Update version of pex in buck

[kageiit]

The current version in the buck repo is from Nov 2015. We are ubale to build some pex due to this being so out of date. Can this be upgraded? There are a lot of modifications from the fb maintainers around the base pex codebase. We would be happy to take a look if someone can point us the right way in what to keep etc.

There isn't a plan to upgrade to Python3. However, if you'd like to contribute and keep it compatible with both Python 2 and 3, please feel free to submit a PR. Thanks.

Is there any way to launch buck from the jar file directly? In this way, buck doesn't even need to depend on Python.

There is a way to run Buck without building a pex file, but this way still requires Python.

You can build buck using ant: ant clean default and then run it using bin/buck.

In this case, the python requirement is only for Python scripting support in the BUCK file?
