I used kdesrc-build to build the kde-pim group in a fresh kdepim-docker container. See https://community.kde.org/KDE_PIM/Docker for details on this Neon-based image; I had to install libyaml-libyaml-perl inside the container manually. After all 58 packages built successfully, I got the following (error?) message: Encountered an error in the execution of the script. The error reported was hash- or arrayref expected (not a simple scalar, use allow_nonref to allow this) at /home/neon/kdesrc-build/modules/ksb/BuildContext.pm line 829. at /usr/share/perl/5.22/JSON/PP.pm line 504.

I bet this is related to a first-use bug, let me see if I can reproduce. Thanks for the report as well!
Git commit 25e7bfc26fbacbfeb3875e75df02fa9409571d4e by Michael Pyne. Committed on 23/12/2017 at 23:13. Pushed by mpyne into branch 'master'. persistence: Fix regression in saving options. The move to JSON storage of persistent opts break first-time users, since the refactored code never actually gets around to setting a persistent_options key in the build context object. This seemed to work previously with Data::Dumper, but JSON::PP is not happy with being asked to serialize an undef. On the other hand I had always thought that sub setPersistentOption would have 'autovivified' the needed hash table, and the reporter's build process should have resulted in many calls to setPersistentOption over the build.
