In my instance it said "Problems: No versions available for XXX" or "Failed to read descriptor for artifact org.xy.z" ref: You can actually see the real failure by mousing over the project name itself. If the dependencies are all underlined in red, "Houston, we have a problem". Then expand one of your maven projects and its dependencies. You can tell if this is the case by opening the maven projects tool window (View menu -> Tool Windows -> Maven Projects). The cause was that sometimes IntelliJ "doesn't parse maven dependencies right" and if it can't parse one of them right, it gives up on all of them, apparently.

Ran into this again, with IntelliJ 15 this time, which has no "use maven3 to import" option available anymore. Ref: (which may have a few other ideas too) Fix IntelliJ 15+ The Import Maven Projects automatically setting has been moved to Build, Execution, Deployment > Build Tools > Maven > Importing in your IntelliJ preferences.įile -> Settings -> maven -> importing and uncheck "use maven3 to import project"
