If the error indicates the Maven repository issue, such as the Failed to update Maven indices error, try to check if Maven repositories were indexed correctly. The indexes are fetched remotely from remote repositories. Some repositories do not provide indexes, or do not keep an updated index, for example, repositories from Bintray , in this case you can ignore the error.
If you have an indexed repository, but still get a Maven repository error, check the following options:. On the Maven page, in the User settings file field, check if you defined proper credentials for the server in settings.
On the Repositories page, click Update to update Maven repositories. You can check your local maven repository in the Maven Repositories settings and try to update it.

Artifactory displays a distributionManagement snippet already configured for the repository you selected. Just run: mvn clean install. As you run the build, you will see that Maven is resolving artifacts through Artifactory.
If you also need to deploy artifacts, Artifactory comes with a set of plugins that allow common CI servers such as Jenkins, TeamCity and Bamboo to direct the build output to Artifactory. You can even see it in action in this screencast. Artifactory still offers all the benefits presented in the original article and then some:.
Reliable and consistent access to remote artifacts: As a proxy for remote repositories, Artifactory caches remote artifacts locally, so you are not dependent on the network or remote resources. Optimized builds through reduced network traffic: Builds are faster since all remote artifacts are accessed from the local cache without any external networking.
Full integration with any build ecosystem: Through a series of plugins, Artifactory supports fully automated builds using common CI servers both on-premises and in the cloud. Security and access control: Artifactory provides fine-grained access control from the level of a complete repository down to a single artifact.
