spring-cloud-aws-context dependencies

[pacey]

I'm using org.springframework.cloud:spring-cloud-aws-context:1.2.1.RELEASE and at runtime my application cannot find any of the cache related classes e.g.

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'java.util.List<org.springframework.cloud.aws.cache.CacheFactory>' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

All the dependencies for Elasticache are also missing for me, even though the reference doc says all the necessary dependencies are dealt with.

Strangely, if I remove my explicit dependency on spring-cloud-aws-context then I get a different error

I then added the explicit dependency on com.amazonaws:aws-java-sdk-elasticache:1.11.125 and it threw the original error I had.

My spring-cloud dependencies are:

compile('org.springframework.cloud:spring-cloud-starter-aws:1.2.1.RELEASE')
compile('org.springframework.cloud:spring-cloud-aws-autoconfigure:1.2.1.RELEASE')
compile('org.springframework.cloud:spring-cloud-aws-messaging:1.2.1.RELEASE')

You can see from running gradle dependencies that the elasticache aws sdk is not provided by the module. It's not a massive issue as it can be declared manually, but the library provides all the others so I'd rather it be consistent.

There is no mention of com.amazonaws:aws-java-sdk-elasticache:1.11.125 below:
