Given this directory structure:

./target
./target/com
./target/com/futureproofretail
./target/com/futureproofretail/utils
./target/com/futureproofretail/utils/GenericAvroDeserializer.class
./target/com/futureproofretail/utils/GenericAvroSerde.class
./target/com/futureproofretail/utils/GenericAvroSerializer.class

I'm running code with jruby service.rb

It fails on

java_import 'com.futureproofretail.utils.GenericAvroSerde'

NameError: cannot load Java class com.futureproofretail.utils.GenericAvroSerde
        from org/jruby/javasupport/JavaClass.java:286:in `for_name'

I've tried adding

$LOAD_PATH << '/Users/machty/code/exc/exc-kafka-consumer/target/com/futureproofretail/utils/GenericAvroDeserializer.class'
$LOAD_PATH << '/Users/machty/code/exc/exc-kafka-consumer/target/com/futureproofretail/utils/GenericAvroSerializer.class'
$LOAD_PATH << '/Users/machty/code/exc/exc-kafka-consumer/target/com/futureproofretail/utils/GenericAvroSerde.class'

$CLASSPATH << '/Users/machty/code/exc/exc-kafka-consumer/target/com/futureproofretail/utils/GenericAvroDeserializer.class'
$CLASSPATH << '/Users/machty/code/exc/exc-kafka-consumer/target/com/futureproofretail/utils/GenericAvroSerializer.class'
$CLASSPATH << '/Users/machty/code/exc/exc-kafka-consumer/target/com/futureproofretail/utils/GenericAvroSerde.class'

What do I need to change? How can I debug stuff like this?
