JDBC driver class not resolved in Spring Boot application.yml during code analysis

In IntelliJ IDEA 2018.2.6, when IDEA makes a code analysis of my Spring Boot application.yml with this JDBC driver config:

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.zaxxer.hikari.HikariDataSource

it complains with

Error:(23, 28) Cannot resolve class or package 'mysql'
Error:(23, 34) Cannot resolve class or package 'cj'
Error:(23, 37) Cannot resolve class or package 'jdbc'
Error:(24, 15) Cannot resolve class or package 'zaxxer'
Error:(24, 22) Cannot resolve class or package 'hikari'

Is there any way to avoid this?

I use:
