Our Maven 2 build job in Jenkins was created using the "maven2/3 project" template provided by the Maven 2 Project plugin. After installing the EnvInject plugin & configuring the "Prepare an environment for the run" settings at the job level, the job fails every time with the following error;

[EnvInject] - [ERROR] - SEVERE ERROR occurs: hudson.maven.MavenModuleSet cannot be cast to hudson.model.Project

Does EnvInject assume that the job is an instance of hudson.model.Project, which is a class? Is there a common interface that MavenModuleSet & Project both implement which could be used instead? Or a common ancestor super-class, e.g. hudson.model.AbstractProject?
