Bazel 如何组织第三方java_库规则？

我有许多

BUILD

文件需要Jetty或其他常见Java库（SLF4J、Lucene、Guava等）。其中每一个都有一组它引用的其他jar。我想知道在大型项目中组织这些声明及其依赖关系的最佳实践

例如，使用

generate_workspace

via

bazel run//src/tools/generate_workspace--artifact=org.eclipse.jetty:jetty server:9.3.8.v20160314

# The following dependencies were calculated from:
# org.eclipse.jetty:jetty-server:9.3.8.v20160314


java_library(
    name = "org_eclipse_jetty_jetty_http",
    visibility = ["//visibility:public"],
    exports = [
        "@org_eclipse_jetty_jetty_http//jar",
        "@org_eclipse_jetty_jetty_util//jar",
    ],
)

java_library(
    name = "org_eclipse_jetty_jetty_util",
    visibility = ["//visibility:public"],
    exports = [
        "@org_eclipse_jetty_jetty_util//jar",
    ],
)

java_library(
    name = "javax_servlet_javax_servlet_api",
    visibility = ["//visibility:public"],
    exports = [
        "@javax_servlet_javax_servlet_api//jar",
    ],
)

java_library(
    name = "org_eclipse_jetty_jetty_server",
    visibility = ["//visibility:public"],
    exports = [
        "@org_eclipse_jetty_jetty_server//jar",
        "@javax_servlet_javax_servlet_api//jar",
        "@org_eclipse_jetty_jetty_http//jar",
        "@org_eclipse_jetty_jetty_io//jar",
        "@org_eclipse_jetty_jetty_util//jar",
    ],
)

java_library(
    name = "org_eclipse_jetty_jetty_io",
    visibility = ["//visibility:public"],
    exports = [
        "@org_eclipse_jetty_jetty_io//jar",
        "@org_eclipse_jetty_jetty_util//jar",
    ],
)

和

我在许多项目中都依赖jetty server和jetty util。有没有比在每个

构建

文件中重复此信息更好的做法？

通常，您会将

生成的构建文件

放在工作区的根目录中（工作区文件旁边），然后在其他构建文件中，您会引用它们需要依赖的任何目标。例如，在src/main/java/com/your project/subcomponent/BUILD中，您可能会说：

java_library(
    name = "my-servlet",
    srcs = glob(["*.java"]),
    deps = [
        "//:javax_servlet_javax_servlet_api",
        # other deps...
    ],
)
