How to run groovy script in java?

Question

I have a groovy script and i want to execute it in java. Could someone provide me with further documentation / examples on how this is possible?

Answer 1

Basic Java+Groovy Integration:

// call groovy expressions from Java code
Binding binding = new Binding();
binding.setVariable("foo", new Integer(2));
GroovyShell shell = new GroovyShell(binding);

Object value = shell.evaluate(groovyScript);

See this article for more ways to call Groovy from Java

PS: You need to include groovy-all-m.n.m.jar e.g. groovy-all-2.1.6.jar in your Java program, for example:

  org.codehaus.groovy
  groovy-all
  2.4.8
