I am using the Pipeline plugin to setup a workflow using a script.
To publish the checkstyle report, I use this line:

    step([$class: 'CheckStylePublisher', pattern: '**/scalastyle-result.xml', unstableTotalAll: '0', usePreviousBuildAsReference: true])

The checkstyle warnings show up in the build but the "Checkstyle Trend" on the main build page is missing. (See attached).
Also the checkstyle warnings link does not show up on the main build page.

Let me know if more info is needed
