Programming Groovy 2

10.2 Running Groovy

We have two options for running Groovy code. First, we can use the ​groovy​ command on our source code. Then Groovy automatically compiles code in memory and executes it. We don’t have to take an explicit step to compile it.

Second, if we want to take a more traditional Javalike approach of explicitly compiling code to create bytecode—the ​.class​ file—we can do that using the ​groovyc​ compiler. To execute the bytecode, we’ll use the ​java​ command just like we would to execute our compiled Java code. The only difference is that we need to have the ​groovy-all-2.1.0.jar​ file in the ​classpath​. Remember to add a dot (​.​) to the ​classpath​ so ​java​ can find your classes in the current directory. This Java archive (JAR) ...
