• Install Maven 3.2.3 or newer.

• Install the Android SDK and set the ANDROID_HOME environment variable to the SDK install directory.

• Clone the Cling source:

git clone https://github.com/4thline/cling.git

• Change into the cling/ directory.

• Install everything into your local ~/.m2 Maven repository (this will take a few minutes if all dependencies have to be downloaded for the first time).

mvn clean install

If your build fails with Android/dex packaging errors, you forgot the clean.

• Use Cling in your pom.xml with:

<dependencies>
  <dependency>
    <groupId>org.fourthline.cling</groupId>
    <artifactId>cling-core</artifactId>
    <version>2.1.2-SNAPSHOT</version>
  </dependency>
</dependencies>
