because fabric8-maven-plugin is incompatible with Maven 3.5.x
examples/quickstarts such as Fuse Tooling one and this one are reproducing the issue. it means that no quickstarts targeting OpenShift is working as they are using fabric8-maven-plugin (as far as i know)

[ERROR] Failed to execute goal io.fabric8:fabric8-maven-plugin:3.5.34:resource (default) on project spring-boot-camel-xml: Execution default of goal io.fabric8:fabric8-maven-plugin:3.5.34:resource failed: A required class was missing while executing io.fabric8:fabric8-maven-plugin:3.5.34:resource: org/fusesource/jansi/Ansi$Color

extra problem, Eclipse Photon which will be released tomorrow is embedding Maven 3.5.2 by default.
