使用 gradle 无法为 aar 库解析传递依赖项 [英] Transitive dependencies not resolved for aar library using gradle

问题描述

我已经调查了一段时间，可能在这里看到了与 aar 和 传递依赖 相关的最流行的答案，但不知何故，我仍然不清楚如何使其工作.

I have investigated a while and probably saw most popular answers here related to aar and transitive dependencies but somehow it is still not clear for me how to make this working.

所以:

我有给定 gradle 配置的 android 库:

I have android library with given gradle config:

apply plugin: 'android-library'
apply plugin: 'android-maven'

version = "1.0.0"
group = "com.somepackage"

buildscript {
    repositories {
        mavenCentral()
        mavenLocal()
    }

    dependencies {
        classpath 'com.github.dcendents:android-maven-plugin:1.0'
    }
}

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.3'

    defaultConfig {
        minSdkVersion 10
    }
}

repositories {
    maven { url 'http://www.bugsense.com/gradle/' }
}

dependencies {
    provided 'com.google.android.gms:play-services:+'
    provided 'com.android.support:appcompat-v7:+'
    compile 'com.google.code.gson:gson:2.2.4'
    compile 'com.bugsense.trace:bugsense:3.6'
    compile 'commons-net:commons-net:3.3'
}

然后我使用 gradle install 将它部署到本地 maven 存储库.已部署库的 POM 文件如下所示:

Then I am deploying it to local maven repo with gradle install. POM file of the deployed library looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.sprezzat</groupId>
  <artifactId>app</artifactId>
  <version>1.0.0</version>
  <packaging>aar</packaging>
  <dependencies>
    <dependency>
      <groupId>com.bugsense.trace</groupId>
      <artifactId>bugsense</artifactId>
      <version>3.6</version>
      <scope>compile</scope>
    </dependency>
    <dependency>
      <groupId>commons-net</groupId>
      <artifactId>commons-net</artifactId>
      <version>3.3</version>
      <scope>compile</scope>
    </dependency>
    <dependency>
      <groupId>com.google.code.gson</groupId>
      <artifactId>gson</artifactId>
      <version>2.2.4</version>
      <scope>compile</scope>
    </dependency>
  </dependencies>
</project>

最后使用上述库作为依赖项对我的 android 应用程序进行 gradle 配置:

And finally gradle config of my android application using above library as a dependency:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.9.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
    mavenLocal()
}

android {
    compileSdkVersion 15
    buildToolsVersion "19.0.2"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 18
    }
}

dependencies {
    compile 'com.google.android.gms:play-services:+'
    compile 'com.android.support:appcompat-v7:+'
    compile 'com.somepackage:LIBRARY_NAME:1.0.0@aar'
}

在手机上部署应用程序后，我收到了属于我的 android 库的编译依赖项的类的 NoClassDefFoundError.

And after deploying application on phone I am getting NoClassDefFoundError for classes belonging to compile dependencies of my android library.

使用gradle dependencies检查我的android应用程序依赖:

Inspecting my android application dependencies using gradle dependencies:

apk - Classpath packaged with the compiled main classes.
+--- com.google.android.gms:play-services:+ -> 4.3.23
|    --- com.android.support:support-v4:19.0.1 -> 19.1.0
+--- com.android.support:appcompat-v7:+ -> 19.1.0
|    --- com.android.support:support-v4:19.1.0
--- com.somepackage:LIBRARY_NAME:1.0.0

根据上面的树，没有检测到所有的传递依赖.问题出在哪里，应该如何正确处理?

According to above tree, all transitive dependencies are not detected. Where is the problem and how should it be done correctly?

推荐答案

我通过为我的 aar 依赖项设置 transitive 属性解决了我的问题:

I have solved my problem by setting transitive attribute for my aar dependency:

compile ('com.somepackage:LIBRARY_NAME:1.0.0@aar'){
    transitive=true
}
