Java 11 + ActiveMQ 5.15.14 = java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/ObjectMapper

Não consegui rodar o ActiveMQ na versão usada no curso (5.12.0) porque dá um erro que, acredito eu, tenha a ver com a versão do Java que eu utilizo (a 11.0.9.1). Tive que usar uma versão mais recente, e estou usando a 5.15.14.

Sigo as instruções das aulas rigorosamente. Estou na aula "02. Consumindo mensagens com JMS". Coloco o ActiveMQ pra rodar usando o comando no bash que a aula especifica. Mas, quando vou rodar o projeto no Eclipse, o console exibe o seguinte erro:
