Project 'org.springframework.boot:spring-boot-starter-parent:2.4.0' not found
Solution 1
I just ran into a similar problem. I'm using IntelliJ IDEA Ultimate 2020.2. The version number 2.4.0 was red and the message was the same as yours.
Selecting File -> Invalidate Caches / Restart... and choosing the Invalidate and Restart option fixed the issue. I guess it was just a stale cache.
Solution 2
Spring Boot's starter parent pom certainly does exist in Maven Central.
I copied your pom.xml
and ran mvn test
using Maven 3.6.3. All required libraries, including the parent pom were downloaded just fine. You will probably want to look at your ~/.m2/settings.xml
file to see if any proxies are active that are preventing you from connecting to Maven Central.
Solution 3
What worked for me was re-building and remote caches and then local caches. Here're the steps I followed (on Mac, please translate to your target environment):
- Goto Preferences Menu: ie: IntelliJ IDEA > Preferences
- Under Build Tools: ie: "Build, Execution, Deployment" > Build Tools
- Select Repositories: ie: Maven > Repositories
- Notice the Remote and Local repositories, and the Update button
- Select Each repository and click Update. This will take a while depending on your internet speed, but it will do a complete check of the broken downloads and stale Maven caches
Solution 4
Just reload your Maven project in the IDE. It will work.
