Android Gradle在另一个模块中包含模块依赖项 [英] Android Gradle include module dependencies in another module

问题描述

我正在使用最新的Android Studio 3.0.0-beta6来构建我的Android项目，并且存在此依赖项问题. Gradle鼓励我将所有compile's替换为implementation's.这是我的项目结构:

I am using the latest Android Studio 3.0.0-beta6 to build my Android project and there's this dependency issue. Gradle encouraged me to replace all compile's with implementation's. Here's my project structure:

项目:

• module1

• module1

• module2

Module1依赖于某些库，module2依赖于module1.但是，来自module1的库在module2中不可见.我不想复制粘贴依赖项，而是只将库依赖项声明一次.有一个简单的解决方案吗?谢谢.

Module1 depends on some libraries, module2 depends on module1. However, the libraries from module1 are not visible in module2. I don't want to copy-paste dependencies and would rather have the library dependencies declared only once. Is there a simple solution to this? Thank you.

module1的构建包:

module1's build gradle:

dependencies {
    ....
    implementation 'io.reactivex.rxjava2:rxandroid:2.0.1'
    implementation 'com.squareup.retrofit2:adapter-rxjava2:2.3.0'
    ...
}

module2的构建包:

module2's build gradle:

implementation project(':module1')

推荐答案

在您的Root Project中-> build.gradle，您应该具有以下内容:

In your Root Project -> build.gradle you should have something like:

allprojects {
    repositories {
        jcenter()
    }
}

在此处添加依赖项！

更新

如果您不希望所有模块都具有公共依赖性，而只希望特定模块，那么请执行以下操作:

If you do not want all your modules to have the common dependencies but only specific modules then do this:

1. 在您的Root Project/gradleScript中创建一个文件夹

2. 在此文件夹中创建一个.gradle文件(例如gradleScript/dependencies.gradle) 看起来像这样:

1. Create a folder in your Root Project/gradleScript

2. Create a .gradle file in this folder (e.g. gradleScript/dependencies.gradle) that looks like:

ext {

//Version

supportLibrary = '22.2.1'

//Support Libraries dependencies
supportDependencies = [
        design           :         "com.android.support:design:${supportLibrary}",
        recyclerView     :         "com.android.support:recyclerview-v7:${supportLibrary}",
        cardView         :         "com.android.support:cardview-v7:${supportLibrary}",
        appCompat        :         "com.android.support:appcompat-v7:${supportLibrary}",
        supportAnnotation:         "com.android.support:support-annotations:${supportLibrary}",
]
}

在您的根项目build.gradle中添加以下行:

In your root project build.gradle add this line:

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.2.3'
}
}

// Load dependencies
apply from: 'gradleScript/dependencies.gradle'

在您的模块中相应地添加以下内容:

In your modules accordingly add this:

// Module build file

dependencies {
    //......
    compile supportDependencies.appCompat
    compile supportDependencies.design
}

希望这会有所帮助！
