Click on the "maven projects" (make sure tool buttons are on) on the right side of intelij and then click on "Download Documentation".

Also, for future downloading you can go to the File -> Settings -> Build,execution, deployment, -> build tools -> Maven -> importing -> mark "Documentation" checkbox and apply settings
