If you encounter the error "Package org.springframework.boot does not exist" in your Maven-based Spring Boot project, it means Maven cannot resolve Spring Boot dependencies. This issue commonly occurs due to incorrect Maven configuration, missing repositories, or incompatible dependencies.

In this guide, we’ll explore why this error happens and provide step-by-step solutions to fix it.

Why Does This Error Occur?

The error typically appears when:

  1. Spring Boot dependencies are missing in pom.xml.
  2. Incorrect or missing Maven repository (Spring repositories not configured).
  3. Maven project not properly loaded (IDE cache issue).
  4. Incorrect Java or Spring Boot version (version mismatch).
  5. Network/proxy issues (Maven unable to download dependencies).

Step-by-Step Fixes

1. Verify Spring Boot Dependencies in pom.xml

Ensure your pom.xml includes the Spring Boot Starter Parent and required dependencies:

Basic Spring Boot Maven Setup 

org.springframework.boot
        spring-boot-starter-parent
        3.2.0 
    

    
        
            org.springframework.boot
            spring-boot-starter

If Not Using spring-boot-starter-parent

If you’re not using the Spring Boot Parent POM, explicitly define Spring Boot dependencies:

org.springframework.boot
    spring-boot-dependencies
    3.2.0
    pom
    import

2. Check Maven Repositories

Maven needs access to Spring repositories to download Spring Boot dependencies. Ensure your pom.xml includes:

spring-milestones
        Spring Milestones
        https://repo.spring.io/milestone
    
    
        spring-snapshots
        Spring Snapshots
        https://repo.spring.io/snapshot
        
            true

3. Update Maven & Reload Project

Sometimes, the issue is due to IDE cache or Maven not syncing properly:

In IntelliJ IDEA

  1. Right-click on pom.xml → Maven → Reimport.
  2. File → Invalidate Caches → Restart IDE.

In Eclipse

  1. Right-click project → Maven → Update Project.
  2. Check "Force Update of Snapshots/Releases".

Command Line (if using terminal) 

mvn clean install -U

(-U forces Maven to update dependencies)

4. Check Java Version Compatibility

Spring Boot 3.x requires Java 17+, while 2.x works with Java 8+. Verify:

In pom.xml 

17

Check Installed Java Version 

java -version

If using an older Java version, upgrade JDK or downgrade Spring Boot:

org.springframework.boot
    spring-boot-starter-parent
    2.7.18

5. Fix Network/Proxy Issues

If Maven cannot download dependencies due to corporate proxy/firewall, configure Maven settings:

Edit ~/.m2/settings.xml 

corporate-proxy
            true
            http
            proxy.yourcompany.com
            8080
            your-username
            your-password

Final Working Example

Here’s a complete pom.xml that works with Spring Boot 3.2.0:

4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent
        3.2.0
    

    com.example
    demo
    1.0.0

    
        17
    

    
        
            org.springframework.boot
            spring-boot-starter
        
    

    
        
            spring-milestones
            Spring Milestones
            https://repo.spring.io/milestone

Conclusion

To fix "Package org.springframework.boot does not exist":

  1. ✅ Check pom.xml for correct Spring Boot dependencies.
  2. ✅ Ensure Maven repositories are properly configured.
  3. ✅ Reload Maven project in IDE.
  4. ✅ Verify Java version compatibility.
  5. ✅ Check network/proxy settings if dependencies fail to download.

Following these steps should resolve the issue. If the problem persists, check Maven logs (mvn clean install -X) for detailed errors.
