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

Unix

在Linux、其他Unix变体、Windows上的Git Bash或Cygwin上，使用jar(或unzip -v)、grep和find命令。

下面列出了与给定名称匹配的所有类文件:

for i in *.jar; do jar -tvf "$i" | grep -Hsi ClassName && echo "$i"; done

如果知道要搜索的整个Java存档列表，可以使用(符号)链接将它们全部放在同一个目录中。

或者使用find(区分大小写)查找包含给定类名的JAR文件:

find path/to/libs -name '*.jar' -exec grep -Hls ClassName {} \;

例如，要查找包含IdentityHashingStrategy的存档的名称:

$ find . -name '*.jar' -exec grep -Hsli IdentityHashingStrategy {} \;
./trove-3.0.3.jar

如果JAR可能在系统中的任何位置，并且locate命令可用:

for i in $(locate "*.jar");
  do echo "$i"; jar -tvf "$i" | grep -Hsi ClassName;
done

语法变化:

find path/to/libs -name '*.jar' -print | \
  while read i; do jar -tvf "$i" | grep -Hsi ClassName && echo "$i"; done 

窗户

打开命令提示符，切换到包含JAR文件的目录(或祖先目录)，然后:

for /R %G in (*.jar) do @jar -tvf "%G" | find "ClassName" > NUL && echo %G

下面是它的工作原理:

for /R %G in (*.jar) do - loop over all JAR files, recursively traversing directories; store the file name in %G. @jar -tvf "%G" | - run the Java Archive command to list all file names within the given archive, and write the results to standard output; the @ symbol suppresses printing the command's invocation. find "ClassName" > NUL - search standard input, piped from the output of the jar command, for the given class name; this will set ERRORLEVEL to 1 iff there's a match (otherwise 0). && echo %G - iff ERRORLEVEL is non-zero, write the Java archive file name to standard output (the console).

Web

使用扫描JAR文件的搜索引擎。

User1207523的脚本对我来说很好。这里有一个变体，使用find隐式搜索jar文件，而不是简单的展开;

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