从Spring-dependency-management插件中提取依赖版本

Question

我有一个Gradle Task来从项目中提取依赖项并使用该数据。下面是我的Gradle Task

task gavValidation() {

    doLast {
        project(':app').configurations.each { 
            configurationType ->
            println "configurationType >>> "+configurationType.name
            configurationType.allDependencies.each {
                gav ->
                println gav.group+" : "+gav.name+" : "+gav.version
            }
        }
    }

}

当print打印null时，gav.version声明总是来自Spring Dependency Management。

我发现，这些依赖项的版本在

apply plugin: 'io.spring.dependency-management'
    dependencyManagement {
        imports {
            mavenBom 'org.springframework.cloud:spring-cloud-dependencies:Edgware.RELEASE'
            mavenBom 'io.pivotal.spring.cloud:spring-cloud-services-dependencies:1.5.0.RELEASE'
            mavenBom 'org.springframework.boot:spring-boot-dependencies:1.5.13.RELEASE'

        }
        dependencies {
            dependency 'io.springfox:springfox-swagger2:2.8.0'
            dependency 'io.springfox:springfox-swagger-ui:2.8.0'

        }
    }

插件中维护。以下是片段

如何在我的自定义任务中获取该版本？目前为空

Answer 1

正如在Configuration.getDependencies()中所解释的那样，方法Configuration.getAllDependencies()或Configuration.getResolvedConfiguration()只返回声明的依赖项，并且不会触发依赖项解析。因此，对于来自Spring BOM的依赖项，该版本尚不为人所知。

您可以使用

task gavValidation() {
    doLast {
        configurations.each { configurationType ->
            println " ***************** configurationType >>> " + configurationType.name
            if (configurationType.canBeResolved) {
                configurationType.getResolvedConfiguration().getResolvedArtifacts().each { artefact ->
                    ModuleVersionIdentifier id = artefact.getModuleVersion().getId()
                    println id.group + " : " + id.name + " : " + id.version
                }
            }
        }
    }
}

方法，如下所示：
