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.

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):

  1. Goto Preferences Menu: ie: IntelliJ IDEA > Preferences
  2. Under Build Tools: ie: "Build, Execution, Deployment" > Build Tools
  3. Select Repositories: ie: Maven > Repositories
  4. Notice the Remote and Local repositories, and the Update button
  5. 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

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.

Just reload your Maven project in the IDE. It will work.

Probably you are trying to run mvn spring-boot:run directly.

You can use the wrapper instead cf. ./mvnw spring-boot:run This should fix your problem.

In my case mvn clean and than mvn package helped me with the same problem.

Short Answer: Double check if your internet provider is blocked maven repohttps://repo.maven.apache.org/maven2/ site mistakenly.

I also encounter with this problem. For my case, I tried everything, like invalidate cache and restart Intellij, re-import the maven dependencies. But those are not working for me.

When I try to re-import the maven dependencies with my mobile data, then everything is okay. So, there was a problem with my internet provider.

After I inform them, then I was fixed. Thanks
