Download checker-qual-android JAR file with all dependencies

Checker Qual Android is the set of annotations (qualifiers) and supporting classes used by the Checker Framework to type check Java source code. The checker-qual-android artifact is identical to the checker-qual artifact, except that in checker-qual-android annotations have classfile retention. The default Android Gradle plugin retains types annotated with runtime annotations in the main dex, but strips out class-retention annotations. Please see artifact: org.checkerframework:checker
