OSX users can get it at java site.

Download and install it to your user(not to the entire machine) and before running mvn install run (or use Java7 as default compiler):

	export JAVA_HOME=$(/usr/libexec/java_home -v 1.7)

1. git clone https://github.com/dynjs/dynjs.git && cd dynjs
2. mvn install

Alternatively download the latest version from our CI job.

Run ./run-repl for the REPL and try the snippet below:

var x = 1 + 1;
print(x);

For more options, run java -jar target/dynjs-all.jar --help.
