How to Install The Latest Eclipse 4.7.3a in Ubuntu 18.04

Last updated: May 30, 2018

The latest release of Eclipse IDE now is quite easy to install in Ubuntu 16.04, and Ubuntu 18.04 since it’s made into snap package.

Snap is an universal Linux package format. It ships with most run-time libraries so it’s normally large in file size. The snap applications run in sandbox and they can be installed directly from Ubuntu Software.

Eclipse snap

1. So you can just open Ubuntu Software, search for and install Eclipse 4.7.3a snap package:

1. There are 2 Eclipse packages in Ubuntu Software. Check package details for version and source.

2. You see the alert “The application is unconfined. It can …”. That’s because the snap is installed in --classic mode so the IDE can access user directories.

3. Ubuntu 16.04 users who never installed a snap may need to install snapd first via command:

sudo apt-get install snapd snapd-xdg-open

For those prefer Linux command, run command in terminal to install the Eclipse snap:

snap install --classic eclipse

2. Eclipse needs java. If you don’t have it, run command in terminal to install OpenJDK java environment:

sudo apt-get install default-jre

You can also install Oracle Java 8 and/or 10 via this tutorial.

sudo apt-get install oracle-java10-installer

Once installed, Oracle Java 10 should be automatically set as default. If not, run command:

sudo apt-get install oracle-java10-set-default

3. Finally check your java version via java -version and javac -version:

Install Oracle Java JDK 8 in Ubuntu 18.04:

Webupd8 Team maintains a PPA repository that contains Oracle Java 8 installer scripts for all current Ubuntu releases.

1. Open terminal and run command to add the PPA:

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get install oracle-java8-set-default

Uninstall:

It’s always easy to remove the PPA packages, simply open terminal and run command:

sudo apt-get remove --autoremove oracle-java8-installer oracle-java10-installer
