一、dependencies 依赖查找路径

---

android 工程中 , 配置的 依赖 , 有 $2$ 种查找依赖包的方式 ,

• 方式一 : 到根目录中配置的 google , mavenCentral , jcenter 远程仓库中查找依赖库 ;

allprojects 
    repositories 
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
    

• 方式二 : 到 SDK 目录中的本地仓库查找 , 其路径是 SDK\\extras\\android\\m2repository , 如下图 :

在我的电脑的 SDK\\extras\\android\\m2repository\\com\\android\\support 路径中 , 就是依赖中常用的支持库 :

二、dependencies 依赖冲突问题

---

添加构建依赖项 参考文档 : https://developer.android.google.cn/studio/build/dependencies

如果在 build.gradle 的 dependencies 依赖配置中 , 配置如下依赖库 :

dependencies 
	implementation 'com.facebook.fresco:fresco:0.14.0'
	implementation 'com.Android.support:appcompat-v7:23.0.0'

执行

gradlew :app:assembleDebug

命令 , 进行编译打包时 ;

在编译打包时 , 就会出现依赖冲突问题 ,

appcompat-v7 函数库依赖了 appcompat-v4 函数库 ,

fresco 函数库也同样依赖了 appcompat-v4 函数库 ,

这样就使得应用同时导入了 $2$ 个 appcompat-v4 函数库 ;

在上一篇博客 【Android Gradle 插件】Gradle 依赖管理 ⑤ ( dependencies 依赖项拆分 | 依赖组 | 依赖名称 | 依赖版本号 | 动态指定依赖版本号 | 使用命令行查看模块 ) 中介绍了如果配置了两个相同的依赖 , 则选取较高版本的依赖库 ,

因此原理上 , 不会出现依赖冲突问题 ;

三、dependencies 依赖库层级分析

---

分析依赖问题 , 就需要查看依赖情况 , 在 Terminal 面板中执行

gradlew :app:dependencies

命令 , 查看依赖的情况 , 逐个排查依赖冲突问题 ;

在输出日志中 , 可以查看顶层依赖库 , 与依赖库的依赖库之间的依赖关系 ;

com.android.support.constraint:constraint-layout:2.0.1 是顶层依赖库 ,

+--- com.android.support.constraint:constraint-layout:2.0.1

该依赖库又依赖了 com.android.support:appcompat-v7:28.0.0 依赖库 ,

+--- com.android.support.constraint:constraint-layout:2.0.1
|    +--- com.android.support:appcompat-v7:28.0.0

com.android.support:appcompat-v7:28.0.0 依赖库 又依赖了 com.android.support:support-annotations:28.0.0 com.android.support:support-compat:28.0.0 等依赖库 ;

+--- com.android.support.constraint:constraint-layout:2.0.1
|    +--- com.android.support:appcompat-v7:28.0.0
|    |    +--- com.android.support:support-annotations:28.0.0
|    |    +--- com.android.support:support-compat:28.0.0

完整的依赖库层级如下 :

debugCompileClasspath - Resolved configuration for compilation for variant: debug
+--- com.android.support.constraint:constraint-layout:2.0.1
|    +--- com.android.support:appcompat-v7:28.0.0
