Unzip Archive with Groovy

Question

is there a built-in support in Groovy to handle Zip files (the groovy way)?

Or do i have to use Java\'s java.util.zip.ZipFile to process Zip files in Groovy ?

Answer 1

Although taking the question a bit into another direction, I started off using Groovy for a DSL that I was building, but ended up using Gradle as a starting point to better handle a lot of the file-based tasks that I wanted to do (eg., unzip and untar files, execute other programs, etc). Gradle builds on what groovy can do, and can be extended further via plugins.

// build.gradle
task doUnTar << {
    copy {
        // tarTree uses file ext to guess compression, or may be specific
        from tarTree(resources.gzip('foo.tar.gz'))
        into getBuildDir()
    }
}

task doUnZip << {
    copy {
        from zipTree('bar.zip')
        into getBuildDir()
    }
}

Then, for example (this extracts the bar.zip and foo.tgz into the directory build):

$ gradle doUnZip
$ gradle doUnTar
