maven-assembly doesn't support war format
-----------------------------------------
Key: MNG-1274
URL: http://jira.codehaus.org/browse/MNG-1274
Project: Maven 2
Type: Bug
Components: maven-assembly-plugin
Versions: 2.0
Reporter: Jerome Lacoste
Trying to use the assembly plugin to repackage a war, I got the exception
below. The functionality was needed to implemented multi-webstart application
deployment in relation to the Webstart Plugin [1]
It fails miserably because of the missing webxml attribute required by the
WebArchiver, triggered because the specified format is war.
I was told on #maven that the assembly is not meant to package war. I don't see
why it couldn't :) So I mailed on @users [2]. Someone also asked for similar
funcionality [3].
So repackaging a war is clearly an required functionality.
Should we consider the assembly plugin one way to implement this feature, and
this is issue is indeed real?
Or should I take another approach, like move the assembly plugin execution as
part of an earlier phase (e.g. process-resources) inside the war project ?

Here's my assmbly descriptor:
<assembly>
<id>main</id>
<formats>
<format>war</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<outputDirectory>/</outputDirectory>
<includes>
<include>myproject:webapp</include>
</includes>
<unpack>true</unpack>
<scope>runtime</scope>
</dependencySet>
<dependencySet>
<outputDirectory>webstart</outputDirectory>
<includes>
<include>myproject:webstart1</include>
</includes>
<unpack>true</unpack>
<scope>runtime</scope>
</dependencySet>
</dependencySets>
</assembly>
and here's a part of the pom
<dependencies>
<dependency>
<groupId>myproject</groupId>
