Setup is similar as in the doc except:

retrolambda {
    jdk System.getenv("JAVA8_HOME")
    oldJdk System.getenv("JAVA7_HOME")
    javaVersion JavaVersion.VERSION_1_7
}

Environment variables are set to: /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home respectively.
