How to exclude jar file from my target Android library assembly

Question

I use Android Studio and have several applications that rely on the same code. I moved the shared code to a separate library to include it in my applications.

The library project ( MyLib ) that I created for this purpose requires compiling a jar file, so I added it to the libs project directory.

My build.gradlemain module MyLib is as follows:

apply plugin: 'com.android.library'

android {
    compileSdkVersion 21
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.android"
        minSdkVersion 9
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }

    buildTypes {
        release {

        }
    }
}

dependencies {
    compile files('./libs/external-java-lib.jar')
}

When I create a project, gradle generates a jar file containing external-java-lib.jar.

I want my Android application projects to provide "external-java-lib.jar", not MyLib. Because in my applications I can use different versions external-java-lib.jar.

gradle external-java-lib.jar ?

library external-java-lib.jar libs.

build.gradle main :

dependencies {
    compile project(':libraries')     
}
