Answer 1

You can try upgrading spring-security-oauth2-authorization-server to newer version 0.2.0

I ran into the same problem with client_secret_post , but then upgrading the version works for me.

Answer 2

What is the groupId of the artifact you are using? 0.1.2 appears to be the latest version of the groupId = org.springframework.security.experimental

If you change your groupId to org.springframework.security you'll see version 0.2.2 and higher
