I'm not sure but I think that the Maven Archiver (which is mainly used by plugins to handle packaging) can be configured to achieve this.
About the <addMavenDescriptor>
element, the Maven Archiver Reference says:
Whether the generated archive will contain these two Maven files:
- The pom file, located in the archive in
META-INF/maven/${groupId}/${artifactId}/pom.xml
- A
pom.properties
file, located in the archive in META-INF/maven/${groupId}/${artifactId}/pom.properties
The default value is true.
So a pom configured like this should do the trick:
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.0</version>
<configuration>
<archive>
<addMavenDescriptor>false</addMavenDescriptor>
</archive>
</configuration>
</plugin>
...
</plugins>
</build>
...
</project>
