:syncWithRepo FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':syncWithRepo'.
> Process 'command '/usr/java/jdk1.8.0_92/bin/java'' finished with non-zero exit value 1

Going to /crumbIssuer/api/json shows the correct response, e.g.

{"_class":"hudson.security.csrf.DefaultCrumbIssuer","crumb":"xxx","crumbRequestField":"Jenkins-Crumb"}
but maybe it's not parsed correctly.

Related: #98, #20

The code fails in JenkinsApi.groovy on deleteJob():

    http.post(path: path, body: postBody, query: params,
            requestContentType: contentType) { resp ->
        assert resp.statusLine.statusCode < 400
        status = resp.statusLine.statusCode
    }
