Pom looks like this:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.stchome.maven.mojo</groupId>
<version>1.0</version>
<artifactId>test</artifactId>
<packaging>pom</packaging>
<modules>
<module>extract-war</module>
<module>helloUser</module>
</modules>
</project>
I suspect this has been fixed for a long time now (since I know I've looked at that piece of code before regarding a NPE), but I've added an extra null check on the only value that could possibly be null. Also added a unit test for a project that references another project which is not in the list.
