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

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

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
