destFileName not used by maven-dependency-plugin ?

Question

I'm sure this was working!

I have a maven dependency plugin config to put a java service wrapper into a particular folder in an appassembler target folder.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <configuration>
        <artifactItems>
            <artifactItem>
                <groupId>org.tanukisoftware</groupId>
                <artifactId>wrapper</artifactId>
                <version>3.2.1</version>
                <classifier>${target.arch.classifier}</classifier>
                <type>jar</type>
                <overWrite>true</overWrite>
                <outputDirectory>${project.build.directory}/appassembler/jsw/projectnamehere/lib</outputDirectory>
                <destFileName>wrapper-${target.arch}.dll</destFileName>
            </artifactItem>
            </artifactItem>
        </artifactItems>
    </configuration>
</plugin>

But it gets written as wrapper.dll (which is the filename in the repo). target.arch is set to "windows-x86-32".

Here's part of the log file:

I see that you are using dependency:unpack but this goal (logically) doesn't support destFileName (a destination filename doesn't really make sense when unpacking files).

In your case, either use the "final name" when packaging your dll. Or do some post processing using the Maven AntRun Plugin to rename the file.
