Of the three, only two are Google produced. The rust implementation is written by Facebook for use in their build system. The java implementation is the original but is pretty tied to the the bazel build system and not really very suitable to other uses. The go implementation is meant to be embeddable into a varying number of applications.

An example application is https://github.com/shac-project/shac

Within Google, there a large number of similar tools which are written in go and harness the starlark language. While there are plenty of other options, I will say I think starlark is often a great choice.
