Install gradle on redhat/centos linux

install-gradle-centos.sh

# installs to /opt/gradle
# existing versions are not overwritten/deleted
# seamless upgrades/downgrades
# $GRADLE_HOME points to latest *installed* (not released)
gradle_version=2.9
wget -N https://services.gradle.org/distributions/gradle-${gradle_version}-all.zip
sudo unzip -foq gradle-${gradle_version}-all.zip -d /opt/gradle
sudo ln -sfn gradle-${gradle_version} /opt/gradle/latest
sudo printf "export GRADLE_HOME=/opt/gradle/latest\nexport PATH=\$PATH:\$GRADLE_HOME/bin" > /etc/profile.d/gradle.sh
. /etc/profile.d/gradle.sh
# check installation
gradle -v

Thanks for this. Small improvement though:

sudo printf "export GRADLE_HOME=/opt/gradle/latest\nexport PATH=\$PATH:\$GRADLE_HOME/bin" > /etc/profile.d/gradle.sh

should be

printf "export GRADLE_HOME=/opt/gradle/latest\nexport PATH=\$PATH:\$GRADLE_HOME/bin" | sudo tee /etc/profile.d/gradle.sh >/dev/null

Building on what others wrote, here is a small script that works on Centos 7 (always returns the latest version of gradle from the URL)

#!/bin/bash
cd /root
gradle_package=`curl -s http://services.gradle.org/distributions --list-only | sed -n 's/.*\(gradle-.*.all.zip\).*/\1/p' | egrep -v "milestone|rc" | head -1`
gradle_version=`ls ${gradle_package} | cut -d "-" -f 1,2`
mkdir /opt/gradle
wget -N http://services.gradle.org/distributions/${gradle_package}
unzip -oq ./${gradle_package} -d /opt/gradle
ln -sfnv ${gradle_version} /opt/gradle/latest
printf "export GRADLE_HOME=/opt/gradle/latest\nexport PATH=\$PATH:\$GRADLE_HOME/bin" > /etc/profile.d/gradle.sh
. /etc/profile.d/gradle.sh
hash -r ; sync
# check installation
gradle -v

Above script works on Fedora 23 👍

Yes, it works! Thx :)

If you don't have wget installed and want to stick with curl for the download as well, replace the wget line with:

curl -L -Of http://services.gradle.org/distributions/${gradle_package}

Fixed gradle_version determination in @fluffybastard version. Checked on CentOS 7.1

#!/bin/bash
cd /root
gradle_package=`curl -s http://services.gradle.org/distributions --list-only | sed -n 's/.*\(gradle-.*.all.zip\).*/\1/p' | egrep -v "milestone|rc" | head -1`
gradle_version=`echo ${gradle_package} | cut -d "-" -f 1,2`
mkdir /opt/gradle
curl -L -Of http://services.gradle.org/distributions/${gradle_package}
unzip -oq ./${gradle_package} -d /opt/gradle
ln -sfnv ${gradle_version} /opt/gradle/latest
printf "export GRADLE_HOME=/opt/gradle/latest\nexport PATH=\$PATH:\$GRADLE_HOME/bin" > /etc/profile.d/gradle.sh
. /etc/profile.d/gradle.sh
hash -r ; sync
# check installation
gradle -v

It became easy :
https://gradle.org/gradle-download/
Snippet:
Install with SDKMAN!

Get SDKMAN!
$ curl -s https://get.sdkman.io | bash

Open a new terminal and install Gradle
$ sdk install gradle 3.0

sudo printf "export GRADLE_HOME=/opt/gradle/latest\nexport PATH=$PATH:$GRADLE_HOME/bin" > /etc/profile.d/gradle.sh

I get
-bash: /etc/profile.d/gradle.sh: Permission denied

But im the root user and im using the sudo command

@AndrewKralovec

Try this:

printf "export GRADLE_HOME=/opt/gradle/latest\nexport PATH=\$PATH:\$GRADLE_HOME/bin" | sudo tee /etc/profile.d/gradle.sh

Thanks! It was very succinct info.

Instead of gradle -v I had to do /opt/gradle/bin/gradle -v
