While inspecting your build log, if you see the error message Error occurred during build: Authentication failed. Please run the "<jenkins_workspace>/klocwork/tools/bin/kwauth --url <host:port>" command to login., this means that Jenkins cannot find the proper credentials required to run the CI build.
