  - ### getCredentials

    PasswordCredentials getCredentials()
    Returns the username and password credentials used to authenticate to this repository.

    Returns:
      the credentials
    Throws:
      `IllegalStateException` - if the credential type was previously set with `credentials(Class, Action)` where the type was not `PasswordCredentials`

  - ### credentials

    <T extends Credentials> void credentials(Class<T> credentialsType, Action<? super T> action)
    Configures the credentials for this repository using the supplied action.

    If no credentials have been assigned to this repository, an empty set of credentials of the specified type will be assigned to this repository and given to the configuration action. If credentials have already been specified for this repository, they will be passed to the given configuration action.

        repositories {
            maven {
                url = "https://example.com/aws/proxy"
                credentials(AwsCredentials) {

  - ### credentials

    void credentials(Class<? extends Credentials> credentialsType)
    Configures the credentials for this repository that will be provided by the build.

    Credentials will be provided from Gradle properties based on the repository name. If credentials for this repository can not be resolved and the repository will be used in the current build, then the build will fail to start and point to the missing configuration.

        repositories {
            maven {
                url = "https://example.com/m2"
                credentials(PasswordCredentials)

  - ### authentication

    void authentication(Action<? super AuthenticationContainer> action)

    Configures the authentication schemes for this repository.

    This method executes the given action against the `AuthenticationContainer` for this project. The `AuthenticationContainer` is passed to the closure as the closure's delegate.

    If no authentication schemes have been assigned to this repository, a default set of authentication schemes are used based on the repository's transport scheme.

        repositories {
            maven {
                url = "https://example.com/m2"
                authentication {
                    basic(BasicAuthentication)
                }
            }
        }

    Supported authentication scheme types extend `Authentication`.

    Parameters:
      `action` - the action to use to configure the authentication schemes.
