Error: Execution completed for task ": app: proguardRelease". java.io.IOException: Execute the above warnings first.

I am new to Android Studio. I am trying to generate a signed apk file using android-studio.

When building a signed release APK, it gives me an error like below.
In this module I only have four library files, they are
checked in the list of dependencies in the build.gradle file.

Please clarify what dependencies or build types I missed in this process.

I found some solutions from other users, they said delete all library files and add this again, then it solves the problem. I tried so hard too, but it doesn't work for me.

But when I tried to build release apk file with release it gives me below error warning.

I have a problem with proguard. I get this on the console page. I added the line -dontworn to proguard-project.txt

Please clarify my doubts.
