# Kafka requires Java 8 in order to work properly. However, TravisCI's Ubuntu
# 16.04 ships with Java 11 and Java can't be set with `jdk` when python is
# selected as language. Ubuntu 14.04 does not work due to missing python 3.7
# support on TravisCI which does have Java 8 as default.
# show current JAVA_HOME and java version
echo "Current JAVA_HOME: $JAVA_HOME"
echo "Current java -version:"
which java
java -version
echo "Updating JAVA_HOME"
# change JAVA_HOME to Java 8
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64
echo "Updating PATH"
export PATH=${PATH/\/usr\/local\/lib\/jvm\/openjdk11\/bin/$JAVA_HOME\/bin}
echo "New java -version"
which java
java -version
