Maven - Copy Some Dependency JARs into warSourceDirectory

问题

Can any Maven plugins copy one or more dependencies (although not all of them) of a .war project into its warSourceDirectory (src/main/webapp)?

I'm working on a Java web-app that will display an applet. I'd like the war project to pick the latest version of some jars (the applet's dependencies) and stick them in /src/main/webapp/, to save me having to copy them around the place.

I've thought about shading and uber-jar-ing the applet itself, but I'd like to split the jars up to save users having to download one massive jar when only one of the bits in it has changed.

Use for this dependency:copy from Maven Dependency Plugin.

Sample configuration

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.8</version>
<executions>
    <execution>
        <id>copy</id>
        <phase>compile</phase>
        <goals>
            <goal>copy</goal>
        </goals>
        <configuration>
            <artifactItems>
                <artifactItem>
                    <groupId>junit</groupId>
                    <artifactId>junit</artifactId>
                    <version>3.8.1</version>
                    <type>jar</type>
                    <overWrite>false</overWrite>
                    <destFileName>optional-new-name.jar</destFileName>
                </artifactItem>
            </artifactItems>
            <outputDirectory>${project.build.directory}/${project.artifactId}-${project.version}/</outputDirectory>
            <overWriteReleases>false</overWriteReleases>
            <overWriteSnapshots>true</overWriteSnapshots>
        </configuration>
    </execution>
</executions>

Copying files into src/main/webapp is bad idea. Copy file directly into target folder.
