I just got a new pc so I set up intellij on the new pc. It seems like it is set up identical to my old but it does not seem to be able to find the basic java.lang classes. I have done all of the settings stuff for setting up the sdk, including the project and module SDKs. In the platform settings screen I can do maven builds just fine but when I look at files via the editor and when I do individual compiles, it says that these basic java classes cannot be found. I would appreciate any feedback as to other things I can try.
