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...

Solution 1

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

Solution 2

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').

Solution 3

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

Solution 4

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.

Solution 5

Project root directory -> right click -> Add Framework Support --> Maven or Gradle --> Click Ok

You didn't add the Spring .jar files to the classpath?

[Antoine Grenard]

Arf ! I didn't knew it wouldn't be done automatically .. I've searched and found how to do it thx to you :)

"Cannot resolve symbol 'String'" - looks like your Java installation is broken or you have not configured the JDK in Intellij

[Antoine Grenard]

Mmmhh it is kind of strange cause when i go into project structure the jdk 1.8 appear ..

[Antoine Grenard]

My JDK Wasn't configured as it should have been i've found how to do it properly here : stackoverflow.com/questions/4618794/…

[Antoine Grenard]

After that i've decided to delete all and redo it again and it work like magic :)

This question does not appear to be about programming within the scope defined in the help center.

[Mohamed Bouguerra]

Your are missing some dependencies. Try this ! stackoverflow.com/questions/35293116/…

[Scott Greenup]

This worked perfectly for me. I had created the project based on a new Maven project, and while I could use mvn on the CLI, Intellij was showing me the errors that Atoine had.

[KansaiRobot]

there is no spring MVC. Only Groovy

[KansaiRobot]

Did this,. Nothing changed

[KansaiRobot]

Non-resolvable parent POM for the SNAPSHOT

Could not find "spring" in the list of framework support

I have faced the same issue as the OP. I had started the project from the scratch using IntelliJ IDE and spring initializer. The maven wasn't installed separately even though it was available as part of the project. I installed maven separately from this link maven.apache.org/download.cgi. Run the above command and it worked for me.

You will find "Spring" only in the Intellij Ultimate Edition. You can go with "Application" in the configuration.

I couldnt find it
