java - Android ライブラリ .jar (.aar ではない) を JCenter に公開する

Question

このチュートリアルを使用して、小さなライブラリを jcenter に公開しました。

https://github.com/danielemaddaluno/gradle-jcenter-publish

ただし、他のプロジェクトの依存関係に追加すると、ライブラリから javadoc がプルされないことが判明しました。グーグルで調べたところ、その理由は .aar - パッケージングのようです。ライブラリにはリソースが含まれておらず、ソースコードのみが含まれているため、.jar としてパッケージ化できると思います。そのためには、gradle スクリプトをどのように変更すればよいですか? 前もって感謝します。

私が使用したbuild.gradleの例：

apply plugin: 'com.android.library'
apply plugin: 'com.github.dcendents.android-maven'
apply plugin: "com.jfrog.bintray"

// This is the library version used when deploying the artifact
version = "1.0.0"

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        //applicationId "com.madx.updatechecker.lib"
        minSdkVersion 8
        targetSdkVersion 21
        versionCode 1
        versionName "1.0.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'org.jsoup:jsoup:1.8.1'
