Then i added Java_home
RUN apt-get update &&

apt-get install -y ant &&
apt-get clean &&
rm -rf /var/lib/apt/lists/ &&
rm -rf /var/cache/oracle-jdk8-installer;
enter code here
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64/ RUN export JAVA_HOME
**But still job run successfully but my requirements is not satisfied . Can any one tell me to install opencv with java_home 8
