Creating generic assembly descriptor

["Rajasekaran, Vinoth (GE Healthcare)" <Vi...@med.ge.com>]

Hi,
 
I have a multi-project folders setup like
 
    root 
        |_ sub-folder1
        |_ sub-folder2
        |_ sub-folder3
        |_ etc   
 
Have a root pom.xml at the root folder level and in that I have defined 
<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
        <configuration>
            <descriptors>
                <descriptor>src/main/assembly/descriptor.xml
                </descriptor>
            </descriptors>      
        </configuration>
</plugin>
 
Above descriptor works fine if I have defined a descriptor file on the
src/main/assembly folder for each sub-folder1, sub-folder2, etc.
 
Contents of the descriptor looks like
<assembly>
  <id>dep</id>
  <formats>
    <format>zip</format>
  </formats>
  <includeBaseDirectory>false</includeBaseDirectory>
  <fileSets>
    <fileSet>
     <directory>sub-folder2/target</directory>
     ...
   
My questions are, 
1. How I can define one default descriptor at common location for all
the sub-folders.
2. What modifications would be required for root pom.xml and how should
I go about creating the generic default descriptor.
 
Thanks in advance,
Vinoth
