defining a task based on another pre-configured task

[Robert Fletcher]

Hi

I'm doing several very similar Exec tasks which only vary based on their
`workingDir`. The `commandLine` is the same in each case and incremental
build inputs & outputs are a function of the `workingDir`. Instead of
repeating myself is there a way I can define a new task as a pre-configured
Exec task?

Sorry if that's confusing. The build I'm talking about is here:

How 'bout:

['standard', 'nonStandard', 'customDir'].each { target ->
task("init${target.capitalize()}DirProject", type: Exec) {
workingDir "src/test/resources/projects/${target}"
commandLine 'bower', 'install'
inputs.files new File(workingDir, 'component.json')
outputs.files new File(workingDir, 'web-app')
}
}

Another option is to not subclass Exec, but use project.exec {} in your own implementation.

We are aware that this kind of composition can be awkward and have some long term plans to improve the situation.

You should be able to do something like this as well if you prefer:

def configureExec = { task, projectName, outputDir, cmdLine = ['bower,
install'] ->
task.workingDir "src/test/resources/projects/$projectName"
task.commandLine cmdLine
task.inputs.files file("${task.workingDir}/component.json")
task.outputs.files file("${task.workingDir}/$outputDir")
}

task initStandardProject(type: Exec){ task ->
configureExec(task, 'standard', 'components')
}

task initCustomDirProject(type: Exec){ task ->
configureExec(task, 'customDir', 'web-app')
}

task initNonStandardProject(type: Exec){ task ->
configureExec(task, 'nonStandard', 'lib', ['bower', 'install',
'--directory=lib'])
}

processTestResources.dependsOn initStandardProject
processTestResources.dependsOn initNonStandardProject
processTestResources.dependsOn initCustomDirProject

Thanks for the help, guys. I have a solution in place now based on Justin's
suggestion.
