I installed devstudio 11.1.0.AM3 B1225 and when I launched it there was a cdk server adapter already set up. That's completely normal. But what's wrong is that it's the new 3.2+ adapter whereas what I have actually installed in ~/.minishift is version 3.1.1.
The runtime detection should be able to detect the version in ~/.minishift/cdk and return a match only if the version is compatible with the given adapter.

jkopriva@redhat.com says cdk 3.1.1 cannot be launched with cdk 3.2+ adapter. I cannot really check that myself because my server adapter doesn't have minishift binary set up by default and you validate the version in the server editor, so I can't use 3.1.1 with the 3.2+ adapter.
