Jenkins-cli.jar is corrupted when I run docker file in bash - docker

Question

I need to build the dockerfile that downloads jenkins.war and through it jenkins-cli.jar need to be downloaded.
I have conf.xml also to configure it.**
Then I need that image to run in the bash, which needs to run that jar file commands.
Here is the code:
FROM ubuntu:14.04
RUN apt-get update && \
apt-get upgrade -y && \
apt-get install -y software-properties-common && \
add-apt-repository ppa:webupd8team/java -y && \
apt-get update && \
echo oracle-java7-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections && \
apt-get install -f -y oracle-java8-installer && \
apt install -y default-jre curl wget git nano; \
apt-get clean
# Install dependencies
RUN apt-get -y update && \
apt-get -yqq --no-install-recommends install git bzip2 curl unzip && \
apt-get update
ENV JAVA_HOME /usr
ENV PATH $JAVA_HOME/bin:$PATH
# copy jenkins war file to the container
ADD http://mirrors.jenkins.io/war-stable/2.107.1/jenkins.war /opt/jenkins.war
RUN chmod 644 /opt/jenkins.war
ENV JENKINS_HOME /jenkins
# configure the container to run jenkins, mapping container port 8080 to that host port
RUN mkdir /jenkins/
RUN echo 2.107.1 > /jenkins/jenkins.install.UpgradeWizard.state
RUN echo 2.107.1 > /jenkins/jenkins.install.InstallUtil.lastExecVersion
CMD ["nohup","java", "-jar", "/opt/jenkins.war"]
EXPOSE 8080
VOLUME /jenkins
#COPY jenkins-cli.jar /jenkins/jenkins-cli.jar
#jenkins-cli installation
ENV JENKINS_URL "http://192.168.99.100:8080"
RUN curl --insecure http://192.168.99.100:8080/jnlpJars/jenkins-cli.jar \
--output /jenkins/jenkins-cli.jar
CMD ["java","-jar","/jenkins/jenkins-cli.jar","-noCertificateCheck","-noKeyAuth"]
Here is what im getting.
MY ASSUMPTION
Do I need to run along congf.xml?If yes , then HOW?
Do I need to be running jenkins.war instance in background??? HOW?
Thank you in advance

If you see the reference , I can find those comments.
There can only be one CMD instruction in a Dockerfile. If you list more than one CMD then only the last CMD will take effect.
in your dockerfile, there are multiple CMD commands. only the last one will be executed.
If you want to run multiple commands at once. try bash scripts. here is the example
#!/bin/bash
echo "Starting sshd"
exec /usr/sbin/sshd -D &
if [ -z "$1" ];
then
tail -f $HADOOP_INSTALL/logs/*
fi
