yuicompressor maven plugin and maven-war-plugin

Question

I've been struggling with getting this plugin to play nicely with the maven-war-plugin for a couple of hours now and I thought it was time to ask for help. I have the plugin defined as follows:

<plugin>
    <groupId>net.alchim31.maven</groupId>
    <artifactId>yuicompressor-maven-plugin</artifactId>
    <version>1.3.0</version>
    <executions>
        <execution>
            <id>compressyui</id>
            <phase>process-resources</phase>
            <goals>
                <goal>compress</goal>
            </goals>
            <configuration>
                <nosuffix>true</nosuffix>
                <warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
                <jswarn>false</jswarn>
            </configuration>
        </execution>
    </executions>
</plugin>

If I remove nosuffix=true then I can see the compressed/minified -min.js files get into the war as expected, but with this flag on they are being overwritten by the maven-war-plugin (I'm assuming) when it builds the war file. I really need the file names to remain the same though ... does anyone have an idea of what I need to change in order to use the same filenames and still get the minified versions into the final war?

OK. I finally figured this out. You need to define a <webappDirectory> in the yuicompressor plugin that can then be referenced as a <resource> in the maven-war-plugin. In the example below I'm using <directory>${project.build.directory}/min</directory>

<plugin>
    <groupId>net.alchim31.maven</groupId>
    <artifactId>yuicompressor-maven-plugin</artifactId>
    <version>1.3.0</version>
    <executions>
        <execution>
            <id>compressyui</id>
            <phase>process-resources</phase>
            <goals>
                <goal>compress</goal>
            </goals>
            <configuration>
                <nosuffix>true</nosuffix>
                <warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
                <webappDirectory>${project.build.directory}/min</webappDirectory>
                <jswarn>false</jswarn>
            </configuration>
        </execution>
    </executions>
</plugin>
<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <executions>
        <execution>
            <id>default-war</id>
            <phase>package</phase>
            <goals>
                <goal>war</goal>
            </goals>
            <configuration>
                <warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
                <encoding>UTF-8</encoding>
            </configuration>
        </execution>
    </executions>
    <configuration>
        <warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
        <encoding>UTF-8</encoding>
        <webResources>
            <resource>
                <directory>${project.build.directory}/min</directory>
            </resource>
        </webResources>
    </configuration>
</plugin>

Just configure 'warSourceExcludes' on the WAR plugin.

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <warSourceExcludes>**/*.css,**/*.js</warSourceExcludes>
    </configuration>
</plugin>
