Overview

Maven is able to access environment variables in its configuration files by specifying the environment variable using the following format:

${env.SOME_VARIABLE}

Example of specifying a local filesystem repository:

<repository>
  <id>jboss-eap-repository-6.4.0</id>
  <url>file://${env.RUNTIME_DIR}/jboss-eap-6.4.0.GA-maven-repository</url>
</repository>

Environment variables specified as such will be de-referenced in pom.xml and settings.xml.
