In maven central repo, there is only 2.2.0-Relase which is available. https://central.sonatype.com/artifact/io.pivotal/pivotal-cloudfoundry-client-reactor/2.2.0.RELEASE/versions
But scdf has a dependency on io.pivotal:pivotal-cloudfoundry-client-reactor:jar:2.1.0.RELEASE
org.springframework.cloud spring-cloud-dataflow-platform-cloudfoundry 2.10.0 ->
org.springframework.cloud spring-cloud-deployer-cloudfoundry 2.8.0 ->
io.pivotal pivotal-cloudfoundry-client-reactor 2.1.0
I suppose that maven try to download this dependency from https://repo.spring.io/libs-snapshot. But now this is impossible : Not authorized -> [Help 1]
I can build as i'm lucky to have this dependency in my local repository, probably because i builded scdf a few month ago.

2.10.3 release can be built without this problem (the problem was with 2.9.1 release). It seems that Pivotal has changed a lot of things between 2.9.x et 2.10.x and probably fixed some errors and refactor dependency management.
