Creating an Android LIbrary Jar Using gradle with Dependencies

Question

I am trying to create a .Jar file from an Android library project (non-executable) using gradle with dependencies, but I get a NoClassDefFoundError because it accesses one of the files from the dependency modules.

So far I have tried the FatJar method, but it includes everything in the Jar file, except for the Dependent libraries.

What should I do?

UPDATE

My Gradle.build file

apply plugin: 'android'

    android {
        compileSdkVersion 22
        buildToolsVersion "21.1.2"

        defaultConfig {
            applicationId "com.myapplication"
            minSdkVersion 9
            targetSdkVersion 22
            versionCode 1
            versionName "1.0"
        }
        buildTypes {
            release {
                runProguard false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
        sourceSets {
            main {
                java {
                    srcDir 'src/main/java'
                }
                resources {
                    srcDir 'src/../lib'
                }

            }
        }
    }

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile 'com.android.support:appcompat-v7:22.0.0'
        compile 'com.google.code.gson:gson:2.2.4'
    }

    task deleteOldJar(type: Delete) {
        delete 'build/libs/AndroidPlugin.jar'
    }
    task exportJar(type: org.gradle.api.tasks.bundling.Jar) {
        //from('build/intermediates/bundles/release/')
        //from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
       // archiveName = "yourjar.jar"

        from {

            configurations.runtime.collect {
                it.isDirectory() ? it : zipTree(it)
            }

            configurations.compile.collect {
                it.isDirectory() ? it : zipTree(it)
            }
        }
        into('release/')
        include('classes.jar')
        ///Give whatever name you want to give
        rename('classes.jar', 'AndroidPlugin.jar')
    }

    exportJar.dependsOn(deleteOldJar, build)

, Fat Jars: https://github.com/musketyr/gradle-fatjar-plugin. java, com.android.library btw.

, . Jar Zip. , .

, Fat Jar / Maven:

...

apply plugin: 'maven-publisher'

publishing {
    publications {
        maven(MavenPublication) {
            artifact bundleRelease
        }

        mavenJava(MavenPublication) {
            artifact fatJar
        }
    }
}

task fatJar(type: Jar) {
    from (zipTree('libs/library-one.jar'))
    from (zipTree('libs/library-two.jar'))
    from (zipTree('libs/library-three.jar'))
    from ('build/intermediates/classes/release/') {
        exclude '**/BuildConfig.class'
        exclude '**/R$*.class'
        exclude '**/R.class'
    }
}

...

:

$ ./gradlew clean build publishToMavenLocal

P.S. , libs ( *.jar), lib .

Answer 2

APP "libs" . Android Studio.

APP
 -libs
 -src
 -build

gradle:

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


    compile files('libs/NameOfJar.jar')



}
