gradle - Method must be overridden in [proguard.optimize.peephole.ClassMerger] if ever called” in Android Studio -
seen @ least 2 similar questions, both considering eclipse non gradle builds.
i'm trying assemble release gradle using:
./gradlew myapp:assemblerelease --stacktrace
besides newest google proguard example proguard.txt contains:
# butterknife -keep class *$$viewinjector{} -dontwarn butterknife.views$injectviewprocessor -dontwarn butterknife.internal.** #jodatime -dontwarn org.joda.time.** #apache -dontnote org.apache.** -dontwarn org.apache.**
this seemed remove warnings struggling mysterious
caused by: java.lang.unsupportedoperationexception: method must overridden in [proguard.optimize.peephole.classmerger] if ever called
...and have no clue means.
i had same issue , never discovered root of issue. did find if add rule skip optimization in proguard file stops build error happening.
