building with ant fails in get-buck-info

Over a fresh git pull of buck. Any advice?

gen-buck-info:
     [exec] Traceback (most recent call last):
     [exec]   File "programs/gen_buck_info.py", line 51, in <module>
     [exec]     sys.exit(main(sys.argv))

     [exec]     o.__class__.__name__)

Any quick advice?

@matanster, there is no such thing as Buck for Nuclide - there is just Buck. Nuclide can use it underneath for some of its plugins, but it’s the same binary and the same set of steps to install.

As to why Facebook and all other companies with huge internal repositories use Buck-like build tools instead of Make/Maven/Gradle-like ones, you can read on our main page https://buckbuild.com/ In short - those tools are slow and not scalable, but Buck is fast and scales to huge projects that are built from source.
