Compatibility with Contiki 3.0

[ycwuaa]

Thank you for your help :)

[dhondta]

I fixed a bug the make command. Normally, a simulation/campaign can be made without error. run is not tested yet.

Note that I added an ´update´ command to make it easier to either update Contiki-OS as well as RPL Attacks Framework.

Test Environment:

• Ubuntu 14.04 LTS
• Contiki-3.x-2370
• OpenJDK 7

Status: successful

Cooja seems to fail because of a plugin, meaning that the simulations crash very early before making the expected results, thus resulting in an error in the parser.

I must still investigate to fix this compatibility issue.

Diagnostic: Neither Contiki-OS nor RPL Attacks Framework is the problem ; it seems that Rhino Javascript Engine was replaced by Nashorn JavaScript Engine in Java 8 and that importPackage (present in simulations' script.js) is not supported anymore and throws an error at Cooja's startup.

Solution: See templates/experiment/script.js, this line was added at the beginning for Rhino code support (still works with previous JDK versions) :

try { load("nashorn:mozilla_compat.js"); } catch(e) {}

• Using Rhino JSR-223 engine with JDK8

Cooja error is now handled in run command (see commit e77dc5f) ;
