使用Bazel构建外部Rust依赖时serde1特性失效问题求助

我尝试将Foundry作为外部依赖纳入仓库，需要用到其github.com/foundry-rs/foundry/blob/master/crates/cli中的forge CLI命令。

已配置WORKSPACE文件引入相关CLI crate及依赖：

crates_repository(
    name = "foundry",
    annotations = {
        "svm-rs": [crate.annotation(
            gen_binaries = True,
        )],
        "foundry-cli": [crate.annotation(
            gen_binaries = True,
        )],
        "forge": [crate.annotation(
            gen_binaries = True,
        )],
        "serde": [crate.annotation(
            gen_binaries = True,
        )],
    },
    cargo_lockfile = "//:Cargo.lock",
    lockfile = "//:Cargo.Bazel.lock",
    packages = {
        "svm-rs": crate.spec(
            git = "https://github.com/alloy-rs/svm-rs",
            rev = "b55c47b09437cf8dc01e1028aa0ab0a2300083d4",
        ),
        "forge": crate.spec(
            git = "https://github.com/foundry-rs/foundry",
            rev = "d5db2c514fea76291715b019db65b60aa41eb421",
        ),
        "foundry-cli": crate.spec(
            git = "https://github.com/foundry-rs/foundry",
            rev = "d5db2c514fea76291715b019db65b60aa41eb421",
        ),
        "serde": crate.spec(
            version = "1",
            features = ["derive"],
        ),
        #### Added the below while debugging
        "camino": crate.spec(
            version = "1.1.6",
            features = ["serde1"],
        ),
        "globset": crate.spec(
            version = "0.4.9",
            features = ["serde1"],
        ),
        "serde_derive": crate.spec(
            version = "1",
        ),
        "serde_json": crate.spec(
            version = "1",
        ),
        "hex": crate.spec(
            features = ["serde"],
        ),
        ### end of added
    },
)

之后我修改了生成的规则文件.cache/bazel/_bazel_j/6c68e123d5be80edfb5e3a8f56f57687/external/foundry__svm-rs-0.3.0/BUILD.bazel，把：

rust_binary(
    name = "svm__bin",
    ...

改为：

rust_binary(
    name = "svm",
    ...

执行命令bazel build @foundry//:foundry-cli__forge时出现以下错误：

根据serde文档，Deserialize和DeserializeSeed都属于serde1特性，但我已配置该特性，请问遗漏了什么？

问题出在Bazel编译proc-macro时的沙箱路径问题，以及依赖特性的传递性配置上，按以下步骤修复：

1. 替换手动修改BUILD文件的操作
   手动修改生成的BUILD文件会导致依赖图不一致，后续规则更新时还会被覆盖。直接在crates_repository的annotations中给svm-rs指定二进制名称：

   "svm-rs": [crate.annotation(
       gen_binaries = True,
       binary_name = "svm",
   )],
   

   这样生成的规则会直接使用svm作为二进制目标名，无需手动修改文件。

2. 修复serde_derive的proc-macro沙箱问题
   错误提示serde_derive的manifest文件找不到，是因为Bazel沙箱中proc-macro无法正确访问路径。给serde_derive添加注解，确保Bazel正确处理其构建脚本：
   在annotations中新增：

   "serde_derive": [crate.annotation(
       gen_build_script = True,
   )],
   

3. 确保serde特性的正确传递
   把serde_derive的依赖合并到serde的spec中，避免单独声明导致的版本不一致，同时保证特性传递正确：
   修改serde的配置：

   "serde": crate.spec(
       version = "1",
       features = ["derive"],
       dependencies = {
           "serde_derive": crate.spec(version = "1"),
       },
   ),
   

   然后删除单独的serde_derive条目。

4. 清理缓存并重新生成规则
   执行以下命令清理旧缓存，重新生成依赖规则：

   bazel clean --expunge
   bazel run @rules_rust//crate_universe:generate -- --config //:Cargo.Bazel.lock
   

5. 重新编译验证
   再次执行编译命令：

   bazel build @foundry//:foundry-cli__forge
