Bazel 映射目录位于 `src` 到 `build` 之外

Question

我不知道 Bazel 或者它是如何工作的，但我必须解决这个问题，最终归结为 bazel 没有将某个目录复制到 build.gradle 中。
我重构了一个代码，因此首先尝试从目录 private-keys 中读取某个键( jwk ) .运行时总是找不到文件。我认为 bazel 没有复制 private-keys目录(与 src 处于同一级别)到 build .

Project/
|-- private-keys\
|-- src/
|   |-- //other directories
|   |-- index.ts
|
|-- package.json
|-- BUILD.bazel

src里面有复制目录的映射对象我尝试使用 ../private-keys那里但没有工作。
以下是如何 BUILD.bazel好像

SOURCES = glob(
    ["src/**/*.ts"],
    exclude = [
        "src/**/*.spec.ts",
        "src/__mocks__/**/*.ts",
    ],
)

mappings_dict = {
    "api": "build/api",
    ....
}

ts_project(
    name = "compile_ts",
    srcs = SOURCES,
    incremental = True,
    out_dir = "build",
    root_dir = "src",
    tsc = "@npm//typescript/bin:tsc",
    tsconfig = ":ts_config_build",
    deps = DEPENDENCIES + TYPE_DEPENDENCIES,
)

ts_project(
    name = "compile_ts",
    srcs = SOURCES,
    incremental = True,
    out_dir = "build",
    root_dir = "src",
    tsc = "@npm//typescript/bin:tsc",
    tsconfig = ":ts_config_build",
    deps = DEPENDENCIES + TYPE_DEPENDENCIES,
)

_mappings = module_mappings(
    name = "mappings",
    mappings = mappings_dict,
)

# Application binary and docker imaage
nodejs_image(
    name = "my-service",
    data = [
        ":compile_ts",
        "@npm//source-map-support",
    ] + _mappings,
    entry_point = "build/index.js",
    templated_args = [
        "--node_options=--require=source-map-support/register",
        "--bazel_patch_module_resolver",
    ],
)

构建目标的命令始终在单独的目录中运行。要告诉 Bazel 它需要复制一些额外的文件，您需要将这些文件包装在 filegroup 中。目标(参见 bazel docs)。
然后将此类文件组目标添加到 deps目标的属性。(参见示例 here)。
在你的情况下，它会是这样的

filegroup(
  name = "private_keys",
  srcs = glob(["private_keys/**"]),
)

ts_project(
    name = "compile_ts",
    srcs = SOURCES,
    data = [ ":private_keys" ], # <-- !!!
    incremental = True,
    out_dir = "build",
    root_dir = "src",
    tsc = "@npm//typescript/bin:tsc",
    tsconfig = ":ts_config_build",
    deps = DEPENDENCIES + TYPE_DEPENDENCIES,
)

您也可以插入 glob(...)直接进入 data属性但是，将其设置为文件组使其可重用......并使您看起来像专业人士。 :)
