Failed to process import candidates for configuration class inorder to use log4j2.17.1 while migrating SpringBoot from 1.3.6 to 2.6.3 using maven

Question

I want my project to use log4j2.17.1 for which I need to upgrade the spring-boot version from 1.x to the latest one i.e. 2.6.3. After adding dependencies the build is running fine But while running server I am getting the error:-

ERROR org.springframework.boot.SpringApplication - Application run failed org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [my_spring_project_name]; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.integration.config.IntegrationRegistrar]: Unresolvable class definition; nested exception is java.lang.ExceptionInInitializerError
