Failed to execute goal Could not exec java

Recently I was upgraded spring-boot version 1.5.x to 2.4.3. After upgrading spring-boot it won't start.

ran command mvn clean spring-boot run

Then spring throw the error :

Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.4.3:run (default-cli) on project sample-project: Could not exec java

Java version : 1.8 Maven version : 3.6.3

If any information is required then please comment, I will update the question as per the requirement.
