About this Book

You don't desire the complete strength of Java whilst you're writing a construct script, an easy approach application, or a light-weight net app—but that's the place Groovy shines brightest. This dependent JVM-based dynamic language extends and simplifies Java so that you can pay attention to the duty handy rather than handling minute information and pointless complexity.

Its syntax shares much in common with C and C++. Language constructs that caused intermediatelevel developers problems, like memory management and pointer arithmetic, were handled automatically or removed from programmer control altogether. The language was small (as hard as that might be to imagine now), easy to write, and, above Issues with Java 5 all, free. Just download a JDK, access the library docs (making available clean, up-todate, hyperlinked library documentation was quite the innovation at the time), and start coding.

0" } Dependencies in Maven form Now running gradle build results in a series of stages: :compileJava :processResources :classes :jar :assemble :compileTestJava :processTestResources :testClasses :test :check :build The result is a nice, hyperlinked set of documentation of all the test cases, plus a JAR file for deployment. Of course, if there’s a plugin called java, there’s a plugin called groovy. Better yet, the Groovy plugin includes the Java plugin and, as usual, augments and improves it. If your project is similar to the ones discussed in this book, in that it combines Groovy and Java classes and uses each where most helpful, then all you need is the Groovy plugin and you’re ready to go.
