Build Identifier: 201111221000

The m2e plugin fails with a NullPointerException when the "Update project configuration..." action is selected from the Maven context menu on a project in Eclipse. 
This happens when there is a resource in pom.xml with a relative directory path outside of the maven project. Like:
<resource>
  <directory>../another-module/src/main/resource</directory>
</resource>
It also happens when the the ${basedir} maven property is used in the directory definition:
<resource>
  <directory>${basedir}/../another-module/src/main/resource</directory>
</resource>


Possible workaround to prevent the NPE is to use the following definition:
<resource>
  <directory>${project.build.directory}/../../another-module/src/main</directory>
</resource>


Reproducible: Always

Steps to Reproduce:
1. Define a resource in your pom.xml which is outside of your maven project (see the Details section) - for example a file from an another maven project module
2. Select the "Maven -> Update project configuration..." context menu on the project
3. The m2e fails with the reported NPE
