Problem scenario
You want to use the same Bash script to install Apache Ant on CentOS/RedHat/Fedora, Debian/Ubuntu, or Linux SUSE. How do you install the latest version of Apache Ant on to any distribution of Linux?
Solution
Updated 4/8/21
With a "sudo bash" command, run a script with the following content (e.g., call the script below "installant.sh" and run "sudo bash installant.sh"):
#!/bin/bash
# Written by www.continualintegration.com
antversion=1.10.9 # Change this version as necessary
distro=$(cat /etc/*-release | grep NAME)
debflag=$(echo $distro | grep -i "ubuntu")
if [ -z "$debflag" ]
then # If it is not Ubuntu, test if it is Debian.
debflag=$(echo $distro | grep -i "debian")
echo "determining Linux distribution..."
else
echo "You have Ubuntu Linux!"
fi
rhflag=$(echo $distro | grep -i "red*hat")
if [ -z "$rhflag" ]
then #If it is not RedHat, see if it is CentOS or Fedora.
rhflag=$(echo $distro | grep -i "centos")
if [ -z "$rhflag" ]
then #If it is neither RedHat nor CentOS, see if it is Fedora.
echo "It does not appear to be CentOS or RHEL..."
rhflag=$(echo $distro | grep -i "fedora")
fi
fi
if [ -z "$rhflag" ]
then
echo "...still determining Linux distribution..."
else
echo "You have a RedHat distribution (e.g., CentOS, RHEL, or Fedora)"
yum -y install java-1.8.0-openjdk*
JAVA_HOME=/usr/lib/jvm/jre-1.8.0-openjdk
echo 'export JAVA_HOME=/usr/lib/jvm/jre-1.8.0-openjdk' >> ~/.bashrc
source ~/.bashrc
source /etc/environment
fi
if [ -z "$debflag" ]
then
echo "...still determining Linux distribution..."
else
echo "You are using either Ubuntu Linux or Debian Linux."
apt-get -y update # This is necessary on new AWS Ubuntu servers.
apt -y install openjdk-9-jre-headless
apt -y install openjdk-11-jre-headless
apt-get -y remove ant
fi
suseflag=$(echo $distro | grep -i "suse")
if [ -z "$suseflag" ]
then
if [ -z "$debflag" ]
then
if [ -z "$rhflag" ]
then
echo "*******************************************"
echo "Could not determine the Linux distribution!"
echo "Installation aborted. Nothing was done."
echo "******************************************"
exit
fi

zypper -n install java-1_8_0-openjdk
