# Script

API Documentation: | `Script`

This interface is implemented by all Gradle scripts to add in some Gradle-specific methods. As your compiled script class will implement this interface, you can use the methods and properties declared by this interface directly in your script.

Generally, a `Script` object will have a delegate object attached to it. For example, a build script will have a `Project` instance attached to it, and an initialization script will have a `Gradle` instance attached to it. Any property reference or method call which is not found on this `Script` object is forwarded to the delegate object.

### Properties

Property | Description
`buildscript` | The script handler for this script. You can use this handler to manage the classpath used to compile and execute this script.
`logger` | The logger for this script. You can use this in your script to write log messages.
`logging` | The `LoggingManager` which can be used to control the logging level and standard output/error capture for this script. By default, System.out is redirected to the Gradle logging system at the QUIET log level, and System.err is redirected at the ERROR log level.

### Property details

#### `ScriptHandler` `buildscript` (read-only)

The script handler for this script. You can use this handler to manage the classpath used to compile and execute this script.

#### `Logger` `logger` (read-only)

The logger for this script. You can use this in your script to write log messages.

#### `LoggingManager` `logging` (read-only)

The `LoggingManager` which can be used to control the logging level and standard output/error capture for this script. By default, System.out is redirected to the Gradle logging system at the QUIET log level, and System.err is redirected at the ERROR log level.

### Script blocks

Block | Description
`buildscript` | Configures the classpath for this script.

### Script block details

#### `buildscript` { }

Configures the classpath for this script.

The given closure is executed against this script's `ScriptHandler`. The `ScriptHandler` is passed to the closure as the closure's delegate.

Delegates to:
  `ScriptHandler` from `buildscript`

### Methods

Method | Description
`apply(closure)` | Configures the delegate object for this script using plugins or scripts.
`apply(options)` | Configures the delegate object for this script using plugins or scripts.
`copy(closure)` | Copy the specified files. The given closure is used to configure a `CopySpec`, which is then used to copy the files. Example:
`copySpec(closure)` | Creates a `CopySpec` which can later be used to copy files or create an archive. The given closure is used to configure the `CopySpec` before it is returned by this method.
`delete(paths)` | Deletes files and directories.
`exec(closure)` | Executes an external command. The closure configures a `ExecSpec`.
`file(path)` | Resolves a file path relative to the directory containing this script. This works as described for `Project.file()`
`file(path, validation)` | Resolves a file path relative to the directory containing this script and validates it using the given scheme. See `PathValidation` for the list of possible validations.
`fileTree(closure)` | Creates a new `ConfigurableFileTree` using the provided closure. The closure will be used to configure the new file tree. The file tree is passed to the closure as its delegate. Example:
`fileTree(baseDir)` | Creates a new `ConfigurableFileTree` using the given base directory. The given baseDir path is evaluated as for `Script.file()`.
`fileTree(args)` | Creates a new `ConfigurableFileTree` using the provided map of arguments. The map will be applied as properties on the new file tree. Example:
`files(paths, configureClosure)` | Creates a new `ConfigurableFileCollection` using the given paths. The file collection is configured using the given closure. This method works as described for `Project.files()`. Relative paths are resolved relative to the directory containing this script.
`files(paths)` | Returns a `ConfigurableFileCollection` containing the given files. This works as described for `Project.files()`. Relative paths are resolved relative to the directory containing this script.
`javaexec(closure)` | Executes a Java main class. The closure configures a `JavaExecSpec`.
`mkdir(path)` | Creates a directory and returns a file pointing to it.
`relativePath(path)` | Returns the relative path from the directory containing this script to the given path. The given path object is (logically) resolved as described for `Script.file()`, from which a relative path is calculated.
`tarTree(tarPath)` | Creates a new `FileTree` which contains the contents of the given TAR file. The given tarPath path is evaluated as for `Script.file()`. You can combine this method with the `Script.copy()` method to untar a TAR file.
`uri(path)` | Resolves a file path to a URI, relative to the directory containing this script. Evaluates the provided path object as described for `Script.file()`, with the exception that any URI scheme is supported, not just 'file:' URIs.
`zipTree(zipPath)` | Creates a new `FileTree` which contains the contents of the given ZIP file. The given zipPath path is evaluated as for `Script.file()`. You can combine this method with the `Script.copy()` method to unzip a ZIP file.

### Method details

#### `void` `apply`(`Closure` closure)

Configures the delegate object for this script using plugins or scripts.

The given closure is used to configure an `ObjectConfigurationAction` which is then used to configure the delegate object.

#### `void` `apply`(``Map`<`String`, ?>` options)

Configures the delegate object for this script using plugins or scripts.

The following options are available:

- `from`: A script to apply to the delegate object. Accepts any path supported by `Script.uri()`.
- `plugin`: The id or implementation class of the plugin to apply to the delegate object.
- `to`: The target delegate object or objects.

For more detail, see `ObjectConfigurationAction`.

#### `WorkResult` `copy`(`Closure` closure)

Copy the specified files. The given closure is used to configure a `CopySpec`, which is then used to copy the files. Example:

    copy {
       from configurations.runtime
       into 'build/deploy/lib'
    }

Note that CopySpecs can be nested:

    copy {
       into 'build/webroot'
       exclude '**/.svn/**'
       from('src/main/webapp') {
          include '**/*.jsp'
          filter(ReplaceTokens, tokens:[copyright:'2009', version:'2.3.1'])
       }
       from('src/main/js') {
          include '**/*.js'
       }
    }

#### `CopySpec` `copySpec`(`Closure` closure)

Creates a `CopySpec` which can later be used to copy files or create an archive. The given closure is used to configure the `CopySpec` before it is returned by this method.

#### `boolean` `delete`(``Object`...` paths)

Deletes files and directories.

#### `ExecResult` `exec`(`Closure` closure)

Executes an external command. The closure configures a `ExecSpec`.

#### `File` `file`(`Object` path)

Resolves a file path relative to the directory containing this script. This works as described for `Project.file()`

#### `File` `file`(`Object` path, `PathValidation` validation)

Resolves a file path relative to the directory containing this script and validates it using the given scheme. See `PathValidation` for the list of possible validations.

#### `ConfigurableFileTree` `fileTree`(`Closure` closure)

    fileTree {
       from 'src'
       exclude '**/.svn/**'
    }.copy { into 'dest'}

The returned file tree is lazy, so that it scans for files only when the contents of the file tree are queried. The file tree is also live, so that it scans for files each time the contents of the file tree are queried.

#### `ConfigurableFileTree` `fileTree`(`Object` baseDir)

Creates a new `ConfigurableFileTree` using the given base directory. The given baseDir path is evaluated as for `Script.file()`.
