# MavenArtifactRepository

API Documentation: | `MavenArtifactRepository`

An artifact repository which uses a Maven format to store artifacts and meta-data.

Repositories of this type are created by the `RepositoryHandler.maven(org.gradle.api.Action)` group of methods.

### Properties

Property | Description
`allowInsecureContinueWhenDisabled` | Specifies whether to continue checking other repositories if this repository is disabled due to connection or communication errors.
`allowInsecureProtocol` | Specifies whether it is acceptable to communicate with a repository over an insecure HTTP connection.
`artifactUrls` | Deprecated The additional URLs to use to find artifact files. Note that these URLs are not used to find POM files.
`authentication` | The authentication schemes for this repository.
`credentials` | The credentials of the specified type used to authenticate with this repository.
`name` | The name for this repository. A name must be unique amongst a repository set. A default name is provided for the repository if none is provided.
`url` | The base URL of this repository. This URL is used to find both POMs and artifact files.

### Methods

Method | Description
`artifactUrls(urls)` | Deprecated Adds some additional URLs to use to find artifact files. Note that these URLs are not used to find POM files.
`authentication(action)` | Configures the authentication schemes for this repository.
`credentials(credentialsType)` | Configures the credentials for this repository that will be provided by the build.
`credentials(credentialsType, action)` | Configures the credentials for this repository using the supplied action.
`credentials(action)` | Configures the username and password credentials for this repository using the supplied action.
`metadataSources(configureAction)` | Configures the metadata sources for this repository. This method will replace any previously configured sources of metadata.

### Property details

#### ``Property`<`Boolean`>` `allowInsecureContinueWhenDisabled`

Specifies whether to continue checking other repositories if this repository is disabled due to connection or communication errors.

The conventional value for this property is `false`, which means to not continue to check other repositories after this one.

#### `boolean` `allowInsecureProtocol`

Specifies whether it is acceptable to communicate with a repository over an insecure HTTP connection.

For security purposes this intentionally requires a user to opt-in to using insecure protocols on case by case basis.

Gradle intentionally does not offer a global system/gradle property that allows a universal disable of this check.

Allowing communication over insecure protocols allows for a man-in-the-middle to impersonate the intended server, and gives an attacker the ability to serve malicious executable code onto the system.

#### ``Set`<`URI`>` `artifactUrls`

Note: This property is deprecated and will be removed in the next major version of Gradle.

The additional URLs to use to find artifact files. Note that these URLs are not used to find POM files.

#### `AuthenticationContainer` `authentication` (read-only)

The authentication schemes for this repository.

#### `T` `credentials` (read-only)

The credentials of the specified type used to authenticate with this repository.

If no credentials have been assigned to this repository, an empty set of credentials of the specified type is assigned to this repository and returned.

#### `String` `name`

The name for this repository. A name must be unique amongst a repository set. A default name is provided for the repository if none is provided.

The name is used in logging output and error reporting to point to information related to this repository.

#### `URI` `url`

The base URL of this repository. This URL is used to find both POMs and artifact files.

### Method details

#### `void` `artifactUrls`(``Object`...` urls)

Note: This method is deprecated and will be removed in the next major version of Gradle.

Adds some additional URLs to use to find artifact files. Note that these URLs are not used to find POM files.

The provided values are evaluated as per `Project.uri(java.lang.Object)`. This means, for example, you can pass in a `File` object, or a relative path to be evaluated relative to the project directory.

#### `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`.

#### `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)
        }
    }

The following credential types are currently supported for the `credentialsType` argument:

- `PasswordCredentials`
- `AwsCredentials`
- `HttpHeaderCredentials`

#### `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) {
                accessKey = "myAccessKey"
                secretKey = "mySecret"
            }
        }
    }

The following credential types are currently supported for the `credentialsType` argument:

- `PasswordCredentials`
- `AwsCredentials`

#### `void` `credentials`(``Action`<? super `PasswordCredentials`>` action)

Configures the username and password credentials for this repository using the supplied action.

If no credentials have been assigned to this repository, an empty set of username and password credentials is assigned to this repository and passed to the action.

    repositories {
        maven {
            url = "https://example.com/m2"
            credentials {
                username = 'joe'
                password = 'secret'
            }
        }
    }

#### `void` `metadataSources`(``Action`<? super `MetadataSources`>` configureAction)

Configures the metadata sources for this repository. This method will replace any previously configured sources of metadata.
