Biblatex is a fantastic bibliography/citation manager for LaTeX. It trumps the older bibtex for its much easier customizability and configuration. It does however, have one bug that can be very perplexing to figure out due to the misleading error message that results: “Could not find all biber source files”. At first glance this message seemed straightforward enough to send me poking about the project file structure and build system, checking paths and names.
Most of the existing approaches to integrating LaTeX compilation into a LaTeX writing workflow centered around a text editor (as opposed to a fancy-schmancy IDE) are horrendously bloated creatures, aggressively and voraciously hijacking so many key-mappings and normal functionality that it makes your Vim feel like it is diseased and is experiencing a pathological personality disorder of some kind. Yes, LaTeX-Suite, I am looking at mainly at you. I did not want a platoon of obnoxiously cheery elves to insert two hundred environments into the document while a marching band parades around the room when I hit the \$ key.
