How to Install Eclipse CDT with Java 8¶
From Eclipse Neon, the minimal required version of Java becomes 8. Here is a note about how to configure the java environment properly to run the latest Eclipse in Ubuntu 14.04.
Download Eclipse CDT¶
Download eclipse from the [official website](https://eclipse.org/cdt/downloads.php). Extract it to your preferred location.
Install Java 8¶
Java 8 is not readily available in the apt-get repository of Ubuntu 14.04. You can use the following third-party ppa to install it.
$ sudo add-apt-repository ppa:openjdk-r/ppa
$ sudo apt-get update
$ sudo apt install openjdk-8-jdk
Configure the default Java Runtime¶
$ sudo update-alternatives --config java
Similarly, to choose a default javac compiler, run the following command. (You don’t need this step if you just want to run Eclipse CDT with no Java development.)
$ sudo update-alternatives --config javac
Now you should be able to run the latest Eclipse without the Java version error message.
