Description

I would to exclude directories from the default web resources folder (src/main/webapp) and the documentation (http://maven.apache.org/plugins/maven-war-plugin/examples/adding-filtering-webresources.html) indicates that it can be done :

Here's another example of how to specify include and exclude patterns:

...
<configuration>
<webResources>
<resource>
<!-- the default value is ** -->
<includes>
<include>**/pattern1</include>
<include>*pattern2</include>
</includes>
<!-- there's no default value for this -->
<excludes>
<exclude>*pattern3/pattern3</exclude>
<exclude>pattern4/pattern4</exclude>
</excludes>
</resource>
</webResources>
</configuration>
...
But in this case, the plugin throws a NullPointerException : org.apache.maven.plugin.war.packaging.WarProjectPackagingTask (handleWebResources line 125).

Indeed, the null reference of resource.getDirectory() given to File constructor leads to a null pointer...
