Resolution: Duplicate
> NullPointerException if no directory specified in webResources tag
> ------------------------------------------------------------------
>
> Key: MWAR-293
> URL: https://jira.codehaus.org/browse/MWAR-293
> Project: Maven 2.x WAR Plugin
> Issue Type: Bug
> Affects Versions: 2.2
> Environment: XP SP3, Eclipse Juno 4.2, Maven 3.0.4
> Reporter: guillaume
> Priority: Critical
>
> 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...
