See https://github.com/Bit-Quill/arrow/pull/1 to get the build (though not the tests) passing

[lidavidm]

Looks like this still doesn't build, I'll take another look soon

[lidavidm]

Hmm, well, it builds locally, though it fails with a different error…and I can't replicate the CI. Seeing what happens with my fork's CI here: https://github.com/lidavidm/arrow/tree/flight-sql-jdbc

Otherwise I might ask that we just rebase this and see if it bumps whatever might be causing this

[lidavidm]

Ok, I'm dumb - it's because the version number got updated again. I'll put up another PR to fix that and the compilation failures. I also think there'll be some test failures.

@jduo see https://github.com/Bit-Quill/arrow/pull/5

[lidavidm]

Great, CI looks good now (minus known extant issues). I'll give this a final review soon

[lidavidm]

CI failures are unrelated/addressed elsewhere

Awesome news! Thank you very much for all the hard work that went into this. My company is very excited to make some PRs in the near future :)
