As a Maven repository, Artifactory is both a source for artifacts needed for a build, and a target to deploy artifacts generated in the build process. Maven is configured using a settings.xml file located under your Maven home directory (typically, this will be /user.home/.m2/settings.xml). For more information on configuring Maven please refer to the
Apache Maven Project Settings Reference.
The default values in this file configure Maven to work with a default set of repositories used to resolve artifacts and a default set of plugins.
To work with Artifactory you need to configure Maven to perform the following two steps:
Once your Maven build is configured, Artifactory also provides tight integration with commonly used CI servers (such as Jenkins, TeamCity or a Bamboo) through a set of plugins that you can freely install and use.
If you select a Maven metadata file (maven-metadata.xml) or a POM file (pom.xml) in the Tree Browser, Artifactory provides corresponding tabs allowing you to view details on the selected item.

Resolving Artifacts through Artifactory
To configure Maven to resolve artifacts through Artifactory you need to modify the settings.xml. You can generate one automatically, or modify it manually.
Automatically Generating Settings
To make it easy for you to configure Maven to work with Artifactory, Artifactory can automatically generate a settings.xmlfile which you can save under your Maven home directory.
The definitions in the generated settings.xml file override the default central and snapshot repositories of Maven.
In the Artifact Repository Browser of the Artifacts module, select Set Me Up. In the Set Me Up dialog, set Maven in the Tool field and click "Generate Maven Settings". You can now specify the repositories you want to configure for Maven.
The repository from which to resolve releases
The repository from which to resolve snapshots
The repository from which to resolve plugin releases
The repository from which to resolve plugin snapshots
When set, you can select a repository that should mirror any other repository. For more details please refer to Additional Mirror Any Setup
Once you have configured the settings for Maven you can click "Generate Settings" to generate and save the settings.xml file.
Provisioning Dynamic Settings for Users
You can deploy and provision a dynamic settings template for your users.
Once downloaded, settings are generated according to your own logic and can automatically include user authentication information.
You can configure Maven to run with the Default Global Repository so that any request for an artifact will go through Artifactory which will search through all of the local and remote repositories defined in the system.
We recommend that you fine tune Artifactory to search through a more specific set of repositories by defining a dedicated virtual (or local) repository, and configure Maven to use that to resolve artifacts instead.
Additional Mirror Any Setup
In addition to overriding built-in Maven repositories, you can use the Mirror Any setting to redirect all requests to a Maven repository through Artifactory, including those defined inside POMs of plug-ins and third party dependencies. (While it does not adhere to best practices, it is not uncommon for POMs to reference Maven repositories directly). This ensures no unexpected requests directly to Maven are introduced by such POMs.
You can either check Mirror Any in the Maven Settings screen when generating your settings.xml file, or you can manually insert the following:
While this is a convenient way to ensure Maven only accesses repositories through Artifactory, it defines a coarse proxying rule that does not differentiate between releases and snapshots and relies on the single specified repository to do this resolution.
Artifactory encrypts passwords for safe and secure access to Maven repositories
To avoid having to use cleartext passwords, Artifactory encrypts the password in the settings.xml file that is generated. For example, in the above sample snippet we can see that the admin user name is specified in cleartext, but the password is encrypted:
Synchronizing authentication details for repositories with the same URL
If you have repository definitions (either for deployment or download) that use the same URL, Maven takes the authentication details (from the corresponding server definition) of the first repository encountered and uses it for the life-time of the running build for all repositories with the same URL. This may cause authentication to fail (producing 401 errors for downloads or deployment) if you are using different authentication details for the respective repositories. This is inherent Maven behavior and can only be solved by using the same authentication details for all repository definitions with the same URL in your settings.xml.
Forcing Authentication on Virtual Maven Repositories
Artifactory supports Maven repositories with Allow Anonymous Access enabled by default and will not query the Maven client for authentication parameters. If you want to enforce authentication you need to explicitly instruct Artifactory to request authentication parameters.
In the New or Edit Repository dialog of the Maven virtual repositories, select the Force Authentication check box.
When ‘Force Authentication’ is selected, Artifactory will request authentication parameters from the Maven client before trying to access this repository.
Deploying Artifacts Through Artifactory
Setting Up Distribution Management
To deploy build artifacts through Artifactory you must add a deployment element with the URL of a target local repository to which you want to deploy your artifacts.
To make this easier, Artifactory displays a code snippet that you can use as your deployment element. In the Artifacts module Tree Browser select the repository you want to deploy to and click Set Me UP. The code snippet is displayed under Deploy.
Remember that you can not deploy build artifacts to remote, so you should not use them in a deployment element.
Setting Up Security in Maven Settings
When deploying your Maven builds through Artifactory, you must ensure that any <repository> element in your distribution settings has a corresponding <server> element in the settings.xml file with a valid username and password as described in Configuring Authentication above. For the example displayed above, the Maven client expects to find a <server> element in the settings.xml with <id>artifactory</id> specified.
Anonymous access to distribution repository
If anonymous access to your distribution repository is allowed then there is no need to configure authentication. However, while it is technically possible, this is not good practice and is therefore an unlikely scenario
