Answer 1

Use the system scope on a dependency:

  <dependency>
    <groupId>com.foo</groupId>
    <artifactId>foo</artifactId>
    <version>1.2.3</version>
    <scope>system</scope>
    <systemPath>${FOO_HOME}/lib/foo.jar</systemPath>
  </dependency>

The case above is also using an OS environment variable to the installation directory of the FOO software.
