ARV Toolchain on Eclipse not showing


I'm not sure if this is the correct sub-forum for my question, but here goes:

I'm following this guide: Arduino Playground - Eclipse on getting Eclipse C++ compiling for Arduino on Ubuntu working.

I've run the command:

sudo apt-get install avrdude binutils-avr gcc-avr avr-libc gdb-avr

It didn't show any errors while installing.

I've also followed the instructions on this page: Plugin Download - AVR-Eclipse to install the ARV keychain from the "Install new software" section on Eclipse, and have restarted Eclipse. When trying to install this plugin again, Eclipse reports that it is already installed.

When I try to create a new project I don't see any ARV keychains listed. I also don't see ARV in Window > Preferences in Eclipse.

I also found this guide:,62094.0.html, but it has not helped solve this problem.

I'm not too familiar with how Eclipse is detecting if this software is installed or not, so am wondering if anyone can provide assistance to help fix this.

The problem was Java's installation. I had to remove the JDK and Eclipse's config file (rm -r ~/.eclipse/) before it would be detected. This took too long to figure out, so I hope it helps someone else in the future. If you're having problems with Eclipse, always check what Java is doing (Even if you're using C++). It won't always show an error.
