Why jar file imaged from Docker is corrupted?

I downloaded the jar file (jenkins-cli.jar) using Docker using curl. Using command:

RUN curl --insecure -O http://192.168.99.100:8080/jnlpJars/jenkins-cli.jar

This is the Dockerfile which copies the manually downloaded jar file and also file downloading.

FROM ubuntu:14.04
# Install Java.
RUN \
  echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | debconf-set-selections && \
  apt-get update && \
  apt-get upgrade -y && \
  apt-get install -y  software-properties-common && \
  add-apt-repository ppa:webupd8team/java -y && \
  apt-get update && \
  apt-get install -y oracle-java8-installer && \
  rm -rf /var/lib/apt/lists/* && \
  rm -rf /var/cache/oracle-jdk8-installer

# Define commonly used JAVA_HOME variable
ENV JAVA_HOME /usr/lib/jvm/java-8-oracle

#Install dependencies
RUN apt-get -y update  && \
    apt-get -yqq --no-install-recommends install bash git bzip2 curl unzip && \
    apt-get update

EXPOSE 8080
VOLUME /jenkins

ENV JENKINS_URL "http://192.168.99.100:8080"    
ENV PRIVATE_KEY "C:\Users\himn\.ssh\id_rsa" 
COPY jenkins-cli.jar /jenkins-cli.jar 
RUN curl -H "Accept: application/zip"  http://192.168.99.100:8080/jnlpJars/jenkins-cli.jar -o /opt/jenkins-cli.jar
VOLUME /ssh
ENTRYPOINT ["bash"]

I tried file command on both as it mentioned in comment and following is the output: root@e31bbf40f650:/# file jenkins-cli.jar(copied jar file) jenkins-cli.jar: Zip archive data, at least v1.0 to extract

root@e31bbf40f650:/opt# file jenkins-cli.jar(jar file which downloaded when i build image) jenkins-cli.jar: HTML document, ASCII text, with CRLF, LF line terminators

Output of jenkins-ci.html using less command.

root@e31bbf40f650:/opt# less jenkins-ci.html
<!-- IE friendly error message walkround.
     if error message from server is less than
     512 bytes IE v5+ will use its own error
     message instead of the one returned by

2832 in the output of ls does not mean 2.83MB, it means 2832 bytes. I guess you should try renaming it to a filename ending in .html and open it in a web browser, or just viewing it with less. One of those two approaches should show you what the problem is.
