【问题描述】：

特使：v1.7.0 以下规则

load("@envoy//bazel:repositories.bzl", "envoy_dependencies")
envoy_dependencies(repository="@envoy", skip_targets=["io_bazel_rules_go"])
local_repository(
    name = "io_bazel_rules_go",
    path = "/root/io_bazel_rules_go",
)

给我错误：

ERROR: xxx/WORKSPACE:47:1: unexpected keyword 'repository' in call to envoy_dependencies(path = "@envoy_deps//", skip_targets = [])
ERROR: Error evaluating WORKSPACE file
ERROR: error loading package '': Encountered error while reading extension file 'bazel/repositories.bzl': no such package '@envoy_api//bazel': error loading package 'external': Could not load //external package
ERROR: error loading package '': Encountered error while reading extension file 'bazel/repositories.bzl': no such package '@envoy_api//bazel': error loading package 'external': Could not load //external package
INFO: Elapsed time: 6.944s

FAILED: Build did NOT complete successfully (0 packages loaded)

任何关于如何跳过构建 io_bazel_rules_go 的信息都会很有用。

第一条错误信息是相关的，其他的可以忽略：

ERROR: xxx/WORKSPACE:47:1: unexpected keyword 'repository' in call to envoy_dependencies(path = "@envoy_deps//", skip_targets = [])

这告诉我们envoy_dependencies 没有名为repository 的属性，而签名显示有path。

您可以在规则的实现中自己检查：https://github.com/envoyproxy/envoy/blob/3f59fb5c0f6554f8b3f2e73ab4c1437a63d42668/bazel/repositories.bzl#L182

是的.. 年长的特使有这个选项，但现在没有。仍然如何跳过io_bazel_rules_go 的分叉和构建并告诉它使用我在主机中已经拥有的存储库。
