I am trying to build a Kogito 1.13.0.Final business process project where I am using the Jackson 2.11.2 object mapper 
in a script task with the following dependencies in the pom:

   <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-core</artifactId>
      <version>${version.jackson}</version>
    </dependency>
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-databind</artifactId>
      <version>${version.jackson}</version>
    </dependency>

I get the error 

java.util.concurrent.CompletionException: java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/PropertyNamingStrategies

...

The class com/fasterxml/jackson/databind/PropertyNamingStrategies is actually present in the corresponding jar in my Maven
repository. Is there a way to resolve this?

If you are using Quarkus, bring in the quarkus-jackson extension instead.
Moreover, version 1.14 just shipped with a few jackson-related fixes, use Quarkus 2.5.1 to get it

I moved the code from a script task to a service task and the error went away. 

I will check the quarkus jackson extension anyway.
