IntelliJ: Cannot resolve symbol 'springframework'

Question

I'm trying to start my first project with Spring. I use IntelliJ idea and I'm kind of new to it too. But anyways, I followed the step written on the Jetbrains website and I don't know what I have done wrong, but I got a lot of errors on the first to files that are created by default.

BloomBookingApplcation.java

package com.bloombooking;  import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;  @SpringBootApplication public class BloomBookingApplication {      public static void main(String[] args) {         SpringApplication.run(BloomBookingApplication.class, args);     } }  Error:(3, 12) Cannot resolve symbol 'springframework' Error:(4, 12) Cannot resolve symbol 'springframework' Error:(6, 2) Cannot resolve symbol 'SpringBootApplication' Warning:(7, 1) Access can be packageLocal Error:(9, 26) Cannot resolve symbol 'String' Error:(10, 3) Cannot resolve symbol 'SpringApplication' 

Maybe I'm stupid but I don't know which step I've missed...

How can I fix this?

I have found the way to add spring with the quickfix button.

But now I have got new errors I don't understand why... I should maybe download it directly and put the libraries one by one maybe?

Error:(3, 28) Cannot resolve symbol 'boot' Error:(4, 28) Cannot resolve symbol 'boot' Error:(6, 2) Cannot resolve symbol 'SpringBootApplication' Warning:(7, 1) Access can be packageLocal Error:(9, 26) Cannot resolve symbol 'String' Error:(10, 3) Cannot resolve symbol 'SpringApplication' 

Or maybe it's my IntelliJ idea which isn't configured right since I don't have any completion anywhere and I can't create packages...

Click on refresh button .Maven may not be able to sync properly

I had the same problem, and this is how it worked for me:

On the source root directory -> right click -> Add Framework Support.

A window will open with different categories, such as Java EE, JBoss etc. Go to 'Spring' category. Then, download the pack of libraries that you need (I used 'Spring MVC').
