Answer 1

There are two enviroment_variables which point to different JREs (java runtime enviroment). Jenkins do not know which of them he should use.

probably you have set an enviroment_variable in Jenkins, where to find an JRE. But at the same time, you OS on which the jenkins is runnung, has also an enviroment_variable, which points to other location where to find the JRE.

Its up to you which of them you want to remove.

Answer 2

Try building your project like this, in two steps:

./gradlew prepareDebugDependencies
./gradlew assembleDebug

See https://github.com/evant/gradle-retrolambda/issues/105 for the discussion about the reason for this.

Also (helpful for other, maybe), make sure you have set up your environment variables similar to this:

export JAVA7_HOME=/usr/lib/jvm/java-7-oracle
export JAVA8_HOME=/usr/lib/jvm/java-8-oracle
export JAVA_HOME=$JAVA7_HOME
