Dependency conflict with Spring boot

Hi, I am working on a spring boot project and we want to parse swagger yaml files.

First I tried adding this dependency to my project

        <dependency>
            <groupId>io.swagger.parser.v3</groupId>
            <artifactId>swagger-parser</artifactId>
            <version>2.0.17</version>
        </dependency>

and then making a parser object as such

        OpenAPI openAPI = new OpenAPIV3Parser().read("./swagger.json");

but I keep getting this error thrown when it tries to make the object.

Exception in thread "main" java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/JsonFactoryBuilder
	at io.swagger.v3.parser.ObjectMapperFactory.createJsonFactory(ObjectMapperFactory.java:41)
	at io.swagger.v3.parser.ObjectMapperFactory.createJson(ObjectMapperFactory.java:18)
	at io.swagger.v3.parser.ObjectMapperFactory.createJson(ObjectMapperFactory.java:14)
	at io.swagger.v3.parser.OpenAPIV3Parser.<clinit>(OpenAPIV3Parser.java:38)
	at io.datallama.api.SwaggerTest.main(SwaggerTest.java:11)
Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.core.JsonFactoryBuilder

	at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:522)
	... 5 more

Then what I did is I found a project on git hub that was already working (https://github.com/kalaspuffar/swagger-reader.git) and when I added the swing parent to his pom file I started getting the same error that is in my project.

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.5.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

Has anyone encountered this before or know how to fix it?

Start with the Maven POM dependency for io.swagger.parser.v3:swagger-parser and the Spring Boot 2.0.5.RELEASE parent, then inspect the resolved Jackson dependencies and dependency tree. Done means the Spring Boot project can instantiate OpenAPIV3Parser and read the Swagger file without the JsonFactoryBuilder NoClassDefFoundError.
