We are seeing this on jenkins 2.7.4 on windows as well.

What was your script? Steps to reproduce from scratch? Did you check the recommended syntax in Snippet Generator? Perhaps related to a fix abayer made to parsing of single-argument steps.

We have the same problem and our script is:
publishHTML(target: [ reportName: 'HTML Test Report',
allowMissing: false,
alwaysLinkToLastBuild: false,
keepAll: true,
reportDir: 'fastlane/test_output',
reportFiles: 'report.html'])

it seems, that we should use another syntax, generated by Snippet Generator
I tested variant without "target"

publishHTML([reportName: 'HTML Test Report',
allowMissing: false,
alwaysLinkToLastBuild: false,
keepAll: true,
reportDir: 'fastlane/test_output',
reportFiles: 'report.html'])

and it's working
