ConfigurationContainer

API Documentation:ConfigurationContainer

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

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

configurations.create('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)

plugins {
    id 'java' //so that I can use 'implementation', 'compileClasspath' configuration
}

dependencies {
    implementation 'org.slf4j:slf4j-api:1.7.26'
}

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

An example showing how to declare and configure configurations

plugins {
    id 'java' // so that I can use 'implementation', 'testImplementation' configurations
}

configurations {
  //adding a configuration:
  myConfiguration

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

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

Methods

MethodDescription
consumable(name)
Incubating

Registers a new ConsumableConfiguration with an immutable role. Consumable configurations are meant to act as a variant in the context of Dependency Management and Publishing.

consumable(name, action)
Incubating

Registers a ConsumableConfiguration via ConfigurationContainer.consumable(java.lang.String) and then configures it with the provided action.

create(name)

Creates a new item with the given name, adding it to this container.

create(name, configureClosure)

Creates a new item with the given name, adding it to this container, then configuring it with the given closure.

create(name, configureAction)

Creates a new item with the given name, adding it to this container, then configuring it with the given action.

dependencyScope(name)
Incubating

Registers a new DependencyScopeConfiguration with an immutable role. Dependency scope configurations collect dependencies, dependency constraints, and exclude rules to be used by both resolvable and consumable configurations.

dependencyScope(name, action)
Incubating

Registers a DependencyScopeConfiguration via ConfigurationContainer.dependencyScope(java.lang.String) and then configures it with the provided action.

detachedConfiguration(dependencies)

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

getAt(name)

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

getByName(name)

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

getByName(name, configureClosure)

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 its delegate.

getByName(name, configureAction)

Locates an object by name, failing if there is no such object. The given configure action is executed against the object before it is returned from this method.

maybeCreate(name)

Looks for an item with the given name, creating and adding it to this container if it does not exist.

named(name)

Locates a object by name, without triggering its creation or configuration, failing if there is no such object.

named(name, type)

Locates a object by name and type, without triggering its creation or configuration, failing if there is no such object.

named(name, type, configurationAction)

Locates a object by name and type, without triggering its creation or configuration, failing if there is no such object. The given configure action is executed against the object before it is returned from the provider.

named(name, configurationAction)

Locates a object by name, without triggering its creation or configuration, failing if there is no such object. The given configure action is executed against the object before it is returned from the provider.

named(nameFilter)
Incubating

Returns a collection containing the objects with names matching the provided filter. The returned collection is live, so that when matching objects are added to this collection, they are also visible in the filtered collection. This method will NOT cause any pending objects in this container to be realized.

register(name)

Defines a new object, which will be created when it is required. A object is 'required' when the object is located using query methods such as NamedDomainObjectCollection.getByName(java.lang.String) or when Provider.get() is called on the return value of this method.

register(name, configurationAction)

Defines a new object, which will be created and configured when it is required. An object is 'required' when the object is located using query methods such as NamedDomainObjectCollection.getByName(java.lang.String) or when Provider.get() is called on the return value of this method.

resolvable(name)
Incubating

Registers a ResolvableConfiguration with an immutable role. Resolvable configurations are meant to resolve dependency graphs and their artifacts.

resolvable(name, action)
Incubating

Registers a ResolvableConfiguration via ConfigurationContainer.resolvable(java.lang.String) and then configures it with the provided action.

Returns a collection containing the objects with names matching the provided filter. The returned collection is live, so that when matching objects are added to this collection, they are also visible in the filtered collection. This method will NOT cause any pending objects in this container to be realized.

Defines a new object, which will be created when it is required. A object is 'required' when the object is located using query methods such as NamedDomainObjectCollection.getByName(java.lang.String) or when Provider.get() is called on the return value of this method.

It is generally more efficient to use this method instead of NamedDomainObjectContainer.create(java.lang.String), as that method will eagerly create the object, regardless of whether that object is required for the current build or not. This method, on the other hand, will defer creation until required.

NamedDomainObjectProvider<T> register(String name, Action<? super T> configurationAction)

Defines a new object, which will be created and configured when it is required. An object is 'required' when the object is located using query methods such as NamedDomainObjectCollection.getByName(java.lang.String) or when Provider.get() is called on the return value of this method.

It is generally more efficient to use this method instead of NamedDomainObjectContainer.create(java.lang.String, org.gradle.api.Action) or NamedDomainObjectContainer.create(java.lang.String), as those methods will eagerly create and configure the object, regardless of whether that object is required for the current build or not. This method, on the other hand, will defer creation and configuration until required.
