~~I have managed to resolve this issue by changing Report Path from "target" to "target/" But this is odd.~~ Update: this does not helped - NPE happens sporadically.

Having a similar (the same?) issue since upgrading to 3.5.0 - in a traditional Maven project I've not got the Report Path set at all, the error is:

java.lang.NullPointerException

After downgrading to 3.4.0 the build passes and results are correctly published.

~From a pipeline build I'm getting a very similar NPE (not identical though). Weirdly enough the error is not in the Jenkins job log but inside of the cucumber report! screenshot from 2017-02-14 20-16-49~

edit: clarification + crossed out pipeline stacktrace as it turned out to be unrelated to the version change.

We're experiencing the same issue:

Downgrading from 3.5 to 3.4 solved the issue.

OK, i'm not sure why it happens but I know how to fix it. Will be in next release.

In the meantime the workaround is to just edit job configuration and save it again - then it will probably save empty collection, not null reference
