hackrf_sweep_spectrum_analyzer.jar doesn't exist

[Allasso]

Trying to build on Ubuntu 18.04 according README instructions.

14:08:01 : ~/hackrf2
git clone --depth=1 --recurse-submodules https://github.com/pavsa/hackrf-spectrum-analyzer.git
cd hackrf-spectrum-analyzer/src/hackrf-sweep/
make
build/hackrf_sweep_spectrum_analyzer.sh
Error: Unable to access jarfile build/lib/hackrf_sweep_spectrum_analyzer.jar

Search for hackrf_sweep_spectrum_analyzer.jar yields nothing

find . -name hackrf_sweep_spectrum_analyzer.jar
find ../../ -name hackrf_sweep_spectrum_analyzer.jar

I've hunted around for it here in the online repo and I think I see how the filename was generated in the Makefile: https://github.com/pavsa/hackrf-spectrum-analyzer/blob/master/src/hackrf-sweep/Makefile

but I can't seem to find the file itself
