## [Groovy] Class FileTreeBuilder

- groovy.util.FileTreeBuilder

- A builder dedicated at generating a file directory structure from a specification. For example, imagine that you want to create the following tree:

       src/
        |--- main
        |     |--- groovy
        |            |--- Foo.groovy
        |--- test
              |--- groovy
                     |--- FooTest.groovy

  Then you can create the structure using:

           def tree = new FileTreeBuilder()
           tree.dir('src') {
              dir('main') {
                 dir('groovy') {
                    file('Foo.groovy', 'println "Hello"')
                 }
              }
              dir('test') {
                 dir('groovy') {
                    file('FooTest.groovy', 'class FooTest extends GroovyTestCase {}')
                 }
              }
           }

  or with this shorthand syntax:

           def tree = new FileTreeBuilder()
           tree.src {
              main {
                 groovy {
                    'Foo.groovy'('println "Hello"')
                 }
              }
              test {
                 groovy {
                    'FooTest.groovy'('class FooTest extends GroovyTestCase {}')
                 }
              }
           }

  - ### Method Detail

    - #### File call(@DelegatesTo(value = FileTreeBuilder, strategy = Closure.DELEGATE_FIRST) Closure spec)

    - #### File dir(String name)

      Creates a new empty directory

      Parameters:
        `name` - the name of the directory to create
      Returns:
        the created directory

    - #### File dir(String name, @DelegatesTo(value = FileTreeBuilder, strategy = Closure.DELEGATE_FIRST) Closure cl)

      Creates a new directory and allows to specify a subdirectory structure using the closure as a specification

      Parameters:
        `name` - name of the directory to be created
        `cl` - specification of the subdirectory structure
      Returns:
        the created directory

    - #### File file(String name, CharSequence contents)

      Creates a file with the specified name and the text contents using the system default encoding.

      Parameters:
        `name` - name of the file to be created
        `contents` - the contents of the file, written using the system default encoding
      Returns:
        the file being created

    - #### File file(String name, byte[] contents)

      Creates a file with the specified name and the specified binary contents

      Parameters:
        `name` - name of the file to be created
        `contents` - the contents of the file
      Returns:
        the file being created

    - #### File file(String name, File source)

      Creates a file with the specified name and the contents from the source file (copy).

      Parameters:
        `name` - name of the file to be created
        `contents` - the contents of the file
      Returns:
        the file being created

    - #### File file(String name, @DelegatesTo(value = File, strategy = Closure.DELEGATE_FIRST) Closure spec)

      Creates a new file in the current directory, whose contents is going to be generated in the closure. The delegate of the closure is the file being created.

      Parameters:
        `name` - name of the file to create
        `spec` - closure for generating the file contents
      Returns:
        the created file
