Maven on the intellij was unavailable(think removed).I can not make new maven project or import dependency form pom.xml using: right click->maven->reImport.No maven option exist when right click.
It looks like the installation iscorrupted.
Remove the .IntellijXX or .IdeaICXX settings folder, which can be found under in the current user directory and after restarting Intellij, it should recreate everything fixing the problem.
