Why is the application not going?

Question

Android

Good afternoon, dear people.
Just started getting acquainted with development for android and Android Studio in particular.
The problem is the following, when building an application (even a "clean", just created Hello World) an error occurs:

Execution failed for task ':app:mergeExtDexDebug'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
   > java.lang.IllegalStateException: Cannot parse result path string:     
   > java.lang.IllegalStateException: Cannot parse result path string:     
   > java.lang.IllegalStateException: Cannot parse result path string:

and so on 20+ lines
Android Studio 3.4, latest version of Java.
Tell me where to dig?
upd: launching the application in the emulator happens without problems

Answer 1

In the compilation settings, set debug and stacktrace, check the cause of the error in the log
