IntelliJ: Cannot resolve symbol 'springframework'

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...

IntelliJ (File > Settings > Build,Execution,Deployment > Build Tools > Maven )

change maven home path to "user maven wrapper".

It worked for me.

First open maven window from right panel

then click maven settings

next change maven home path

after that reload maven project with this

if this maven home path is not working you can change it to another home path for checking

Just restart your IDE (Intellij) and it should ask you to start loading of the maven project. It worked for me.

What works for me was to close Intellij, erase the idea folder and open it again, Intellij seems to check everything again and then my dependency hasn't any issues

I had a few spring-boot modules which were in perfect running state, but suddenly my PC went off and that created issues like: cannot resolve symbol 'springframework' and etc

[Maven -> Reload all maven projects] : this fixed the issue

Right click on the project and select Open In → Terminal

In the terminal, type → mvn -U idea:idea

It will resolve all the classpath issues for the particular project

Maven did not added dependencies on intellij so for this problem I restarted intellij IDE and when this time IDE stared it added dependencies successfully.

In my case triggering an Invalidate Caches/Restart helped IntelliJ now find those dependencies.

Following what Mr. BlueSky told in his answer here, I could get the dependencies downloaded. Actually, the answer by Vinayak Shedgeri should have helped too. For those whom it didn't, you could try the invalidate cache/restart.

P. S.: And going by what could have caused this behavior, you could very well try something as simple as relaunching IntelliJ first. Just a guess.

Check if

/Users/<userName>/.m2/

location has settings.xml and toolchains.xml. I think toolchains might not be necessary but settings.xml is required. Instructions for creating settings.xml can be found here - https://maven.apache.org/settings.html

My issue was resolved after adding settigs.xml and toolchains.xml to above mentioned location and restarting the IDE.

Please check if you have configured Maven Settings.

IntelliJ (File > Settings > Build,Execution,Deployment > Build Tools > Maven )

Maven home path : C:/Program Files/apache-maven-3.6.0

It resolved my error.

In my case, I was behind Office proxy and that why MAVEN was unable to download the required dependencies on its own !

After switching the network and executing below command : mvn clean install -U, it worked !!

Add dependency for springframework in pom.xml and run below command from directory where pom.xml exist.

mvn clean install -U

Above command will forcefully download the dependencies.

if you are behind proxy then try below command

mvn clean install -DproxySet=true -DproxyHost=www-proxy.us.com -DproxyPort=80

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').
