Why JVM cannot find the definition of SpringApplication class?

Question

It might look like a duplicate of this question, but the solutions from it didn't work for me. I am getting an Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/boot/SpringApplication at com.example.demo.Application.main error when I try to run the application using spring-boot. My pom.xml:

JDK 1.8 and JRE 8 are installed on the system and worked fine before. I deleted the C:\Users\{username}\.M2\repository\org\springframework\boot directory on the system and forced Maven to reload the dependencies. Then I decompiled the file C:\Users\{username}\.M2\repository\org\springframework\boot\spring-boot\2.0.1.RELEASE\spring-boot-2.0.1.RELEASE.jar and still found it in it has this SpringApplication class that the JVM cannot find. I also explicitly added spring-boot-2.0.1.RELEASE.jar to the project, but the error remained the same. There is only a suspicion that I am using Open JDK, and not Oracle, which did not install on the system, but simply downloaded the deployed files and placed them in the folder I needed (the JDK installer for some reason does not work for me). Does anyone have any suggestions on what this problem may be related to?
