# NB: the `:all` here is critical, because `proto_lang_toolchain` expands into two targets:
# - proto_lang_toolchain rule [name]
# - toolchain rule [name]_toolchain
# and the second one is valid for registration.
# Attempting to register a proto_lang_toolchain rule as a toolchain gives a baffling error like
# Misconfigured toolchains: //tools:protoc_java_toolchain is declared as a toolchain but has inappropriate dependencies.
# Declared toolchains should be created with the 'toolchain' rule and should not have dependencies that themselves require toolchains.

# Note: this is simpler than using rules_jvm_external with a maven installation,

#     artifacts = [

#         "io.grpc:grpc-all:1.51.1",
