爲什麼Gradle不能在我的Android模塊依賴關係中使用？

Question

所以我試圖在IntelliJ IDEA中使用Gradle首次創建一個多模塊項目。我花了一個小時閱讀文檔和各種教程和SO問題，卻無法解決這個簡單的問題。我的結構：

-Project 
    |-vg 
    |-vgcommon 

vgcommon是一個Android搖籃模塊，而vg是一個Android搖籃應用（技術上也是一個模塊）。

• vg取決於vgcommon
• vgcommon建立
• vg沒有，因爲所有從vgcommon類是 「未找到」。

這是我的gradle.build文件和setup.gradle。任何人都可以看到我做錯了什麼？

settings.gradle（根級別）

include ':vgcommon', ':VG' 

vgcommon \的build.gradle

buildscript { 
    repositories { 
     mavenCentral() 
     maven { url 'http://download.crashlytics.com/maven' }

     classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1+' 
    }

Answer 1

的vgcommon模塊定義爲應用模塊，而不是一個庫。在其的build.gradle，而不是這一行：

apply plugin: 'android' 

使用本：

apply plugin: 'android-library'
