Error Android version missing

[Askia]

Hello all,
Following the getting started instructions I downloaded the android
sdk and the masa plugins.
I get stuck at step 7 after creating pom xml. The pom xml in question
is just a modification of the sample pom included in the readme file.
I had initially downloaded the 1.0_r2 sdk then noticed that the code
was referencing 1.1_r1. So i also downloaded the 1.1_r1 dev version
and changed my android variable to point to the new path. I am still
getting the same error.
Can you please help?

mvn -X install:install-file -Dfile=$ANDROID_SDK/android.jar -
DgeneratePom=true -DgroupId=android -DartifactId=android -
Dversion=1.1_r1 -Dpackaging=jar
