How To Install IntelliJ IDEA for Java on Ubuntu

IntelliJ IDEA is the smartest IDE for Java development. It's also the base of the official Android IDE i.e. Android Studio used for Android mobile application development. This tutorial provides all the steps required to install IntelliJ Idea on the popular Linux based system i.e. Ubuntu 18.04 LTS for Java development. The same installation can be used for Android application development using either Java or Kotlin. The steps should be the same for other distributions of Linux systems.


It assumes that Java is already installed on the system. You may also be interested in How To Install OpenJDK 12 On Ubuntu and How To Install Java 11 On Ubuntu.

The IntelliJ IDEA provides two different installers i.e. Ultimate and Community. The Ultimate edition is commercial version whereas the Community edition can be used for free. This tutorial shows the steps required to install the Community edition. The differences between both the editions are shown in Fig 2.


Intellij IDEA Editions

The Community Edition provides essential features required to develop Java applications. It supports Java, Kotlin, Groovy, Scala, Android, Maven, Gradle, SBT, Git, Svn, and Mercurial out of the box. The Ultimate edition also provides more advanced features including Perforce, JavaScript, TypeScript, Database Tools, Duplicates Detection, and supports frameworks including Spring, Play, Grails, etc.


Install IntelliJ IDEA


In order to install the Community Edition downloaded in the previous section, extract the download to the desired location. Make sure that the disk has at least 2 GB of free space since the installation will consume approx 1.1 GB of the available disk space. The steps remain the same for the Ultimate Edition.


Navigate to the bin directory of the extract as shown in Fig 3.

Create Desktop Shortcut


In this step, we will install the GNOME panel and use the same to create a desktop shortcut to execute the IDE installed by us in previous steps.


# Refresh packages indexes
sudo apt-get update

# Install GNOME Panel
sudo apt-get install --no-install-recommends gnome-panel

# Create Desktop icon
gnome-desktop-item-edit ~/Desktop/ --create-new


Now configure the IDE desktop shortcut as shown in Fig 4. We will use the IntelliJ IDEA icon available in the root of the installation directory as highlighted in Fig 3.
