[Java] Interface Script

public interface 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.

Method Detail

apply

public 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.

Parameters:: closure - The closure to configure the ObjectConfigurationAction.

apply

public void apply(Map 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 uri(Object).
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.

Parameters:: options - The options to use to configure the ObjectConfigurationAction.

buildscript

public void buildscript(Closure configureClosure)

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.

Parameters:: configureClosure - the closure to use to configure the script classpath.

copy

public 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'
    }
 }

Parameters:: closure - Closure to configure the CopySpec

Returns:: WorkResult that can be used to check if the copy did any work.

copySpec

public 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.

Parameters:: closure - Closure to configure the CopySpec

Returns:: The CopySpec

delete

public boolean delete(Object... paths)

Deletes files and directories.

Parameters:: paths - Any type of object accepted by Project.files

Returns:: true if anything got deleted, false otherwise

exec

public ExecResult exec(Closure closure)

Executes an external command. The closure configures a ExecSpec.

Parameters:: closure - The closure for configuring the execution.

Returns:: the result of the execution

file

public File file(Object path)

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

Parameters:: path - The object to resolve as a File.

Returns:: The resolved file. Never returns null.

file

public 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.

throws:: InvalidUserDataException When the file does not meet the given validation constraint.

Parameters:: path - An object to resolve as a File.; validation - The validation to perform on the file.

Returns:: The resolved file. Never returns null.

fileTree

public ConfigurableFileTree fileTree(Object baseDir)

Creates a new ConfigurableFileTree using the given base directory. The given baseDir path is evaluated as per file(Object).

Note: to use a closure as the baseDir, you must explicitly cast the closure to Object to force the use of this method instead of fileTree(Closure). Example:

 fileTree((Object){ someDir })

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.

Parameters:: baseDir - The base directory of the file tree. Evaluated as per file(Object).

Returns:: the file tree. Never returns null.

fileTree

public ConfigurableFileTree fileTree(Map args)

Creates a new ConfigurableFileTree using the provided map of arguments. The map will be applied as properties on the new file tree. Example:

 fileTree(dir:'src', excludes:['**/ignore/**','**/.svn/**'])

Parameters:: args - map of property assignments to ConfigurableFileTree object

Returns:: the configured file tree. Never returns null.

fileTree

public ConfigurableFileTree fileTree(Closure 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 {
    from 'src'
    exclude '**/.svn/**'
 }.copy { into 'dest'}

deprecated:: Use fileTree(Object,Closure) instead.

Parameters:: closure - Closure to configure the ConfigurableFileTree object

Returns:: the configured file tree. Never returns null.

fileTree

public ConfigurableFileTree fileTree(Object baseDir, Closure configureClosure)

Creates a new ConfigurableFileTree using the given base directory. The given baseDir path is evaluated as per file(Object). The closure will be used to configure the new file tree. The file tree is passed to the closure as its delegate. Example:

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

Parameters:: baseDir - The base directory of the file tree. Evaluated as per file(Object).; configureClosure - Closure to configure the ConfigurableFileTree object.

Returns:: the configured file tree. Never returns null.

files

public ConfigurableFileCollection files(Object... 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.

Parameters:: paths - The paths to the files. May be empty.

Returns:: The file collection. Never returns null.

files

public ConfigurableFileCollection files(Object paths, Closure 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.

Parameters:: paths - The contents of the file collection. Evaluated as per files(Object...).; configureClosure - The closure to use to configure the file collection.

Returns:: the configured file tree. Never returns null.

getBuildscript

Returns:: The logger. Never returns null.

getLogging

public LoggingManager getLogging()

Returns 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.

Returns:: the LoggingManager. Never returns null.

getResources

public ResourceHandler getResources()

Provides access to resource-specific utility methods, for example factory methods that create various resources.

Returns:: Returned instance contains various resource-specific utility methods.

javaexec

public ExecResult javaexec(Closure closure)

Executes a Java main class. The closure configures a JavaExecSpec.

Parameters:: closure - The closure for configuring the execution.

Returns:: the result of the execution

mkdir

public File mkdir(Object path)

Creates a directory and returns a file pointing to it.

throws:: org.gradle.api.InvalidUserDataException If the path points to an existing file.

Parameters:: path - The path for the directory to be created. Evaluated as per file(Object).

Returns:: the created directory

relativePath

public String relativePath(Object 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 file(Object), from which a relative path is calculated.

Parameters:: path - The path to convert to a relative path.

Returns:: The relative path. Never returns null.

tarTree

public FileTree tarTree(Object tarPath)

Creates a new FileTree which contains the contents of the given TAR file. The given tarPath path can be:

an instance of Resource
any other object is evaluated as per file(Object)

Unless custom implementation of resources is passed, the tar tree attempts to guess the compression based on the file extension.

You can combine this method with the copy(groovy.lang.Closure) method to untar a TAR file:

 task untar(type: Copy) {
   from tarTree('someCompressedTar.gzip')

   //tar tree attempts to guess the compression based on the file extension
   //however if you must specify the compression explicitly you can:
   from tarTree(resources.gzip('someTar.ext'))

   //in case you work with unconventionally compressed tars
   //you can provide your own implementation of a ReadableResource:
   //from tarTree(yourOwnResource as ReadableResource)

   into 'dest'
 }

Parameters:: tarPath - The TAR file or an instance of Resource.

Returns:: the file tree. Never returns null.

uri

public URI uri(Object path)

Resolves a file path to a URI, relative to the directory containing this script. Evaluates the provided path object as described for file(Object), with the exception that any URI scheme is supported, not just 'file:' URIs.

Parameters:: path - The object to resolve as a URI.

Returns:: The resolved URI. Never returns null.

zipTree

public FileTree zipTree(Object zipPath)

Creates a new FileTree which contains the contents of the given ZIP file. The given zipPath path is evaluated as per file(Object). You can combine this method with the copy(groovy.lang.Closure) method to unzip a ZIP file.
