There are various options for compiling Groovy code and then either running it or using the Java objects it creates in Java code. 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. 1.1. 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') If you don't want to explicitly compile groovy code to bytecode you can just embed groovy directly into your Java application. As well as Java 1.4 and the Groovy jar we also depend at runtime on the ASM library. |
