Transitive dependencies not resolved for aar library using gradle

Question

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.

So:

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' } 

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> 

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' } 

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

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 

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

Answer 1

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

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

Answer 2

you should not use "@aar", if use "@" is become "Artifact only notation", if you want to use "@" and want have dependence transitive, you should add "transitive=true"
