adding classpath using appassembler-maven-plugin for generating batch file - maven

Question

I am using appassembler from mojo. What I need to do is I have to add a perticular path of the project (say %BASEDIR%\resources) to class path, currently it is adding only %REPO% to the classpath. What changes should I do in my pom.xml. I have already provided below code.
<configurationDirectory>/some/path</configurationDirectory>
<includeConfigurationDirectoryInClasspath>true</includeConfigurationDirectoryInClasspath>
And the output batch file contains
set CLASSPATH=%BASEDIR%\\..\SOME\PATH;%REPO%\abc.jar
What I my final outcome should be...
set CLASSPATH=%BASEDIR%\\..\SOME\PATH;%REPO%\abc.jar;%BASEDIR%\resources
What changes should incorporate in my pom.xml for achieving above outcome?

This question is really useful im many cases such as allowing different jdbc drivers or user plugins. In my case I wanted to have a jrebel build and therefore I had to change the classpath and switch the jar by the build directory. But I think it is not very difficult to modify the script to fit your needs. Note that you need maven >= 3.0.3 because since maven 3.0.3 all your plugins are executed in the very same order as they are in your pom.xml. So put this plugin right after your appassembler plugin call.
