Gradle Maven plugin "install" task does not work with Android library project

I want to install android library project to local maven repository. Here is build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android-library'
apply plugin: 'maven'

version = "1.0.0-SNAPSHOT"
group = "com.example"

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 18
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 18
    }
}

When I run:

gradle install -i

it gets stuck here:

Executing task ':project:installTest' due to:
  Task has not declared any outputs.
Starting process 'command 'd:\android-sdk-windows\platform-tools\adb.exe''. Working directory: D:\Projects\java\....... Command: d:\android-sdk-windows\platform-tools\adb.exe install -r D:\Projects\java\.......\build\apk\project.apk
An attempt to initialize for well behaving parent process finished.
Successfully started process 'command 'd:\android-sdk-windows\platform-tools\adb.exe''
> Building > :project:installTest

So first thing I noticed is that it's trying for some odd reason to deploy it on a device as APK.

Am I doing something wrong or is it just android-library plugin not compatible with maven plugin?

Edit: Please refer to the github page (https://github.com/dcendents/android-maven-gradle-plugin) for the latest instructions and find the correct version to use. The original instructions are not suitable anymore with the latest gradle release.

Original Post:

I've modified the maven plugin to be compatible with android library projects. See the project on github: https://github.com/dcendents/android-maven-gradle-plugin

Configure your android library projects to use it:

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.github.dcendents:android-maven-plugin:1.0'
    }
}

apply plugin: 'android-library'
apply plugin: 'android-maven'

Then you should be able to install aar into your local maven repository using the install task.

Hope this helps, if you find issues with the plugin please let me know on github and I'll fix it.

Elaborating on CyclingSir's answer, I propose to add a separate "installArchives" task. This should also take care of picking up your custom artifacts (e.g. sources).

apply plugin: 'maven'

task installArchives(type: Upload) {
  description "Installs the artifacts to the local Maven repository."
  configuration = configurations['archives']
  repositories {
    mavenDeployer {
      repository url: repositories.mavenLocal().url
    }
  }
}

Note that with Gradle Android plugin v0.5.5, gradle install still tries to install something on a device.

There's an easier solution if you don't want to use a custom plugin. Instead, just recreate the install task with a different name. I called it installArchives. Add the following code to your build.gradle:

task installArchives(type: Upload) {
    description "Installs the artifacts to the local Maven repository."
    repositories.mavenInstaller {
        configuration = configurations.default
        pom.groupId = 'my.group'
        pom.artifactId = 'my-artifact'
        pom.version = '1.0.0'
    }
}

You can now run gradle installArchives to install your aar locally.
