bazel运行正常，但由于缺少依赖项，构建deploy JAR失败

Question

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

我可以成功运行bazel run，但当我尝试构建_deploy.jar时，应用程序失败，并显示以下错误：

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.

似乎有些依赖项不是通过可部署的JAR获得的，而是在我运行bazel run时获得的。

下面是我的(截断)构建文件：

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
        "//build-utils/lombok",
        "//build-utils/mapstruct",

java_binary(
    # not the real names
    name = "app",
    main_class = "com.my.org.Application",
    runtime_deps = [
        ":lib",
    ],
)

试试看，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。有人知道可能会发生什么吗？

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

我可以在rules_jvm_external上安装一个“hello world”的SpringBoot应用程序：https://github.com/thundergolfer/the-one-true-bazel-monorepo/commits/jonathon/spring-boot-backend

我在这里发布了一个关于rules_jvm_external与github.com/salesforce/bazel-springboot-rule的兼容性的问题：https://github.com/salesforce/bazel-springboot-rule/issues
