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

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)

下面的脚本将帮助您

for file in *.jar
do
  # do something on "$file"
  echo "$file"
  /usr/local/jdk/bin/jar -tvf "$file" | grep '$CLASSNAME'
done

查找匹配给定字符串的jar:

找到。name \*.jar -exec grep -l YOUR_CLASSNAME {} \;

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);
            }
          }
    }

}
