Red colour in spring keyword in Intellij IDEA

Question

I couldn't solve the problem of SpringBoot Keyword which is highlighted in red in Intellij IDEA. I used the invalidates cache and synchronise option in IntelliJ but still not solved the problem.

POM.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>
        </plugins>
    </build>

</project>

Answer 1

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>

Answer 2

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.
