How to Install Eclipse IDE on Ubuntu 20.04

Eclipse IDE is written in Java. It mainly consists of a base ‘Workspace’ and a plug-in system so that we can add more features to it through plugins and extend the functionality of the IDE.

You can easily combine multiple languages support and other features into any of our default packages, and the Eclipse Marketplace allows for virtually unlimited customization and extension.

Eclipse works on all the major platforms including Windows, Mac OS, Linux, etc. and boasts of powerful features that can be used to develop full-fledged projects.

This IDE application is famous for our Java Integrated Development Environment (IDE) and defined as platform for developing the computer-based applications using various programming language like JAVA, Python, C/C++, Ruby, We have a number of pretty cool IDEs, including our C/C++ IDE, JavaScript/TypeScript IDE, PHP IDE, and more.

Features Of Eclipse IDE

  • Almost everything in Eclipse is a plugin.
  • Supports various source knowledge tools like folding and hyperlink navigation, grading, macro definition browser, code editing with syntax highlighting.
  • We can extend the functionality of Eclipse IDE by adding plugins to the IDE, maybe for additional programming language or version control system or UML.
  • Eclipse has a wonderful user interface with drag and drop facility for UI designing.
  • Provides excellent visual code debugging tool to debug the code.
  • Java Eclipse IDE has a JavaDoc facility using which we can automatically create documentation for classes in our application.
  • Supports project development and administered framework for different toolchains, classic make framework, and source navigation.
  • Develop your software wherever you go. It’ll be there, in the cloud, right where you left it. Use your browser to develop with hosted workspaces or install desktop packaging to experience a modern development environment for Java, JavaScript, CSS, and HTML.
  • Extend the desktop and web-based IDEs by writing your own plug-ins using the Plug-in Development Environment (PDE), or mash up features to build the web IDE of your dreams.
  • An impressive collection of tools can be easily installed into your Eclipse desktop IDE, including GUI builders and tools for modeling, charting and reporting, testing, and more.
  • The testing can be done easy using the Eclipse IDE. The debugging process can be run smoothly for finding the bugs and threats in the application. The testing job can be run to find the threats so that application can be developed smoothly.
  • The platform also supports JPA tooling and JSF tooling, web service development and also supports to edit the XML files. In the platform the server view tab is available in which application can be deployed in any server as per user requirements.

Advantages and Disadvantages

Every application has some advantages and disadvantages. Here we have listed our observations on Eclipse IDE.

Pros:

  • Eclipse is free.
  • Simple UI for development, So it’s easy to find everything you need for coding
  • Boot up time is short compared to other IDE.
  • Very much suitable for managing large projects.
  • Multiple languages support
  • Lots of debugging features
  • Lots of plugins and integrations, as it’s open-source
  • Auto-completion saved a lot of time for developers
  • GIT integration

Cons:

  • Extensibility is not as good as IntelliJ
  • Not prepared for other languages than Java
  • It uses more resources than some other IDEs(Memory Hunger). Application lags when the project is big. Even it crashes on loading big projects.
  • Setting up of eclipse is a tad tiresome. If you are not used to use this IDE, it will be hard to understand the project explorer.

Which IDE do you develop with?

The graph here is consistent with other recent surveys: IntelliJ passing Eclipse in the last one to two years, and Apache NetBeans staying at around 10% of the market.

The 45% total votes of IntelliJ consist of 32% IntelliJ IDEA Ultimate Edition (the paid version), 11% IntelliJ Community Edition (the free version), and 2% Android Studio users.

The Eclipse category includes Eclipse STS, JBoss tools, Rational Application Developer and other Eclipse-based tools.

This article explains How to install Eclipse IDE on Ubuntu 20.04.

Installing the Default Java runtime environment (JRE)

Eclipse is a Java-based application and like I mentioned in minimum system requirements, we have to install Java Runtime Environment first.

The easiest option for installing Java is to use the version packaged with Ubuntu. By default, Ubuntu 20.04 includes Open JDK 11, which is an open-source variant of the JRE and JDK.

To install this version, first update the package index:

$ sudo apt update

Next type the following command to check whether Java is already installed on your system.

$ java -version

If Java is not currently installed, execute the following command to install the default Java Runtime Environment (JRE), which will install the JRE from OpenJDK 11.

$ sudo apt install default-jre

Installing Eclipse IDE as a Snap Package

A snap package is a type of universal Linux package that you can enjoy irrespective of the distro. Its an self-contained software packages that include the binary all dependencies needed to run the application.

All you need is the snap service pre-configured, In the case of Ubuntu 20.04, it comes with snap pre-installed.

If snapd package is not already installed then you can install it by running following command.

$ sudo apt install snapd

Note: Snap packages can be installed from either the command-line or via the Ubuntu Software application.

This is actually the Snap version of the Eclipse IDE. It can be used on any Linux distribution that has Snap support.

Open your terminal (Ctrl+Alt+T) and execute the following command to download and install the Eclipse snap package on your system.

$ sudo snap install --classic eclipse

On successful installation of Eclipse, you should see the following output.

Output:
eclipse 2019-03 from Snapcrafters installed

That’s It. Now you can open the Eclipse IDE application with the help of Activities search bar.

Starting Eclipse IDE

In the Activities search bar type “Eclipse” and click on the icon to launch the application.

When you start Eclipse for the first time, a window like the following will appear asking you to select a Workspace directory.

The default directory should be fine. Click Launch to proceed.

Note: Check the checkbox “Use this as the default and do not ask again” to make this location as default.

That’s It. Here is the Welcome screen of Eclipse IDE application.
