NoUniqueBeanDefinitionException: defaultTextEncryptor, kmsTextEncryptor

When I add spring-cloud-config-aws-kms into the pom.xml, shown below, I have a not unique bean error.

I believe it is due to your first dependency, which includes a TextEncryptor (org.springframework.cloud.config.server.config.EncryptionAutoConfiguration$DefaultTextEncryptorConfiguration).

Looking at the current code in Spring Cloud, I think even though there is a ConditionalOnMissingBean, the default still gets loaded as it is loaded before the zalando lib?

I'd first try disabling spring.cloud.config.server.encrypt.enabled, and then if that didn't work, would move the zalando dep to the top of the pom.

Moving Zalando's dependency to top worked for me, thanks.
