Problem identified after some more searching with different errors than previously. Buck needs JDK8. Later have some features it uses removed.

Buck calls buck to build it (or I guess check if it's running?) this means it can't be built on machines that don't have a buck command already.

Fixed dependencies.

This package fails to build in a clean chroot with devtools since it apparently requires Java 8 to build but this dependency is not expressed properly in makedepends, causing pacman’s automatic selection to install a different version. Additionally, python is apparently also needed at buildtime (without it I get a build failure with error /build/buck/src/buck-2018.06.25.01/build.xml:889: Execute failed: java.io.IOException: Cannot run program "python" (in directory "/build/buck/src/buck-2018.06.25.01"): error=2, No such file or directory).

I added a prepare function to detect java version.

Indeed, just figured it out myself.

I have no idea what went so horribly wrong, but it seems like it doesn't like even totally 101 Java stuff.

Been some years since I did Java, any ideas on how to fix this?

Hmm, that seems not right. I'll take a look at that as soon as I get a chance.

I have the option set in makepkg.conf to build packages in /tmp/makepkg, which causes prepare() to fail to find python-test-output.patch. Since makepkg makes symlinks of sources to ${srcdir}, the following patch fixed the build for me:
