Selecting a Maven metadata file (
maven-metadata.xml) or a POM file (
pom.xml) from the Tree browsing mode in the Artifact Repository Browser, provides you with details on the selected item.

To configure Maven to resolve artifacts through Artifactory you need to modify the
settings.xml. You can generate one automatically, or modify it manually.
To make it easy for you to configure Maven to work with Artifactory, Artifactory can automatically generate a
settings.xml file 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.
The Automatically Generating Settings will only allow to you to configure Virtual Maven repositories. While this is a best practice and the recommended method, you may change any repository by manually editing the
Once you have created your Maven repository, go to Application | Artifactory | Artifacts, select your Maven repository and click Set Me Up.
In the Set Me Up dialog, 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, click Generate Settings to generate and save the
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.
For more details, please refer to the Provisioning Build Tool Settings under Filtered Resources.
To override the built-in central and snapshot repositories of Maven, you need to ensure that Artifactory is correctly configured so that no request is ever sent directly to them.
You can use the automatically generated
To do so, you need to insert the following into your parent POM or
settings.xml (under an active profile):
<repositories> <repository> <id>central</id> <url>http://[host]:[port]/artifactory/libs-release</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>snapshots</id> <url>http://[host]:[port]/artifactory/libs-snapshot</url> <releases> <enabled>false</enabled> </releases> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>central</id> <url>http://[host]:[port]/artifactory/plugins-release</url> <snapshots> <enabled>false</enabled> </snapshots> </pluginRepository> <pluginRepository> <id>snapshots</id> <url>http://[host]:[port]/artifactory/plugins-snapshot</url> <releases> <enabled>false</enabled> </releases> </pluginRepository> </pluginRepositories>
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.
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:
<mirrors> <mirror> <id>artifactory</id> <mirrorOf>*</mirrorOf> <url>http://[host]:[port]/artifactory/[virtual repository]</url> <name>Artifactory</name> </mirror> </mirrors>
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.
For more information on using mirrors please refer to in the Apache Maven documentation.
Artifactory requires user authentication in three cases:
Authentication is configured in Maven using
<server> elements in the
Each <repository> and <mirror> element specified in the file must have a corresponding <server> element with a matching <id> that specifies the username and password.
The sample snippet below emphasizes that the
<repository> element with
id=central has a corresponding
<server> element with
<repository> element with
id=snapshots has a corresponding
<server> element with
The same would hold for <mirror> elements that require authentication.
In both cases the username is
admin and the password is encrypted.
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:
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
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.
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 Artifact Repository Browser, click Tree and 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.
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
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
