I am trying to get setup to use Maven and pom.xml files in Eclipse for my Android projects. I have Eclipse Indigo setup (m2e included), Android SDK installed, ADT installed. I am struggling to understand what it means to "Install the m2e-android-plugin" (I am always taken to this page which provides instructions on installing it, but which I cannot follow) Specifically, when I go through the instruction on that page, after I complete all the steps in part 2, my structure does not have "Maven Dependencies" and my pom.xml file shows the following error:
Project build error: Unresolveable build extension: Plugin
com.jayway.maven.plugins.android.generation2:android-maven-plugin:3.1.1 or one of its dependencies could
not be resolved: The following artifacts could not be resolved:

I have tried set up a fresh second IDE myself and everything works as expected, suppose you have installed both Android SDK and Maven properly (better to use latest version), these are the only Eclipse plugins required to work with Mavenized Android Project:
- adt
- m2e
- m2e-android
Check out my screenshot Help -> Install New Software... -> what is already installed:
If you follow instructions from this page starting with a new project, the <packaging> error is most likely due to earlie version of maven-release-plugin (if you do not explicitly specify one). By hovering mouse on <packaging> element in pom.xml, you should get some hint like:
maven-resources-plugin prior to 2.4 is not supported by m2e. Use maven-resources-plugin version 2.4 or later.
Adding the following plugin under <plugins>:
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>2.5</version>
</plugin>
Then Right-click on new project and select Maven -> Update Project Configuration, this should fix all error and give you a working example.
I had the same problem trying to install the android m2e in eclipse JUNO. Then tried to install through "Install new software" wizard, instead of market place.
Add the following as an update site and select "Android For Maven eclipse" from the listed softwares and install.
