Turning now to the
_GrailsClean
script, let me highlight a couple of small sections
from it:
includeTargets << grailsScript("_GrailsEvents")
target (cleanAll: "Cleans a Grails project") {
clean()
cleanTestReports()
grailsConsole.updateStatus "Application cleaned."
}
target (clean: "Implementation of clean") {
depends(cleanCompiledSources, cleanWarFile)
}
Theresemblance toAntisnotaccidental. Gantscriptscontaintargets,andtargetscanbein-
vokedasthoughtheyweremethodcalls. Herethetargetdefinedwiththename
cleanAll
invokes two other tasks (
clean
and
cleanTestReports
) and then invokes the
up-
dateStatus
method on the predefined
grailsConsole
object.
The
clean
task uses the
depends
method (again analogous to the same functionality
in Ant) to make sure that the
cleanCompiledSources
and
cleanWarFile
tasks
are invoked when the
clean
task is invoked. Here's a snippet from the
cleanCom-
piledSources
task:
target (cleanCompiledSources: "Cleans compiled Java and Groovy sources") {
def webInf = "${basedir}/web-app/WEB-INF"
ant.delete(dir:"${webInf}/classes")
ant.delete(file:webXmlFile.absolutePath, failonerror:false)
ant.delete(dir:"${projectWorkDir}/gspcompile", failonerror:false)
Thetaskgoesontodeletemanymoreitems,delegatingtoaninternal
AntBuilder
object
in each case. The
cleanWarFile
task shows how you can mix in Groovy logic code in-
side a script:
target (cleanWarFile: "Cleans the deployable .war file") {
if (buildConfig.grails.project.war.file) {
warName = buildConfig.grails.project.war.file
}
else {
def fileName = grailsAppName
def version = metadata.'app.version'
if (version) {
fileName += "-$version"
