Pull Dependency version from Spring-dependency-management plugin

I have a Gradle Task to pull the dependencies from a project and play with that data. Below is my 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
            }
        }
    }

}

The print statement always come as null when it is printing gav.version above.

What i found is that, the versions of these dependencies are maintained in Spring Dependency Management Plugin. Below is the snippet

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'

        }
    }

How to get the version in my custom-task ? that is currently coming as null

As explained in Working with Dependencies , the methods Configuration.getDependencies() or Configuration.getAllDependencies() only return the declared dependencies and do not trigger dependency resolution. So for dependencies coming from Spring BOM, the version is not known yet.

You can use Configuration.getResolvedConfiguration() method instead, as follows:

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
                }
            }
        }
    }
}
