    Fix Version/s: 2.2-beta-2

I just enabled this feature, with a slightly different solution. What you're really talking about is a standard assembly descriptor for more than one project. If your descriptor were built into the assembly plugin, it'd simply be a standard descriptorRef configuration. To enable this sort of behavior for standardized descriptors outside the assembly plugin itself, you can do the following:

Define a project that contains the standardized descriptor. Here's an example layout based on the integration test in:

http://svn.apache.org/repos/asf/maven/plugins/maven-assembly-plugin/src/it/basic-features/assemblyDescriptor-artifact 

The pom.xml looks like this:

{code:xml}
<project>
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>org.test</groupId>
    <artifactId>assemblyDescriptor-artifact</artifactId>
    <version>1</version>
  </parent>
  
  <artifactId>descriptor</artifactId>
  <packaging>assembly-descriptor</packaging>
  <build>
    <extensions>
      <extension>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-assembly-artifact-types</artifactId>
        <version>2.2-beta-2-SNAPSHOT</version>
      </extension>
    </extensions>

    <plugins>
      <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>2.2-beta-2-SNAPSHOT</version>
      </plugin>
    </plugins>
  </build>
</project>
{code}

The assembly descriptor is in src/main/resources/assembly-descriptor.xml by default, and looks like this in the example:

{code:xml}
<assembly>
  <id>fromArtifact</id>
  <formats>
    <format>dir</format>
  </formats>
  <includeBaseDirectory>false</includeBaseDirectory>
  <files>
    <file>
      <source>src/config/a/file.txt</source>
      <outputDirectory>a</outputDirectory>
      <filtered>true</filtered>
    </file>
    <file>
      <source>src/config/b/file.txt</source>
      <outputDirectory>b</outputDirectory>
      <destName>file.txt</destName>
      <filtered>true</filtered>
    </file>
  </files>
</assembly>
{code}

(so, pretty much normal).

You can use the standard descriptor after installing it into the repository with a pom.xml like the following:

{code:xml}
<project>
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>org.test</groupId>
    <artifactId>assemblyDescriptor-artifact</artifactId>
    <version>1</version>
  </parent>
  
  <artifactId>assembly</artifactId>
  
  <build>
    <filters>
      <filter>a.properties</filter>
    </filters>
        
    <plugins>
      <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>2.2-beta-2-SNAPSHOT</version>
        <configuration>
          <descriptors>
            <descriptor>org.test:descriptor:1</descriptor>
          </descriptors>
        </configuration>
        <executions>
          <execution>
            <id>assembly</id>
            <phase>package</phase>
            <goals>
              <goal>single</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>
{code}

Note the extension in the standard descriptor's pom.xml.

> Above descriptor works fine only if I have defined a descriptor file on the src/main/assembly folder for each sub-folder1, sub-folder2, etc. 
> It would be great if maven supports me in defining a common assembly descriptor and can be shared by all the sub modules from a common location.
