Error when building from source

[nicjohnston]

I just cloned this repository and when I went to build it using the instructions from the readme, the following error was produced:

~/ESP8266_2/Arduino/build$ ant dist

Total time: 4 seconds

I tried the ant dist command with version numbers 1.6.5 and 1.6.4 and got the same result.
There is probably a simple solution, but I am missing it.
Thanks,

You need to install JDK 8, apparently you have Java 7:

javac: invalid target release: 1.8
