How to delete an empty directory (or the directory with all contents recursively) in gradle?

Question

I can\'t figure out how to delete all contents of a directory.

For cleaning out a directory, I want to remove all files and directories inside it: I want to wipe ev

Answer 1

Following will delete all content from the src folder but leaves the folder itself untouched:

task deleteGraphicsAssets(type: Delete) {
    def dirName = "src" 
    file( dirName ).list().each{
        f -> 
            delete "${dirName}/${f}"
    }
}

Answer 2

To delete the src directory and all its contents:

task deleteGraphicsAssets(type: Delete) {
    delete "src"
}

Answer 3

Groovy enhances the File class with several methods. You can delete a directory with all it's subdirectories and files using deleteDir() method.

task deletebin << {
    def binDir = new File('bin')
    binDir.deleteDir()
}

Answer 4

clean {
    delete += fileTree('src').include('**/*')
}

This 'clean' task's configuration seems to work.

Answer 5

Found using FileTree#visit worked.

ConfigurableFileTree ft = fileTree('someDir')
ft.include("xxx")
ft.exclude("yyy")

task delteFilesOnly() {
    doLast {
        //// for test
        //ft.each { File file ->
        //    println "===== " + file.absolutePath
        //}
        delete ft
    }
}

task deleteFilesAndDirs(){
    doLast {
        ft.visit { FileVisitDetails fvd ->
            //// for test
            //println "----- " + file.absolutePath
            delete fvd.file
        }
    }
}

Answer 6

At the risk of resurrecting an answered topic, there's a relatively easy way to do this.

This task will delete all files and directories under 'src' without traversing the file tree and without removing to 'src' dir

task deleteGraphicsAssets(type:Delete) {
    delete file('src').listFiles()
}
