Gradle: How to publish a Android library to local repository

Question

I have a library and a Android app using Gradle and Android Studio. I can include the library directly in the project as following

compile project(':library')

Because I don't want to mesh up with library source code, I want to publish the library into local repository so that I can use as

compile 'com.mygroup:library:1.0'

Any advise?

Answer 1

I just found a solution. In the build.gradle of the library project, add this

apply plugin: 'maven'

group = 'com.mygroup'
version = '1.0'

uploadArchives {
    repositories {
        mavenDeployer {
            repository(url: "file://[your local maven path here]")
            // or repository(url: mavenLocal().getUrl()) 
        }
    }
}

In the project folder, type following command

gradle uploadArchives

For an Android Library you should use the Android Gradle-Maven plugin https://github.com/dcendents/android-maven-gradle-plugin:

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.3'
    }
}

apply plugin: 'com.android.library'
apply plugin: 'com.github.dcendents.android-maven'

Then to publish to your local repository run:

./gradlew install

which will install it in $HOME/.m2/repository. In your app or other project you can then include it by adding mavenLocal() to your repositories.

Alternatively, if your library is on GitHub then you can simply include it in other projects using JitPack. Then you don't have to run the above command and can just use what's been pushed.

Publish de library on your local maven repository and then on your gradle use

repositories {
  mavenLocal()
}

If you have other repositories listed, make sure your mavenLocal appears first.
