Cannot resolve JacksonTableTransformer for Cucumber 4.x.x

Following this example, I am converting Cucumber 3.x.x datatable configurer to Cucumber 4.2.0 using JacksonTableTransformer but is saying it cannot be resolved to a type.

Configurer

import io.cucumber.datatable.dependency.com.fasterxml.jackson.databind.ObjectMapper;

public class Configurer implements TypeRegistryConfigurer {

    @Override
    public Locale locale() {
        return Locale.ENGLISH;
    }

    @Override
    public void configureTypeRegistry(TypeRegistry registry) {

        // Just added these 2 lines for Cucumber 4.2.0
        JacksonTableTransformer jacksonTableTransformer = new JacksonTableTransformer();
        registry.setDefaultDataTableEntryTransformer(jacksonTableTransformer);

        /*
         * Maps DataTable with header row to multiple objects of Type<T>. Each row below
         * the header is an object.
         */
        registry.defineDataTableType(new DataTableType(Transaction.class, new TableEntryTransformer<Transaction>() {
            @Override
            public Transaction transform(Map<String, String> entry) {
                return new Transaction(entry);
            }
        }));

        /*
         * Maps DataTable with label column to a single object of Type<T>. Left column
         * is field name, right column is value.
         */
        registry.defineDataTableType(new DataTableType(Transaction.class, new TableTransformer<Transaction>() {
            @Override
            public Transaction transform(DataTable table) throws Throwable {
                return new Transaction(table.asMaps().get(0));
            }
        }));

    }

}

I only have 2 datatables and the configurer works for 3.x.x and 4.x.x if I remove the 2 lines added. I do want to use the object mapper though.

  • Following this example, I am converting Cucumber 3.x.x datatable configurer to Cucumber 4.2.0 using JacksonTableTransformer but is saying it cannot be resolved to a type.

    If you read the full class file that you linked you'll find that JacksonTableTransformer is defined at line 99. I.e. you will have to define this class yourself.
