Eclipse可以做到这一点，只需创建一个(临时的)项目，并将您的库放在项目类路径上。然后你可以很容易地找到课程。

我想到的另一个工具是Java反编译器。它可以一次打开很多罐子，还可以帮助查找类。

grep -l "classname" *.jar

告诉你罐子的名字

find . -name "*.jar" -exec jar -t -f {} \; | grep  "classname"

给你类的包

要在一个jar文件夹(及其子文件夹)中找到一个类: 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

例子:

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

不知道为什么这里的脚本从来都不适合我。如此:

#!/bin/bash
for i in *.jar; do jar -tf "$i" | grep $1 | xargs -I{} echo -e "$i : {}" ; done

不久前，我专门为此写了一个程序:https://github.com/javalite/jar-explorer
