一、dependencies 依赖查找路径
Android 工程中 , 配置的 依赖 , 有 %22%20aria-hidden%3D%22true%22%3E%0A%20%3Cuse%20xlink%3Ahref%3D%22%23E1-MJMAIN-32%22%20x%3D%220%22%20y%3D%220%22%3E%3C%2Fuse%3E%0A%3C%2Fg%3E%0A%3C%2Fsvg%3E)
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 %22%20aria-hidden%3D%22true%22%3E%0A%20%3Cuse%20xlink%3Ahref%3D%22%23E1-MJMAIN-32%22%20x%3D%220%22%20y%3D%220%22%3E%3C%2Fuse%3E%0A%3C%2Fg%3E%0A%3C%2Fsvg%3E)
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 :
