Using retrolambda in Android application being built using circleci as continuous integration cause some issues:

> Building 10%When running gradle with java 8, you must set the path to the old jdk, either with property retrolambda.oldJdk or environment variable JAVA5_HOME/JAVA6_HOME/JAVA7_HOME

The problem is you have to configure environment variables for Java_Home, Java7_Home, Java6_Home and etc in circleci virtual machine.
