Install Eclipse by installer package on Ubuntu 20.04

06 Nov 2020

Eclipse is widely used for Java Developers. You can install other IDE for Eclipse too. I don't want to use snap install eclipse but want to install from its installer.

Requirements

  • Require Java
1
sudo apt install openjdk-11-jdk-headless

To install it, I followed this instruction:

https://askubuntu.com/questions/695382/how-to-install-eclipse-using-its-installer

  • I run with sudo ./eclipse-inst and use and use /opt as installation path.
  • Do not use /root/java-2020-09 this will cause many troubles later.

We need to create a desktop file.

sudo nano /usr/share/applications/eclipse.desktop

Remember to update the desktop file accordingly to your version. Here is mine:

You can easily fix it with this one:
