JodaTime - NoSuchMethodError: DateTimeFormatterBuilder.appendFixedDecimal

Question

While executing below piece of code

import com.github.fge.jsonschema.main.JsonSchemaFactory;

JsonSchemaFactory factory = JsonSchemaFactory.byDefault();

I am getting below error.

        <artifactId>json-schema-validator</artifactId>
        <version>2.2.6</version>
    </dependency>

Can someone please help me out to figure out what could be wrong?
