In https://github.com/JuliaPackaging/BinaryBuilder.jl/blob/bb322ce60a4f8a0a6bf3c657043b47878b9f1785/src/AutoBuild.jl#L1171, the reg-exp doesn't recognise artifacts with a build number, e.g. `MyLibrary.v1.0.0+2.x86_64-linux-gnu-cxx11.tar.gz` (the missing part is `+2`) Hackaround: ``` tarball_filename_match = match(r"^(?<name>[\w_]+)\.v(?<version>\d+\.\d+\.\d+)(\+\d+)?\.(?<platform_triplet>([^-]+-?)+).tar", tarball_filename) ```
