List the classpath with guava

I wanna use some resources on my classpath and dont know the exact path to address them. I'll show this using an example with jquery.

I have dependency and want to use the jquery inside.

    <project ...>
        ...
        <dependencies>
            ...
            <dependency>
                <groupId>org.webjars</groupId>
                <artifactId>jquery</artifactId>
                <version>2.1.4</version>
            </dependency>
            ...
            <dependency>
                <groupId>com.google.guava</groupId>
                <artifactId>guava</artifactId>
                <version>18.0</version>
            </dependency>
            ...
            <dependency> // just for my convinience ;)
                <groupId>org.apache.commons</groupId>
                <artifactId>commons-io</artifactId>
                <version>1.3.2</version>
            </dependency>
            ...
        </dependencies>
    </project>

With this demo test:

import org.apache.commons.io.IOUtils;
import com.google.common.reflect.ClassPath;
import org.junit.Test;
import java.io.IOException;
import java.io.InputStream;
import java.io.StringWriter;
import java.net.URL;
import java.nio.file.Files;
import java.nio.file.Paths;

public class DemoTest {
    private static String readAsString(String name) throws IOException {
        ClassLoader classloader = DemoTest.class.getClassLoader();
        try (InputStream resourceAsStream = classloader.getResourceAsStream(name)) {
            if (resourceAsStream == null) {
                throw new IOException("resource not found:" + name);
            }
            StringWriter writer = new StringWriter();
            IOUtils.copy(resourceAsStream, writer);
            return writer.toString();
        }
    }

    @Test
    public void test() throws Exception {
        ClassPath.from(getClass().getClassLoader())
        .getResources()
        .stream()
        .filter(e -> e.getResourceName().contains("jquery.min.js"))
        .forEach(e-> {
            System.out.println("path       : " + e);
            System.out.println("first bytes: " + readAsString(e.getResourceName()).substring(0,10));
        });
    }
}

The output is:

path       : META-INF/resources/webjars/jquery/2.1.4/jquery.min.js
first bytes: /*! jQuery
