Build failure

[tigre-bleu]

Hello,

I tried building mxisd but without success on Ubuntu 14.04. Here is the output:

:compileGroovy (Thread[Daemon worker Thread 2,5,main]) started.

Seems like you don't have JDK 8 installed, but only 7 which is the default on Ubuntu 14.04

[tigre-bleu]

Exact. That was the problem. Thanks. I suggest that this requirement is added in the readme file.

[maxidorius]

It's already present, I should put a table of content maybe tho.
