问题
I am running Proguard via the Maven Plugin, you can see my configuration here: https://github.com/sanity/tahrir/blob/proguard-debug/pom.xml#L61
You can see the complete output of "mvn -DskipTests assembly:assembly" here: https://gist.github.com/ee1081179496e11916cb
Despite quite a bit of searching I cannot find any explanation of what causes this error, nor now I can fix it?
回答1:
Your input contains a library class that depends on a program class. ProGuard warns about it and doesn't allow it, unless you specify -dontwarn. You should remove that option and check ProGuard's warnings for details.
See the ProGuard manual > Introduction
See the ProGuard manual > Troubleshooting > Warning: library class ... depends on program class ...

For me, having
proguard.config=proguard-project.txt
caused the same error. Correcting to include both sdk and my config file like below fixed it.
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
