REVERT TO CONSOLE

Problem: You want to use groovy all the time, but ignorant (but paying) forces keep you writing verbose tedious Java code instead.

Solution: Use groovy instead of shell scripts! In large Java development projects, developing in a local environment comes with a maddening list of pulling levers, pushing buttons, and spinning wheels. Many of these can be automated with scripts, and those that can can be Groovy scripts.

I wrote this script to clean up after liferay portal kruft:

#!/usr/bin/env groovy

class Build{
    def ant = new AntBuilder()
    def localhostDir = "C:/dev/liferay/tomcat/work/Catalina/localhost"
    def portraitDir = localhostDir + "/portrait"
    def liferayDir = "C:/Documents and Settings/ujxh744/liferay"
    def luceneDir = liferayDir + "/lucene"
    def classpath = ant.path {
        dirset(dir: liferayDir){
            include(name: "*")
        }
        dirset(dir: localhostDir) {
            include(name: "*")
        }
   }

    void cleanUpLiferayShit() {
        ant.delete(dir: portraitDir)
        ant.delete(dir: luceneDir)
    }

    void echoDirectories(dirPath) {
        def pathList = dirPath.list()
        println "There are " + dirPath.size() + " remaining directories"
        dirPath.list().each{ arg ->
            println arg
        }
    }
}

def b = new Build()
b.cleanUpLiferayShit()
b.echoDirectories( b.getClasspath())
