Ubuntu how add gradle to PATH

Step-by-step instructions

Gradle is a Java build system. It uses a clean, simple configuration syntax and is used by Android as the default build system. For API development, Gradle is supported by Spring.

Installation is quick and simple. We are going to install a private copy so that root permissions are not required during development.

Download Gradle

mkdir -p ~/opt/packages/gradle && cd $_

wget https://services.gradle.org/distributions/gradle-2.3-bin.zip

unzip gradle-2.3-bin.zip

Install and setup Gradle

Next, we will create a symlink that provides a shorter path to the specific Gradle version. The symlink will allow us to upgrade Gradle later without changing any other configuration.

ln -s ~/opt/packages/gradle/gradle-2.3/ ~/opt/gradle

Open your .profile file in vi, emacs, or gedit.

gedit ~/.profile

Paste the following at the bottom of your .profile file.

# Gradle
if [ -d "$HOME/opt/gradle" ]; then
    export GRADLE_HOME="$HOME/opt/gradle"
    PATH="$PATH:$GRADLE_HOME/bin"
fi

Finally, source your .profile and test gradle.

source ~/.profile

which gradle

gradle -version

Congratulations, you now have a working Gradle installation.
