Installing Gradle

To install Gradle, you will have to download the compiled binaries from the https://gradle.org/gradle-download/ website.

Again, I'd like to emphasize the importance of checking the download integrity using checksums. I have given a detailed way to do it in the section about Ant installation.
Unfortunately, the Gradle website does not provide the checksum values for the downloadable files.

Gradle is downloadable in the ZIP format. To unpack the file, you will have to use the unzip command:

    $ unzip gradle-3.3-bin.zip

The created subdirectory is the usable binary distribution of Gradle. Usually, I move it under ~/bin, making it available only for my user on OS X. After that, you should add the bin directory of the installation to the PATH. To do that, you should edit the ~/.bashrc file and add the following lines:

export GRADLE_HOME=~/bin/gradle-3.3/ 
export PATH=${GRADLE_HOME}bin:$PATH

Then, restart the terminal application, or just type . ~/.bashrc and test the installation of Gradle, typing the following:

    $ gradle -version

We get to the following output, as can be seen in this screenshot:
