When we try to deploy an Android to Sonatype Nexus using Gradle Sonatype Nexus plugin, we will encounter (at least in my case) two errors.

The first one is because nexus plugin can’t find install task on the project.

A problem occurred configuring project ':app'.
> Failed to notify project evaluation listener.
   > Task with name 'install' not found in project ':app'.
   > Could not find property 'poms' on project ':app'.

And the second one seems to be that plugin can’t find where source are located.

A problem occurred configuring project ':library'.
> Failed to notify project evaluation listener.
    > Could not find property 'main' on SourceSet container.
    > Task with name 'install' not found in project ':library'.
    > Could not find property 'poms' on project ':library'.

The easiest solution I have found by now, is using Sonatype Nexus plugin in combination with Gradle Android Maven plugin.

First we need to add both plugins to the buildscript closure

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.13.2'
        classpath 'org.gradle.api.plugins:gradle-nexus-plugin:0.7.1'
        classpath 'com.github.dcendents:android-maven-plugin:1.1'
    }
}

Now we’re ready to go, just apply both plugins and define sources location.

    apply plugin: 'android-maven'
    apply plugin: 'nexus'

    sourceSets {
        main {
            java.srcDirs = ['src/main/java']
        }
    }

Finally pom’s data needs to be defined, you can find a sample on Gradle Sonatype Nexus page. For more details on how to configure each plugin, please go the their respective pages.
