How to Install Eclipse IDE on Ubuntu 20.04
Eclipse is one of the most popular open-source IDE (Integrated Development Environment) for software developers. It is popular for Java-based applications, also used for C/C++, PHP, and Perl and other web projects.
Eclipse is a really powerful IDE that supports many programming languages. It provides numerous plugins and extensions for enhancing the functionality of your Eclipse such as source code version control (git, svn), class diagram generator, GUI builder.
This tutorial will show you 2 methods to install Eclipse on Ubuntu 20.04 LTS machine.
Prerequisites
In order to install Eclipse IDE, you have to install JRE (Java Runtime Environment) on your Ubuntu machine:
To verify that Java was successfully installed, let’s run:
Install Eclipse by installer package [Method 1]
At the time of this writing, the latest version of Eclipse is: Eclipse IDE 2020-06. Eclipse can be downloaded via the browser on its official website https://www.eclipse.org/downloads/
By default, the installer package is downloaded into the directory ‘
/Downloads’ with name: ‘eclipse-inst-linux64.tar.gz’.
Or by using the wget command as:
Let’s extract the downloaded tarball file to the directory ‘/opt’ by running the following command:
In order to install Eclipse, launch the installer file ‘eclipse-inst’ by running the following command:
Eclipse packages window appears, let’s choose your favorite package IDE.
For example, select the Eclipse IDE for C/C++ Developers then click INSTALL
Next, you have to accept the Eclipse Foundation Software User Agreement.
Now, your Eclipse IDE will be installing.
After the installation has completed, Eclipse is ready to be launched.
Eclipse installation by snap [ Method 2]
Installing Eclipse by snap package manager is the handiest installation method to bring the Eclipse integrated development environment to your Ubuntu machine.
In order to install an old version of Eclipse, you can use the apt package manager:
Another simple way to install Eclipse IDE is using Ubuntu Software Center. Let’s open the software center and search for Eclipse then click the Install button.
Create launcher icon
Once the Eclipse is downloaded and installed successfully, you may need to create a shortcut to launch your IDE. Using your favorite editor to create a file named ‘eclipse.desktop’ and enter the following lines to it:
Please note that the paths in lines ‘Exec=’ and ‘Icon=’ are depended on your system. You can find the path in Exec line by running command:
Now, let’s enable the launcher icon:
That’s all. From now on, you can search for eclipse and launch it in the Applications center on your Ubuntu machine.
Conclusion
In this tutorial, we learned how to install the Eclipse IDE on Ubuntu 20.04. You can now begin to write your own codes to create many awesome applications with Eclipse.

Installed in /root/eclipse/parallel-2020-06/eclipse/eclipse
eclipse.desktop installed in /usr/share/applications/eclipse.desktop
But Eclipse is not found by the system (Ubuntu 20.04).
Great very clear instructions. I must be close.
Thanks for any help
Carl
Thanks for your good words.
Hello, some suggestions.
* You can also add locale to comment field, which is more useful then the name.
* From the installation directory, run ./eclipse -initialize to make it start faster.
* Check the desktop file with `desktop-file-verify eclipse.desktop’ before installation. It is easy to be some errors if not.
* One could also install with `desktop-file-install eclipse.desktop’ if one doesn’t want to look up where they should be stored.
* I usually add a short script in /usr/local/bin that launches the right version from /opt/Eclipse/eclipse-*/eclipse. So I rename the /opt/Eclipse/eclipse to the version number so I do remember which I have installed. I usually also make a symbolic link `ln -s eclipse eclipse-2020-12′ so I also reach it as the current one. Then it is easy to have old and new installed at the same time.
The script in /usr/local/bin/eclipse-base looks like this.
#!/bin/sh
#
# Make a link to this script, and it will try
# to start an eclipse in the same directory
#
# If it doesn’t exists, it just will fail.
exec /opt/Eclipse/`basename $0`/eclipse $*
Then I only make a soft or hard link from the version number to this base, like this:
$ ls -l eclipse*
lrwxrwxrwx 1 root root 12 sep 23 13:39 eclipse -> eclipse-base
lrwxrwxrwx 1 root root 12 sep 23 12:43 eclipse-2019-09 -> eclipse-base
lrwxrwxrwx 1 root root 12 sep 23 12:42 eclipse-2019-12 -> eclipse-base
lrwxrwxrwx 1 root root 12 sep 23 12:44 eclipse-2020-09 -> eclipse-base
-rwxrwxr-x 1 root root 191 sep 23 12:41 eclipse-base
$
Now I can easily start eclipse from command line, and based on the name, it choose right binary in /opt/Eclipes/*/eclipse to run.

Eclipse/Installation
Installing Eclipse is relatively easy, but does involve a few steps and software from at least two different sources. Eclipse is a Java-based application and, as such, requires a Java Runtime Environment or Java Development Kit (JRE or JDK) in order to run.
Note that on recent versions of Mac, a full JDK needs to be installed, not just a JRE; see instructions below.
Contents
Install a JVM
If you are using Eclipse to do Java development, or are on macOS, install a JDK. In all cases, Eclipse requires a 64-bit JVM
A Java Development Kit (JDK) includes many useful extras for Java developers including the source code for the standard Java libraries.
Regardless of your operating system, you will need to install some Java virtual machine (JVM). You may either install a Java Runtime Environment (JRE), or a Java Development Kit (JDK), depending on what you want to do with Eclipse. If you intend to use Eclipse for Java development, then you should install a JDK. If you aren’t planning to use Eclipse for Java development and want to save some disk space, install a JRE.
- If you’re using Windows, you may already have a JRE installed, but upgrading usually won’t hurt.
- If you’re using Mac, and you don’t have a JDK installed, you may get a bogus message from the OS stating that you should «install the legacy Java SE 6 runtime». Installing that will not solve the problem, because recent versions of Eclipse require a higher version. If you install just a JRE, and not a full JDK, that error message will persist. You must install a full JDK.
- If using Linux, read this
- GCJ (if you’re somehow still using it) will NOT work.

JRE/JDK Sources
There are several sources for a JRE/JDK. Here are some of the more common/popular ones (listed alphabetically):
Download Eclipse
Download Eclipse from the Eclipse Downloads Page.
There are several package choices. Note that you can install the features from any package into any other package. If you are, for example, planning to do mostly Java development and some C/C++ development, you should download the Eclipse IDE for Java Developers and then add the C/C++ development tools via the «Help > Install New Software. » menu option.
The download will be delivered as a compressed (i.e. a «.zip», or «.tar.gz») file. Decompress this file into the directory of your choice (e.g. «c:\eclipse» on Windows) and ensure you have full Read and Execute permissions. You can optionally create a shortcut of the executable file («eclipse.exe» on Windows, or «eclipse» on Linux).
Note that there is a known problem with the built-in decompression utility on all current versions of Windows. We recommend that you use a more robust decompression utility such as the open source 7zip when decompressing an Eclipse download. Some people report success when initially decompressing Eclipse into a root directory (e.g. c:\) and then moving it to a more appropriate home (e.g. c:\Program Files\Eclipse)
Configure Eclipse to use the JVM
It is strongly recommended to configure Eclipse with the specific JVM that you want. See the instructions at Eclipse.ini This is a very important step to be sure that Eclipse is using the JVM you intend and can’t be influenced by any other software that might alter your system. The JVM used to launch Eclipse has no affect on whether it can compile Java sources for other Java language versions.
Extending Eclipse
Use the Help > Install new software. menu option to add Kepler features to your Eclipse installation (you can, for example, use this option to add C/C++ development support). Additionally, you can tap into a vast collection of extensions provided by the Eclipse community and ecosystem via the Eclipse Marketplace Client (Help > Eclipse Marketplace). Note that not all Eclipse packages contain the Eclipse Marketplace Client.
Troubleshooting
Java was started but returned exit code = 13
If you’ve «installed» Eclipse but are having trouble getting it to run, the most likely cause is that you have not correctly specified the JVM for it to run under. You may need to edit the eclipse.ini file.
Another common mistake on Microsoft Windows is a mismatch between the «bittedness» of Eclipse and the JVM/JDK. This is the most frequent cause of an Error 13. 64-bit Eclipse requires a 64-bit JVM, and 32-bit Eclipse requires 32-bit JVM—you can not mix-and-match between 32-bit and 64-bit, so make sure the version of Eclipse you installed matches the JVM/JDK that you’re using to run it (and make sure you’re using eclipse.ini to specify the exact JVM used to run Eclipse, described above).
As a simple test, open a Command Prompt window, move to the directory that is pointed to by the -vm argument in your eclipse.ini, and run the intended java.exe with the -d32 switch to test if it supports 32-bit, or -d64 to test for 64-bit support. It’s often simplest to download a version of Eclipse that will work with whatever Java you already have installed.
To open «Eclipse» you need to install the legacy Java SE 6 runtime
On more recent versions of the Mac, if you don’t have a full JDK of an appropriately high version installed, the OS produces this bogus message. Installing any JRE will not eliminate this problem. A full JDK needs to be installed on the Mac.
Extraction requires a password or otherwise fails on Windows.
