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?

Answer 1

The approach I use is a bit different.

First, I've configured my IDE to run mvn process-resources before the compilation/packaging. This way the files are created before the war is assembled.

It is very important to set <nosuffix>false</nosuffix> and <outputDirectory>${basedir}/src/main/resources/</outputDirectory> so the files can be created in the same directory without replacing your original source files.

 <plugin>
    <groupId>net.alchim31.maven</groupId>
    <artifactId>yuicompressor-maven-plugin</artifactId>
    <version>1.3.2</version>
    <configuration>
        <preProcessAggregates>false</preProcessAggregates>
        <excludes>
            <exclude>**/*-min.js</exclude>
            <exclude>**/*.min.js</exclude>
            <exclude>**/*-min.css</exclude>
            <exclude>**/*.min.css</exclude>
        </excludes>
        <jswarn>false</jswarn>
        <nosuffix>false</nosuffix> <!-- VERY IMPORTANT WILL REPLACE YOUR FILES IF YOU SET nosuffix TO TRUE OR DONT SET IT AT ALL -->
        <outputDirectory>${basedir}/src/main/resources/</outputDirectory> <!-- by default the plugin will copy the minimized version to target directory -->
        <failOnWarning>false</failOnWarning>
    </configuration>

    <executions>
        <execution>
            <id>compress_js_css</id>
                <phase>process-resources</phase>
            <goals>
                <goal>compress</goal>
            </goals>
        </execution>
    </executions>
</plugin>
