Nebula Core

This specific project holds some "helper" classes for testing and interacting with Gradle. It's not meant to get too big, but should serve as a central place for all plugins. This project should have no dependency and not contain any specific plugins.

Tasks

Download

A task to download a file, with incremental processing support. Current implementation is naive, but it'll be improved later. Either downloadBase and downloadFileName can be specified or a full URI as downloadUrl. The destinationDir can be specified but it's optional, though it can always be used by other tasks to reference its output.

import nebula.core.tasks.Download

task download(type: Download) {
    downloadBase = 'http://localhost'
    downloadFileName = 'file.zip'
}

task downloadFull(type: Download) {
    downloadUrl = 'http://localhost/file.zip'
}

Unzip

While unzipping comes built-in to Gradle, via ZipTree, encapsulating a few things in a task does make it easier.

import nebula.core.tasks.Unzip

task unzip(type: Unzip) {
    from(file('tmp/resources.zip'))
}

It is essentially still a Copy task, but with the added advantage of a from method to allow pulling from the output of another task. And a convenience method, firstDirectory, to return the first directory in the zip file, which is common.

import nebula.core.tasks.*

task download(type: Download) {
    downloadBase = 'http://www.us.apache.org/dist/tomcat/tomcat-6/v6.0.39/bin'
    downloadFileName = 'apache-tomcat-6.0.39.tar.gz'
}

task unzip(type: Unzip) {
    from(tasks.download)
}

task package(type: Deb) {
    into('/opt/tomcat6')
    from(tasks.unzip.firstDirectory()) // to get the apache-tomcat-6.0.39 directory out of the way
}

Untar

Task that works identically yo Unzip, but works against tar files.
