java.lang.NullPointerException on soot.dexpler.DexAnnotation.handleClassAnnotation(DexAnnotation.java:157)

I cloned the project and built (with mvn install). The variable ANDROVOV points to the "target/androcov-1.0.jar" file. Here is what I get when trying to instrument the apk of the 2048 game. I tried this on the android.jar for APIs 23 and 28.

wahoo:~/Android/Sdk/platforms/android-23> java -jar ${ANDROCOV} -o com.uberspot.a2048_25.mod.apk -i com.uberspot.a2048_25.apk -sdk android.jar
