After performing the build, to run the converter using compute.v1.json as a sample input (included in this repository) run the following command from the repository root:

Check the google/cloud/compute/v1 directory for the converted compute.proto file.

The converter can also be used from Bazel via the proto_from_disco bazel rule like the following:

load(

    "proto_from_disco",
)

proto_from_disco(
    name = "compute",
    src = "//:src/test/resources/compute.v1.json",
)
