Solution

SnakeYAML is a YAML-parsing package that offers a high-level API for YAML document serialization and deserialization. The Yaml class, like the ObjectMapper class in Jackson, serves as the entry point for SnakeYAML.

Data is in a POJO object in Java. Create an object mapper using the YAML implementation class’s writeValue method, which turns a POJO object into a YAML file. Finally, the YAML format is used to serialize POJO data.

The solutions to the above problems relate to the SnakeYaml which you are including in the JAR. If you are not including the SnakeYaml in your JAR file you need to do the following steps to solve the above problem: 

• Use Maven’s uber-jar plugin to include it,
• Use Maven’s uber-jar plugin to include it, the YAML JAR’s classpath when executing the JAR,
• or the exec plugin when launching the JAR to enable dependency detection.

Another solution is to add the dependency plugin which is a necessity for the packing.
