "__main__":
    sys.exit(main())

You can easily run this by making a .bat file with the following text (replace "AddWorkflows.class" with the file you are searching for):

(File: CallSearchForFiles.bat)

@echo off
python -B -c "import searchForFiles;x=searchForFiles.main();" AddWorkflows.class
pause

You can double-click CallSearchForFiles.bat to run it, or call it from the command line "CallSearchForFiles.bat SearchFile.class"

I know this is an old question but...
I had the same issue, so If someone is looking for a very simple solution for windows - there is a software named Locate32 Just put jar as file extension
And containing the class name
It finds the file within seconds.
