Groovy - Compiling Groovy

There are various options for compiling Groovy code and then either running it or
using the Java objects it creates in Java code.

Compling Groovy code to bytecode using a script

There is an Ant task called groovyc which works pretty similarly to the javac Ant
task which takes a bunch of groovy source files and compiles them into Java bytecode. Each
groovy class then just becomes a normal Java class you can use inside your Java code if you wish.
Indeed the generated Java class is indistinguishable from a normal Java class, other than it
implements the GroovyObject interface.

Compiling Groovy code to bytecode using Ant

The groovyc Ant task is implemented by the Groovyc class.
You can see an example of this in action inside Groovy's maven.xml file (just search for 'groovyc')

Dynamically using Groovy inside Java applications

If you don't want to explicitly compile groovy code to bytecode you can just
embed groovy directly into your Java application.

Runtime dependencies

As well as Java 1.4 and the Groovy jar we also depend at runtime on the ASM library.
