The default Coverity plugin credentials cannot be overridden with credentials scoped to a folder (when using the coverityIssueCheck or withCoverityEnvironment pipeline steps).

The pipeline syntax generator only lists global credentials. Even if I enter the credentials ID manually into the snippet, the step fails (see the message below). It works fine with global credentials.

 
java.lang.IllegalArgumentException: Username and password must be specified.
