Spring Cloud Vault without Spring Boot in OSGi environment

Is it possible to use Spring Cloud without using Spring Boot? I am asking this because I need to use Spring Cloud Vault (https://cloud.spring.io/spring-cloud-vault/reference/html/) but my runtime environment (Apache Karaf) doesn't support the use of Spring Boot, because the app is deployed in bundles (modules) in a OSGi environment. Also all the examples in the docs are using Spring Boot. Thank You.
