java - bazel run 有效，但构建部署 JAR 由于缺少依赖项而失败

Question

这里是 Java/Bazel 菜鸟。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.

似乎有些依赖项没有被可部署的 JAR 拾取，但在我运行 bazel run 时却被拾取。

这是我的(截断的)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",
    ],
)

摸索一下，我认为这可能与我的应用程序依赖的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？

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

我能够在这里获得一个与rules_jvm_external一起使用的“hello world”SpringBoot应用程序:https://github.com/thundergolfer/the-one-true-bazel-monorepo/commits/jonathon/spring-boot-backend

我在这里发布了有关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
