Android庫 - 使用Gradle將多個變體發佈到本地Maven存儲庫

Question

我正在使用Android Gradle插件0.13.2，Android Studio 0.8.11，Gradle 2.1和maven插件。

我想用一個命令（任務）將我的Android庫的多個變體（flavor + build type）安裝到本地Maven倉庫中。

目前Android的搖籃插件0.13.2讓我publishNonDefault標誌設置爲發佈的所有變化，但隨着文檔指出，將出版的變異與分類這是不符合Maven倉庫兼容。

我現在的解決方法是使用defaultPublishConfig「myVariant」並對每個變體進行更改。

apply plugin: 'com.android.library' 
apply plugin: 'maven' 

android { 
    defaultPublishConfig "myVariant" 
    . 
    . 
    . 

} 

task installArchives(type: Upload) { 
    repositories.mavenInstaller { 
     configuration = configurations.getByName(Dependency.DEFAULT_CONFIGURATION) 
     pom.groupId = "com.company" 
     pom.artifactId = "mylibrary" 
     pom.version = "1.0.0-myVariant" 
    } 
} 

我想要有一個任務能夠將所有變體正確地發佈到本地Maven存儲庫。

爲了解決這個問題，我必須爲每個變體創建一個上傳任務，並使它們彼此依賴並依賴於啓動該過程的主任務。

apply plugin: 'com.android.library' 
apply plugin: 'maven' 

android { 
    . 
    . 
    . 

} 

// Master task that will publish all variants 
def DefaultTask masterTask = project.tasks.create("installArchives", DefaultTask) 

android.libraryVariants.all { variant -> 
    variant.outputs.each { output -> 

     // Configuration defines which artifacts will be published, create one configuration for each variant output (artifact) 
     def Configuration variantConfiguration = project.configurations.create("${variant.name}Archives") 
     project.artifacts.add(variantConfiguration.name, output.packageLibrary) 

     // Create one Upload type task for each configuration 
     def Upload variantTask = project.tasks.create("${variant.name}Install", Upload) 
     variantTask.configuration = variantConfiguration 
     variantTask.repositories.mavenInstaller { 
      pom.groupId = "com.yourcompany" 
      pom.artifactId = "yourLibrary" 
      pom.version = "1.0.0-${variant.name}" //Give a different version for each variant 
      pom.packaging = "aar" 
     } 

     // Make all tasks depend on each other and on master task 
     masterTask.dependsOn variantTask 
     masterTask = variantTask 
    } 
} 

任務installArchives將發佈到本地Maven倉庫所有變體。

./gradlew installArchives
