At first I've just thought that there are no open issues for this plugin, but when I clicked the Edit tab on the issue list for this plugin I got an error message telling me that:
"The value 'build-blocker-plugin' does not exist for the field 'component'.
I also tried finding the component using the autocomplete feature, but I couldn't find it, so it is either called something really un-intuitive or it is completely missing.
