i was trying to follow this tutorial:
http://www.gdgankara.org/2012/11/01/step-by-step-android-development-with-maven/
but after setting up the environment,
I too had similar problems.
Solved by following steps :
1) Upgrade maven to 3.1.1 2) Use android-maven-plugin 3.6.1 pr greater [I used 3.8.0] 3) Use maven-dependency-plugin 2.8
If you want to build against latest Android SDK [ex : 4.3], follow following additional steps - 4) Install the local copy of android.jar using command mvn install:installFile .. 5) Set 18
Hope this helps.
