A plugin to merge dependencies(aar/jar) into aar file.

This plugin can embed dependency(local or remote) to aar file, when an app module includes the aar file, the aar's dependencies code and resource can be referenced directly, no need to import once again.

This plugin support android gradle plugin 3.0.0-3.4.2 and gradle 4.6-5.1.1.

Add snippet below to your root project's build.gradle file:

buildscript {
  repositories {
    jcenter()
  }
  dependencies {
    classpath 'com.cpdroid:fat-aar:1.1.0'
  }
}

Add snippet below to you library module's build.gradle file:

apply plugin: 'com.android.library'
apply plugin: "com.cpdroid.fat-aar"

make sure 'com.cpdroid.fat-aar' is appied after 'com.android.library'

Then you can use keyword "embedded" instead of "implementation" or "compile" to package target dependency to your generated aar file:

embedded fileTree(dir: 'libs', include: ['*.aar'])
embedded project(':moduleA')
embedded 'com.gongwen:marqueelibrary:1.1.3'

Run gradle assemble task, normally "assembleRelease", copy the generated aar file to your app module's libs directory and include the generated aar file in app module's build.gradle file:

implementation fileTree(dir: 'libs', include: ['*.aar'])

Then you can reference the aar and it's dependencies code and resources.

An example can be found here

Add fataar closure in library module's build.gradle file:

apply plugin: 'com.android.library'
apply plugin: 'com.cpdroid.fat-aar'

android {
    compileSdkVersion 28
    ...
}

fataar {
    verboseLog true
    ignoreAndroidSupport true
    ignoreDependencies 'com.google.code.gson:gson:2.8.2'
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    ...
}

fataar closure is optional, and is in the same level with android and dependencies. Below is the detailed configuration:

• verboseLog: Default vaule is false, set to true to show more log
• ignoreAndroidSupport: Whether ignore android support package automatically, default is true, false means won't ignore android support package
• ignoreDependencies: Determine which dependency won't be embedded into aar, we can use it as follows:
  • match the 'group:name:version' pattern

    ignoreDependencies 'com.google.code.gson:gson:2.8.2'

  • only match the 'name' pattern(part between two colon):

    ignoreDependencies 'gson'

  • regex match:

    ignoreDependencies '^com.android.*'

  • you can add more than one ignoreDependencies, and it accept more than one patten:

    fataar {
        ignoreDependencies 'com.blankj:utilcode:1.23.7', 'gson'    //accept more than one pattern,split by ','
        ignoreDependencies '^com.android.*'                        //add the second ignoreDependencies
    }

Any dependency matched the three pattern above will be ignored, and won't be packaged into aar file.

Set verboseLog to true to see more log like this:

> Task :mylibrary:decompressFreeReleaseDependencies
   pattern:[com.google.code.gson:gson:2.8.2], artifact:[com.google.code.gson:gson:2.8.2]
   Ignore matched dependency: [com.google.code.gson:gson:2.8.2]

pattern is your configuration, artifact is the dependency, if it matched the log will show
'Ignore matched dependency: [com.google.code.gson:gson:2.8.2]'

• All android support packages and android jars will be ignored automatically, you must import them in your app module. The detailed ignored package can be found in the log:

> Task :moduleA:decompressReleaseDependencies
   Ignore android package: [android.support.v7.appcompat]
   Ignore android package: [android.support.fragment]
   Ignore android jar: [com.android.support:support-annotations]
   Ignore android package: [android.arch.lifecycle]
   Ignore android jar: [android.arch.lifecycle:common]
   Ignore android jar: [android.arch.core:common]

• All "app_name" attributes in embedded modules will be deleted automatically as a few modules has the attributes, and it will conflict while compiling. If you have referenced a module's app_name, define an app_name in your library's values.xml file. The detail will be showed as follows:

> Task :moduleA:addReleaseSourceSets
   Found value [app_name] in [D:\workspace\fat-aar-sample\moduleA\build\fat-aar\exploded_aar\com.gongwen\marqueelibrary\1.1.3\res\values\values.xml]
   Delete 1 values...
