使用Gradle 5.1的“实现平台"，可以使用“代替Spring Dependency Management插件 [英] Using Gradle 5.1 "implementation platform" instead of Spring Dependency Management Plugin

问题描述

我写了一个Gradle插件，其中包含许多常用的设置配置，因此我们所有的项目都只需要应用该插件和一组依赖项即可.它使用Spring Dependency Management插件为Spring设置BOM导入，如下面的代码片段所示:

I have written a Gradle Plugin that contains a bunch of common setup configuration so that all of our projects just need to apply that plugin and a set of dependencies. It uses the Spring Dependency Management Plugin to setup the BOM imports for Spring as shown in the code snippet below:

trait ConfigureDependencyManagement {
    void configureDependencyManagement(final Project project) {
        assert project != null

        project.apply(plugin: "io.spring.dependency-management")

        final DependencyManagementExtension dependencyManagementExtension = project.extensions.findByType(DependencyManagementExtension)
        dependencyManagementExtension.imports {                 
            mavenBom "org.springframework.boot:spring-boot-dependencies:2.1.0.RELEASE"
        }
     }
  }

虽然在Gradle 5.1中仍然可以使用，但我想用BOM导入的新依赖机制替换Spring Dependency Management插件，所以我将上面的内容更新为:

Whilst that still works in Gradle 5.1 I wanted to replace the Spring Dependency Management Plugin with the new dependency mechanism for BOM Imports so I updated the above to now be this:

trait ConfigureDependencyManagement {
    void configureDependencyManagement(final Project project) {
        assert project != null

        project.dependencies.platform("org.springframework.boot:spring-boot-dependencies:2.1.0.RELEASE")
    }
}

不幸的是，更改意味着没有导入由这些BOM表定义的依赖项，并且在构建项目时遇到了类似的错误?

Unfortunately that change means none of the dependencies defined by these BOMs are being imported and I get errors like these when building projects?

找不到org.springframework.boot:spring-boot-starter-web:. 要求者: 项目:

Could not find org.springframework.boot:spring-boot-starter-web:. Required by: project :

找不到org.springframework.boot:spring-boot-starter-data-jpa:. 要求者: 项目:

Could not find org.springframework.boot:spring-boot-starter-data-jpa:. Required by: project :

找不到org.springframework.boot:spring-boot-starter-security:. 要求者: 项目:

Could not find org.springframework.boot:spring-boot-starter-security:. Required by: project :

我是否正确地认为Gradle 5.1不再需要Spring Dependency Management插件?如果是的话，我是否缺少一些可以使之起作用的东西?

Am I correct in thinking the Spring Dependency Management Plugin is no longer needed with Gradle 5.1 and if so then am I missing something for this to work?

推荐答案

Gradle 5中的平台支持可以代替Spring依赖管理插件来消耗BOM.但是，Spring插件提供了Gradle支持未涵盖的功能.

The platform support in Gradle 5 can replace the Spring dependency management plugins for BOM consumption. However the Spring plugin offers features that are not covered by the Gradle support.

关于您的问题，问题来自以下行:

Regarding your issue, the problem comes from the following line:

project.dependencies.platform("org.springframework.boot:spring-boot-dependencies:2.1.0.RELEASE")

这只会创建一个Dependency，它仍然需要添加到配置中.通过执行类似的操作:

This will simply create a Dependency, it still needs to be added to a configuration. by doing something like:

def platform = project.dependencies.platform("org.springframework.boot:spring-boot-dependencies:2.1.0.RELEASE")
project.dependencies.add("configurationName", platform)

其中，configurationName是需要BOM的配置的名称.请注意，根据您的项目，您可能必须将此BOM添加到多种配置中.

where configurationName is the name of the configuration that requires the BOM. Note that you may have to add this BOM to multiple configurations, depending on your project.
