OK, seems to be clear now: `install` doesn't play nicely (even locally) with the Checkstyle plugin if the latter is bound to the `validate` phase.
Trying `clean install checkstyle:checkstyle -e -pl resources,core` with a branch that moves the invocation back to the default `verify` phase: https://jclouds.ci.cloudbees.com/job/DEBUG-jclouds-checkstyle-verify-phase/5/ (can't use the PR builder for this as that only runs `verify`...) --- Reply to this email directly or view it on GitHub: https://github.com/jclouds/jclouds/pull/551#issuecomment-58133973
