can you show your pom file? Also, try reimporting resources. right click on your module -> maven -> reimport — Pranali Rasal, Jul 30 '19 at 11:34

Here is the solution, guys. I found it on stackoverflow.

I fixed the problem adding the version of the plugin in the pom.xml, which is the same of spring boot's version.

<groupId>org.springframework.boot</groupId> 
<artifactId>spring-boot-maven-plugin</artifactId> 
<version>${project.parent.version}</version>

I had same problem. I inserted this line:

<version>2.4.1</version>

under the

<artifactId>spring-boot-maven-plugin</artifactId>

line, then loaded Maven changes (when little blue Maven icon popped up), red text became white (grey, etc.), seems ok now.
