BlueOcean JavaScript Error

[John D. Ament]

Was recommended to try the blue ocean plugin for jenkins.  After setting it up, in my existing jenkins instance.  I get the screen "No pipelines found" even though I have pipelines, and found the following javascript error:

jenkins-js-extension.js:15863 SyntaxError: Unexpected token 

 in JSON at position 10362880(anonymous function) @ jenkins-js-extension.js:15863

jenkins-js-extension.js:15863 SyntaxError: Unexpected token (…)(anonymous function) @ jenkins-js-extension.js:15863

One more thing.  Hitting this endpoint: /blue/rest/search/?q=type:pipeline;excludedFromFlattening:jenkins.branch.MultiBranchProject

has this stacktrace in it:

[Baptiste Mathus]

Just to be sure. Which version/how did you try it? Docker image? From sources? Experimental update center?

Thanks

Experimental update with Jenkins 2.15. looks like a compatibility issue with cucumber though.

[John D. Ament]

Removing cucumber did fix it.

I've submitted pull request https://github.com/jenkinsci/junit-plugin/pull/84 which should prevent the ClassCastException from happening.
