Install Eclipse IDE on Rocky Linux 9 [Step-by-Step]

Eclipse is an open source(Eclipse Public License) and free integrated development environment. Although its main focus is on Java and Java-related technologies, it is also used for different languages such as C and Python, thanks to its flexible structure.

We will install this application, which can be installed on Windows, Mac OS X, Solaris operating systems and Linux distributions, on Rocky Linux 9.

 

Different methods to install Eclipse

Since Eclipse is a desktop application with a graphical interface, it must have a GUI in your operating system.  If your Rocky Linux 9 operating system does not have a GUI, install the GUI with the following commands:

[root@localhost foc]# dnf -y groupinstall "Server with GUI"
[root@localhost foc]# systemctl set-default graphical

After the above operations, the system is rebooted:

[root@rocky9 foc]# reboot now

We will describe the Eclipse installation in 2 ways:

• Install with Eclipse Installer
• Install with SNAP

 

Method-1 Install with Eclipse Installer

Login from the graphical interface and enter the terminal application. Then, the file with the extension ".tar.gz" for Linux systems is downloaded from the Eclipse official address:

[foc@localhost ~]$ wget https://ftp.fau.de/eclipse/oomph/epp/2022-09/R/eclipse-inst-jre-linux64.tar.gz

The tar compressed file is extracted:

[foc@localhost ~]$ tar -xf eclipse-inst-jre-linux64.tar.gz

Change to the eclipse-installer directory:

[foc@localhost ~]$ cd eclipse-installer/

Then the installer application is run:

[foc@localhost eclipse-installer]$ ./eclipse-inst

After this step, complete the installation by following the screens below:

Method-2 Install with SNAP

Activate the epel repository for Snap software packaging and distribution system setup:

[foc@localhost ~]$ sudo dnf -y install epel-release

Many EPEL packages require the CodeReady Builder (CRB) repository.
It is recommended that you run /usr/bin/crb enable to enable the CRB repository.

Enable the snapd socket:

[foc@localhost ~]$ sudo systemctl enable --now snapd.socket
Created symlink /etc/systemd/system/sockets.target.wants/snapd.socket → /usr/lib/systemd/system/snapd.socket.

Link snap for ease of use:

[foc@localhost ~]$ sudo ln -s /var/lib/snapd/snap /snap

Reboot the system for the changes to take effect:

[foc@localhost ~]$ sudo reboot

After the reboot, the last step is to install the eclipse classic version:

[foc@localhost ~]$ sudo snap install eclipse --classic
[sudo] password for foc:
2022-10-02T22:50:56+03:00 INFO Waiting for automatic snapd restart...
eclipse 2022-06 from Snapcrafters installed

When you call the application from the menu, the following version will greet you.

We have installed Eclipse Classic version from Snap repositories.

 

Summary

Although the version with Snap was a little behind, it was a stable and easy installation. Installation with the Eclipse installer provided the current version installation, but required a little more manual processing.

We have presented 2 different methods for installing Eclipse on Rocky Linux 9. We hope it will be useful.
