Com.android.tools.r8.utils.abortexception: Error: Program Input - Unsupported Source File Type

After I upgraded my android project to androidX I get the following build error: org.gradle.execution.MultipleBuildFailures: Build completed with 1 failures. at org.gradle.init

Solution 1:

This has been fixed in Android Gradle Plugin 3.5.0-beta05, see http://issuetracker.google.com/136195384.

To use it either download Android Studio 3.5.0-beta05, or use the following in the top level build.gradle file.

classpath 'com.android.tools.build:gradle:3.5.0-beta05'
