I'm trying to pack my project to APK and then obfuscate it with ProGuard.
Here is my pom:

But when I'm trying to run mvn3 clean install -Prelease -X, I've get an error and loooong command. When I'm trying to run that command, I've got:
Warning: com.google.common.collect.AbstractBiMap: can't find referenced class javax.annotation.Nullable
Warning: com.google.common.collect.AbstractBiMap: can't find referenced class javax.annotation.Nullable
Note: the configuration refers to the unknown class 'com.android.vending.licensing.ILicensingService'
Note: there were 1 references to unknown classes.
You should check your configuration for typos.
Warning: there were 1277 unresolved references to classes or interfaces.
You may need to specify additional library jars (using '-libraryjars'),
or perhaps the '-dontskipnonpubliclibraryclasses' option.
Warning: there were 6 unresolved references to program class members.
Your input classes appear to be inconsistent.
You may need to recompile them and try again.
Alternatively, you may have to specify the options
'-dontskipnonpubliclibraryclasses' and/or
'-dontskipnonpubliclibraryclassmembers'.
java.io.IOException: Please correct the above warnings first.
at proguard.Initializer.execute(Initializer.java:308)
at proguard.ProGuard.initialize(ProGuard.java:210)
at proguard.ProGuard.execute(ProGuard.java:85)
at proguard.ProGuard.main(ProGuard.java:499)
And lots of warning about referencing before. What I'm doing wrong?
Eric Lafortune
The warnings say that many classes that you are processing refer to classes that aren't present in the input jars or library jars:
This is a common problem in Android, where you're processing third party libraries that depend on other, missing libraries (but don't really use them in practice). Some Android-specific questions and answers:
- Proguard tells me 'Please correct the above warnings first.'
- proguard hell - can't find referenced class
The (harmless) note says that your proguard.cfg refers to com.android.vending.licensing.ILicensingService, but that class isn't present in your code. You can remove the line from the configuration.
