I am trying to build the Zxing android app (not the libraries) using the instructions here. I was able to build the jars but cannot build the app itself. When I run mvn package android:apk I get the following error:
[INFO] Scanning for projects...
[ERROR] [ERROR] Some problems were encountered while processing the POMs:

Any help would be greatly appreciated. Even better would be some instructions on building the app with Android Studio.
You can see where the error is from the following line
[ERROR] 'dependencies.dependency.version' for com.google.android:android:jar is missing. @ line 34, column 17
You will need to add a valid <version> tag to the dependency. Checking the Maven repository for the artifact, we can see the latest version is 4.1.14.
Ensure your POM containing the dependency looks like
<platform.version>4.1.1.4</platform.version>
This was also mentioned as an answer here so I imagine you're having the same problem.
