**WORKSPACE setup**

With Bazel 8.0.0 and before 8.3.0, add the following to your `.bazelrc` file:

~~~
# https://github.com/bazelbuild/bazel/pull/26119
common --repositories_without_autoloads=bazel_features_version,bazel_features_globals
~~~

In all cases, add the following to your `WORKSPACE` file:

~~~
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
    name = "rules_java",
    urls = [
        "https://github.com/bazelbuild/rules_java/releases/download/{VERSION}/rules_java-{VERSION}.tar.gz",
    ],
    sha256 = "$$sha",
)

load("@rules_java//java:rules_java_deps.bzl", "rules_java_dependencies")
rules_java_dependencies()

load("@bazel_features//:deps.bzl", "bazel_features_deps")
bazel_features_deps()

# note that the following line is what is minimally required from protobuf for the java rules
# consider using the protobuf_deps() public API from @com_google_protobuf//:protobuf_deps.bzl
load("@com_google_protobuf//bazel/private:proto_bazel_features.bzl", "proto_bazel_features")  # buildifier: disable=bzl-visibility
proto_bazel_features(name = "proto_bazel_features")

# register toolchains
