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

这个在MinGW (windows bash环境)中工作得很好~ gitbash

把这个函数放到HOME目录下的.bashrc文件中:

# this function helps you to find a jar file for the class
function find_jar_of_class() {
  OLD_IFS=$IFS
  IFS=$'\n'
  jars=( $( find -type f -name "*.jar" ) )
  for i in ${jars[*]} ; do 
    if [ ! -z "$(jar -tvf "$i" | grep -Hsi $1)" ] ; then
      echo "$i"
    fi
   done 
  IFS=$OLD_IFS
}

我找到了这个新方法

bash $ ls -1  | xargs -i -t jar -tvf '{}'| grep Abstract
jar -tvf activation-1.1.jar
jar -tvf antisamy-1.4.3.jar

如果你想，你可以给ls -1 *.jar，或者用查找命令HTH Someone输入xargs。

还有两个不同的实用程序，称为“JarScan”，可以完全满足您的要求: JarScan (inetfeedback.com)和JarScan (java.net)

你可以在一个充满jar的目录中找到一个类，它带有一些shell:

寻找类“FooBar”:

LIB_DIR=/some/dir/full/of/jarfiles
for jarfile in $(find $LIBDIR -name "*.jar"); do
   echo "--------$jarfile---------------"
   jar -tvf $jarfile | grep FooBar
done

使用unzip (zipinfo)的bash脚本解决方案。在Ubuntu 12上测试。

#!/bin/bash

# ./jarwalker.sh "/a/Starting/Path" "aClassName"

IFS=$'\n'
jars=( $( find -P "$1" -type f -name "*.jar" ) )

for jar in ${jars[*]}
    do
        classes=( $( zipinfo -1 ${jar} | awk -F '/' '{print $NF}' | grep .class | awk -F '.' '{print $1}' ) )
        if [ ${#classes[*]} -ge 0 ]; then
            for class in ${classes[*]}
                do
                    if [ ${class} == "$2" ]; then
                        echo "Found in ${jar}"
                    fi
                done
        fi
    done
