package org.springframework.boot does not exist

I am trying to run a Small basic Spring boot program on my machine and I when I run clean compile (even before trying spring-boot:run) on maven I get the following Error :

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootPocApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootPocApplication.class, args);
    }

}

I tried many solutions I could find on internet, such as deleting the .m2 repository, adding different tags (version, fork,...) to the spring-boot-maven-plugin plugin which, I'm pretty sure, is the part causing the problem

Any suggestions ?

For those who have added all dependencies in pom.xml and still facing issue, try to run mvn dependency:tree in mvn console present in intellij or the terminal if you have maven installed. This resolved all the dependencies which were not earlier getting resolved by mvn clean install for me.

If you have this dependency below, but still you have this error:

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-web</artifactId>
</dependency>

your maven still doesn't download it, for this issue may you need to vpn or check internet connection. I have the same error and I use vpn, next in "Intelij IDE" in maven window( right side) if you can not see that, you should active that, next click on "reload All Maven project" and maven will download the library, then you can see your problem has been fixed. may it helpful.

If you are facing this issue in intellij, Go to pom.xml. Right click and select "Add as a Maven project". Then reload all maven projects from the maven tool present on the side. enter image description here

Had the same problem (using IntelliJ), and to solve it went through a variety of steps (not necessarily in this order), and my issue was solved:

  1. Make sure the pom.xml in your project directory has

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    

    For that one can also access the Dependencies by clicking ALT + Insert

    enter image description here

    Then search for spring-book-starter-web (or a similar variation), and click Add.

    enter image description here

  2. Invalidate all Caches (File > Invalidate All Caches)

    enter image description here

    enter image description here

  3. Remove the .idea folder in your project directory

    enter image description here

  4. Uninstall every Java: JDKs and Java 8, that I had installed.

    I've used Revo Uninstaller for this, but if one is in Windows, one can also go to Settings > Apps > Apps & features (as it says here).

    If one has, one might have to remove the directory .jdk as well.

    Then restart the machine.

  5. Install the JDK for the Project through IntelliJ.

    For that, go to File > Project Structure > Platform Settings > SDKs.

    enter image description here

    More on this here.

  6. Update IntelliJ to a newer version (assuming it's not up to date).

    As I use JetBrains Toolbox, just add to access it and it was straightforward.

    enter image description here

    One can also update by

  7. Make sure one has MAVEN_REPOSITORY pointing to the right place.

    Eg. C:\Users\goncalo\.m2\repository.

    Confirm that in File > Settings > Appearance & Behavior > Path Variables.

    enter image description here

  8. If the Project directory has a folder called target,

    enter image description here

    Go to the Maven (in my case it is on the right-top of the IDE) and, in the Lifecycle click clean

    enter image description here

    Then try to run the project again.

I was facing this issue and nothing was working out. I tried one of the solution to change maven home path. Intelij -> Preferences -> Build, Execution, Deployment -> Build Tools -> Maven

Here I changed the Maven home path from Use Maven Wrapper to Bundled (Maven 3) and everything became fine. enter image description here

sometime project got problem during compile or got problem. Step for the solution :

  1. check if the dependency is valid. On the topic, dependency is valid. Check the name on dependency to make sure, include the Hirarky.
  2. check your java. I tried using version 19 and it work fine then using 17 is fail!! but following example on youtube, the code work. Then the next step reload the project. Make sure your Java is up to date or newest.
  3. Reload project. This can be execute from command prompt (mvn -U idea:idea) or from your ide (on Intellij, choose your project folder -> maven -> reload project). You can try other way related to reloading your IDE. My recommendation is using command prompt. If you using IDE, try reload the project before close and open project.
  4. if nothing work.. delete .idea and then open and close your project (not recommended). When following step 3, your idea folder should be clean. Make sure your IDE not open this project before deleting the folder.
  5. use recommended IDE (related to reff link). This is just reminder.

notice: this tested on windows.

hint: sometime using lower version JDK can help. If you follow manual, try to use same version. My fault is using 19 not 17 (on youtube). The newest version have more advance than before, if you still learning following your mentor/teacher is recommended.

summary from here:

Importing to IntelliJ - Error package org.springframework.boot does not exist

If you don't need web related libraries, you can add this dependency instead of spring-boot-starter-web mentioned in other answers:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>

If any Wrapper folder is present inside .mvn folder of your project delete it. Also, Go to File->Settings->Build,Execution,Deployment->BuildTools->Maven->Set Maven home path as Bundled(Maven 3)

1) Close the project 2) Import the project again with auto-import checked

This worked for me. Maybe works for you too.

You need add this dependency

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

then it will work.

Add the below section outside dependency management and do an update of project. And then the clean install of maven.

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.10.RELEASE</version>
    </parent>

And the below dependency.

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

If does not fix (Not Likely to happen) then add the other dependencies mentioned here

You have 0 compile dependencies, only test-compile dependencies defined, because you've commented out spring-boot-starter-data-jpa. Spring starter's pull other dependencies in (including other starters) to create everything needed at compile time. Un-comment the spring-boot-starter-data-jpa dependency, and/or re-evaulate what dependencies you actually want.
