OSX users can get it at openjdk-osx-build.

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.
