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。

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

使用这个. .你可以在类路径..中找到任何文件。保证. .

import java.net.URL;
import java.net.URLClassLoader;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public class FileFinder {

    public static void main(String[] args) throws Exception {

        String file = <your file name>;

        ClassLoader cl = ClassLoader.getSystemClassLoader();

        URL[] urls = ((URLClassLoader)cl).getURLs();

        for(URL url: urls){
            listFiles(file, url);
        }
    }

    private static void listFiles(String file, URL url) throws Exception{
        ZipInputStream zip = new ZipInputStream(url.openStream());
          while(true) {
            ZipEntry e = zip.getNextEntry();
            if (e == null)
              break;
            String name = e.getName();
            if (name.endsWith(file)) {
                System.out.println(url.toString() + " -> " + name);
            }
          }
    }

}

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

你可以使用locate和grep:

locate jar | xargs grep 'my.class'

确保在使用locate之前运行updatedb。
