It seems that there is a compatibility issues between android-maven-plugin and the maven release 3.2.5 and later.

For me it works on a 3.2.3 and fails with NoClassDefFoundError exception when I use 3.2.5 and 3.3.1

Try to download an older maven version from the archives at http://archive.apache.org/dist/maven/maven-3/3.2.3/

Edit

This issue is fixed in later versions(testet with 4.1.1) of the android-maven-plugin. The plugin has moved to github, and is relocated to a new groupId.

  <plugin>
    <groupId>com.simpligility.maven.plugins</groupId>
    <artifactId>android-maven-plugin</artifactId>
    <version>4.1.1</version>
  </plugin>

New project location: https://github.com/simpligility/android-maven-plugin/

There is some compatibility problem for maven 3.2 & 3.3. Try this:

brew install homebrew/versions/maven31
sudo ln -s /usr/local/Cellar/maven31/3.1.1 /usr/local/Cellar/maven/
brew switch maven 3.1.1
