java - Gradle 平台与 java 库的依赖关系

Question

我们有几个公共(public)库，它们使用 java-library Gradle 插件，并通过平台依赖于 Micronaut 的 BOM 依赖于 Micronaut。这两个项目都使用 Gradle 6.6.1，这是撰写本文时的最新版本。

库 build.gradle

plugins {
    id "java-library"
}

repositories {
    mavenLocal()
    mavenCentral()
}

dependencies {

    annotationProcessor (
        platform("io.micronaut:micronaut-bom:$micronautVersion"),
        "io.micronaut:micronaut-inject-java"
    )

    implementation(
        platform("io.micronaut:micronaut-bom:$micronautVersion"),
        "io.micronaut:micronaut-inject"
    )

    testAnnotationProcessor(
        enforcedPlatform("io.micronaut:micronaut-bom:$micronautVersion"),
        "io.micronaut:micronaut-inject-java"
    )

    testImplementation(
        enforcedPlatform("io.micronaut:micronaut-bom:$micronautVersion"),
        "io.micronaut:micronaut-runtime",
        "io.micronaut:micronaut-http-server-netty",
        "io.micronaut:micronaut-http-client"
    )
}

当我尝试在应用程序中使用我的库时，该应用程序使用应用程序 Gradle 插件并且还对 Micronaut 的 BOM 具有平台依赖性，我收到一条错误消息，指出它无法解析库使用的 Micronaut BOM。但它永远无法解决该依赖关系，因为它是 BOM，而不是库。

应用build.gradle

plugins {
    id "application"
    id "java"
}

repositories {
    mavenLocal()
    mavenCentral()
}

dependencies {
    implementation(
        "my.group:library:${libraryVersion}",
    
        platform("io.micronaut:micronaut-bom:${micronautVersion}"),
        "io.micronaut:micronaut-http-client",
        "io.micronaut:micronaut-http-server-netty",
        "io.micronaut:micronaut-inject",
        "io.micronaut:micronaut-management",
        "io.micronaut:micronaut-runtime",
        "io.micronaut:micronaut-validation"
    )
}

然后我得到以下错误。

Caused by: org.gradle.internal.resolve.ModuleVersionResolveException: Could not resolve io.micronaut:micronaut-bom:2.0.1.
Required by:
    project : > my.group:library:11.0.0-SNAPSHOT
Caused by: org.gradle.internal.component.NoMatchingConfigurationSelectionException: No matching variant of io.micronaut:micronaut-bom:2.0.1 was found. The consumer was configured to find a runtime of a library compatible with Java 14, packaged as a jar, and its dependencies declared externally but:
  - Variant 'apiElements' capability io.micronaut:micronaut-bom:2.0.1:
      - Incompatible because this component declares an API of a platform and the consumer needed a runtime of a library
      - Other compatible attributes:
          - Doesn't say anything about how its dependencies are found (required its dependencies declared externally)
          - Doesn't say anything about its target Java version (required compatibility with Java 14)
          - Doesn't say anything about its elements (required them packaged as a jar)

我已经尝试阅读有关变体选择的 Gradle 文档，但它对我来说真的没有多大意义。任何人都知道我需要如何声明依赖项才能使它工作？这似乎是一件非常微不足道的事情，但我还没有找到任何关于这个的东西......

Answer 1

我正在使用 Gradle v7.4 并且能够通过将其添加到我的 build.gradle 来解决问题:

java {
  disableAutoTargetJvm()
}

我在 Upgrading Gradle version 5.x to 6.0 notes 中找到了答案.
