Ant is the predominant build environment for Java projects. Groovy is a leading Scripting language for the JVM. The good news is that you can use them together easily and with many benefits.
Existing Ant Users (Java Projects): If you are already familiar with using Ant with a traditional
build.xml file, then you can continue to do so with almost no changes. If you want you can begin to use the
<groovy> Ant task to bring the full power of a scripting language to your build scripts.
Existing Ant Users (Groovy or mixed Groovy/Java Projects): If you wish to pre-compile your Groovy scripts as part of your build process (it can help catch syntactic errors earlier if you do) then you need to know about the
<groovyc> Ant task. You will find it almost identical to the
javac task which you are probably already familiar with.
Existing Groovy Users: You probably want to consider how you can use AntBuilder to leverage the many available Ant tasks directly in your code using a DSL-style notation. You can leverage Ant Libraries in the same way.
