JARs of many frameworks and their dependencies get updated too often now. But you do not want to turn your project into a Maven project just because of this? Then this feature is just for you.

You can add your company repository to the list of searched repositories, if it is managed by Nexus, by providing the Nexus URL in Settings | Maven | Repository Indices | Nexus Locations list.
