How to Install Apache Groovy on Ubuntu Linux

Prepare Ubuntu

Before you install Apache Groovy on Ubuntu, it’s important to make sure your system’s software is up to date.

sudo apt update
sudo apt dist-upgrade
sudo apt autoremove

Running the commands above will update and remove obsolete packages from your system. It’s also a good idea to reboot the server after running them.

Install OpenJDK 8

Apache Groovy needs Java to run, so the next step is to install the OpenJDK 8 development kit on your Ubuntu system.

For this tutorial, we’re going to install OpenJDK.

To do that, run the commands below:

sudo apt update
sudo apt-get install openjdk-8-jdk openjdk-8-doc

After installing Java, you can verify it by running the commands below:

java -version

It should output something similar, as shown below:

Output:
openjdk version "1.8.0_242"
OpenJDK Runtime Environment (build 1.8.0_242-8u242-b08-0ubuntu3~18.04-b08)
OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode)

With Java installed and your system updated, you’re ready to install Apache Groovy.

Download Apache Groovy

Now that Java is ready, you can download and install Apache Groovy on Ubuntu using the simple SDKMAN install script.

To do that, run the commands below:

sudo apt install curl
curl -s get.sdkman.io | bash

Running that command will download any necessary supporting software (dependencies) and get your system ready for Groovy.

After a successful installation, you should get a similar message as shown below:

Extract script archive…
Install scripts…
Set version to 5.7.4+362 …
Attempt update of interactive bash profile on regular UNIX…
Added sdkman init snippet to /home/richard/.bashrc
Attempt update of zsh profile…
Updated existing /home/richard/.zshrc
All done!
Please open a new terminal, or run the following in the existing one:
source "/home/richard/.sdkman/bin/sdkman-init.sh"
Then issue the following command:
sdk help
Enjoy!!!

After running the commands above, run the commands below to set the Groovy environment.

source "$HOME/.sdkman/bin/sdkman-init.sh"

Finally, run the commands below to install Groovy.

sdk install groovy

That should install Groovy and show a similar message as below after the installation:

==== BROADCAST =================================================================

Setting groovy 3.0.2 as default.

That should do it!

After installing, you can check whether Groovy is installed by displaying its version number.

groovy -version

It should then display a similar line as shown below:

Groovy Version: 3.0.2 JVM: 1.8.0_242 Vendor: Private Build OS: Linux

This is how to install Apache Groovy on Ubuntu!

To launch Groovy, run the command below:

groovysh

That should open Groovy shell.
