# ConfigurationContainer

@ServiceScope(value = Project::class)
interface ConfigurationContainer : NamedDomainObjectContainer<T> (source)

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

You can obtain a `ConfigurationContainer` instance by calling 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

Content copied to clipboard

A dynamic method is added for each configuration which takes a configuration closure. This is equivalent to calling getByName. 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
    }
