Gradle script that generates a task to copy all build variant's dependencies to a certain directory for use with Nexus IQ Server. It copies exploded AARs too, renaming the classes.jar file into "<aar_dependency_name>.jar".

copyDeps.gradle

apply plugin: 'com.android.application'

android.applicationVariants.all { variant ->
    task "copyDependencies${variant.name.capitalize()}"() {
        outputs.upToDateWhen { false }
        doLast {
            println "Executing copyDependencies${variant.name.capitalize()}"
            variant.getCompileClasspath().each { fileDependency ->
                def sourcePath = fileDependency.absolutePath
                def destinationPath = project.projectDir.path + "/build/dependencies/${variant.name}/"
                println "Copying dependency:"
                println sourcePath

//The monstrous regex that gets the name of the lib from it’s exploded .aar path
                def dependencyName
                if (sourcePath.contains("classes.jar")) {
                    def dependencyNameRegexResult = (sourcePath =~ /.*\/(.*)\.aar\/.*\/jars\/classes\.jar/)
                    if (dependencyNameRegexResult.size() > 0) {
                        dependencyName = dependencyNameRegexResult[0][1]
                        println "Exploded AAR found : ${dependencyName}"
                    }
                }

                copy {
                    from sourcePath
                    into destinationPath

                    rename {String filename ->
                        if (filename.contains("classes.jar") && dependencyName != null) {
                            dependencyName = "${dependencyName}.jar"
                            println "Renaming dependency file to : ${dependencyName}"
                            return dependencyName
                        }
                        return filename
                    }
                }
            }
        }
    }
}

if you just want to list all dependencies with their versions for a configuration

thanks for your script. but i wonder how to get the dependencies in my custom AS plugin. Is there any gradle APIs for Idea Plugin developing? i have googled a lot but got nothing i want. Hope you can help me.

@git4pl sorry, can't help you bud. Maybe you could look for a Slack community of JetBrains or Gradle - there should be people who can help you. I also couldn't find any documentation on the implemented methods of AS Gradle Plugin.
