userInfoRestTemplateFactory in ResourceServerTokenServicesConfiguration required a single bean, but 4 were found

Question

I'm upgrading a cloud app using Oauth from spring-boot 1.5 to 2.2.4. It works locally but fails on deploying to PCF.

Below are the dependencies. My first suspicion would be version incompatiblity haven't been able to trace a conflict with these so far. Can anyone offer direction?

org.springframework.cloud:spring-cloud-starter-oauth2:jar:2.2.0.RELEASE
org.springframework.security.oauth:spring-security-oauth2:jar:2.4.0.RELEASE
org.springframework.boot:spring-boot-starter-oauth2-resource-server:jar:2.2.4.RELEASE
org.springframework.security.oauth.boot:spring-security-oauth2-autoconfigure:jar:2.1.2.RELEASE
org.springframework.security:spring-security-openid:jar:5.2.1.RELEASE
io.pivotal.spring.cloud:spring-cloud-services-starter-config-client:jar:2.2.0.RELEASE

Method userInfoRestTemplateFactory in org.springframework.boot.autoconfigure.security.oauth2.resource.ResourceServerTokenServicesConfiguration required a single bean, but 4 were found:

This was caused by duplicates of this library being pulled in. After removing the duplicate the issue went away.

<dependency>
  <groupId>org.springframework.security</groupId>
  <artifactId>spring-security-oauth2-resource-server</artifactId>
</dependency>
