HelloWorld Error with Starter Package

Hi,
I’m new to URCaps.
Am trying to build the HelloWorld project in the starter package of URSim 3.4.0.39 on VirtualBox.
I am getting this error:

I followed the instructions on the tutorial pdf, i have already maven 3.0.5 installed.
install.sh was not able to install the tool chain (amd and not 386), but i understand that is fine, so i re-ran it and chose No to install the tool chain.
What could be the issue? I did not see anyone with this error on the forums.
Thanks,
Omer

Found the issue. Here it is for future users.

This error:
CompilerMojo : Unsupported major.minor version 51.0
Led me to this post:

It seems that the Mojo plugin is incompatible with java 6. Updating to Java 8 solves the problem for me:

sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

Thank you for sharing your solution!
Please due note, that URCaps in PolyScope are based on Java 6.
So remember to check for compatibility, depending on how you have Java 8 as well on your system.

Thanks!
What other solution could i have found to the CompilerMojo : Unsupported major.minor version 51.0 error, which still use Java 6?
