Grep Jars For Package Or Class

05.03.2005

| 8448 views |

        Grep a bunch of jars for a certain package or class or expression:

find /path/to/directory -type f -name '*.jar' -print0 | xargs -n1 -0i sh -c 'jar tf "{}" | grep -q query && echo "{}"'


E.g.

find ~/soft/java/maven-repository -type f -name '*.jar' -print0 | xargs -n1 -0i sh -c 'jar tf "{}" | grep -q org.apache && echo "{}"'

Here's my version of findClass shell script. Examples findClass java.lang.String findClass DataSourceRealm /usr/local/tomcat/{server,shared,common}/lib/*.jar


#!/bin/bash
class=`echo $1| tr . /`
shift
allDirs="$(echo "$@" $CLASSPATH| perl -F: -ane 'print join(" ",@F);')"
printf -- "---- Searching for %s in %s\n" "$class" "$allDirs"
for dir in $allDirs; do
    printf -- "---- Searching in %s\n" "$dir"
    case $dir in
        *.zip)
            unzip -v $dir | grep $class
            ;;
        *.jar)
            jar -tf $dir | grep $class
            ;;
        *)
            find $dir -print | grep $class
            ;;
    esac
done
