bazel run 有效，但由于缺少依赖项，构建部署 JAR 失败

Question

这里是 Java/Bazel 新手。我有一个使用 Spring Boot 的项目（并使用 rules_jvm_external 管理外部依赖项）。

我能够成功运行 bazel run，但是当我尝试构建 _deploy.jar 时，应用程序失败并出现以下错误：

11:48:11.913 [main] ERROR org.springframework.boot.SpringApplication - Application run failed
org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.context.ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean.

似乎某些依赖项没有被可部署 JAR 拾取，但在我运行 bazel run 时被拾取。

这是我的（截断的）BUILD 文件：

filegroup(
    name = "java_files",
    srcs = glob(["src/main/java/**/*.java"]),
)
filegroup(
    name = "java_test_files",
    srcs = glob(["src/test/java/com/**/*.java"]),
)
java_library(
    name = "lib",
    srcs = [
        ":java_files",
    ],
    resources = glob(["src/main/resources/**"]),
    deps = [
        # Plugins and internal dependencies

java_binary(

    name = "app",
    main_class = "com.my.org.Application",
    runtime_deps = [
        ":lib",
    ],
)

在黑暗中猛烈抨击，我认为这可能与我的应用程序所依赖的 Java 插件有关，但我不确定为什么这会导致 Spring Boot 无法启动。有人知道会发生什么吗？

你试过https://github.com/salesforce/bazel-springboot-rule/吗？

我能够在此处获得一个带有 rules_jvm_external 的“hello world”SpringBoot 应用程序：https://github.com/thundergolfer/the-one-true-bazel-monorepo/commits/jonathon/spring-boot-backend

我在这里发布了关于 rules_jvm_external 与 github.com/salesforce/bazel-springboot-rule 兼容性的问题：https://github.com/salesforce/bazel-springboot-rule/issues
