Interface ConfigurationContainer

All Superinterfaces:

Collection<Configuration>, org.gradle.util.Configurable<NamedDomainObjectContainer<Configuration>>, DomainObjectCollection<Configuration>, Iterable<Configuration>, NamedDomainObjectCollection<Configuration>, NamedDomainObjectContainer<Configuration>, NamedDomainObjectSet<Configuration>, Set<Configuration>

public interface ConfigurationContainer
extends NamedDomainObjectContainer<Configuration>

A ConfigurationContainer is responsible for declaring and managing configurations. See also Configuration.

You can obtain a ConfigurationContainer instance by calling Project.getConfigurations(), or using the configurations property in your build script.

The configurations in a container are accessible as read-only properties of the container, using the name of the configuration as the property name. For example:

 configurations.add('myConfiguration')
 configurations.myConfiguration.transitive = false
 

A dynamic method is added for each configuration which takes a configuration closure. This is equivalent to calling getByName(String, groovy.lang.Closure). For example:

 configurations.add('myConfiguration')
 configurations.myConfiguration {
     transitive = false
 }
 

Examples

An example showing how to refer to a given configuration by name in order to get hold of all dependencies (e.g. jars, but only)

   apply plugin: 'java' //so that I can use 'compile' configuration

   //copying all dependencies attached to 'compile' into a specific folder
   task copyAllDependencies(type: Copy) {
     //referring to the 'compile' configuration
     from configurations.compile
     into 'allLibs'
   }
 

An example showing how to declare and configure configurations

 apply plugin: 'java' //so that I can use 'compile', 'testCompile' configurations

 configurations {
   //adding a configuration:
   myConfiguration

   //adding a configuration that extends existing configuration:
   //(testCompile was added by the java plugin)
   myIntegrationTestsCompile.extendsFrom(testCompile)

   //configuring existing configurations not to put transitive dependencies on the compile classpath
   //this way you can avoid issues with implicit dependencies to transitive libraries
   compile.transitive = false
   testCompile.transitive = false
 }

Method Detail

getByName

Configuration getByName(String name)
                        throws UnknownConfigurationException

Locates an object by name, failing if there is no such object.

Specified by:

getByName in interface NamedDomainObjectCollection<Configuration>

Parameters:

name - The object name

Returns:

The object with the given name. Never returns null.

Throws:

UnknownConfigurationException

getAt

Configuration getAt(String name)
                    throws UnknownConfigurationException

Locates an object by name, failing if there is no such task. This method is identical to NamedDomainObjectCollection.getByName(String). You can call this method in your build script by using the groovy [] operator.

Specified by:

getAt in interface NamedDomainObjectCollection<Configuration>

Parameters:

name - The object name

Returns:

The object with the given name. Never returns null.

Throws:

UnknownConfigurationException

getByName

Configuration getByName(String name,
                        Closure configureClosure)
                        throws UnknownConfigurationException

Locates an object by name, failing if there is no such object. The given configure closure is executed against the object before it is returned from this method. The object is passed to the closure as it's delegate.

Specified by:

getByName in interface NamedDomainObjectCollection<Configuration>

Parameters:

name - The object name

configureClosure - The closure to use to configure the object.

Returns:

The object with the given name, after the configure closure has been applied to it. Never returns null.

Throws:

UnknownConfigurationException

add

Configuration add(String name)
                  throws InvalidUserDataException

Adds a configuration with the given name.

Parameters:

name - The name of the new configuration.

Returns:

The newly added configuration.

Throws:

InvalidUserDataException - when a configuration with the given name already exists in this container.

add

Configuration add(String name,
                  Closure configureClosure)
                  throws InvalidUserDataException

Adds a configuration with the given name. The given configuration closure is executed against the configuration before it is returned from this method.

Parameters:

name - The name of the new configuration.

configureClosure - The closure to use to configure the configuration.

Returns:

The newly added configuration.

Throws:

InvalidUserDataException - when a configuration with the given name already exists in this container.

detachedConfiguration

Configuration detachedConfiguration(Dependency... dependencies)

Creates a configuration, but does not add it to this container.

Parameters:

dependencies - The dependencies of the configuration.

Returns:

The configuration.
