Content is not allowed in prolog. in android studio

In android studio, the project sync is successful. But when I try to build or run the project it shows the error 'Content is not allowed in prolog'. I tried invalidate caches but in vain. I also tried to clean and rebuild project but it didn't work.

Here is my gradle build log

Task :app:processDebugResources [Fatal Error] aapt2-4.2.1-7147631.pom:2:1: Content is not allowed in prolog.

Task :app:processDebugResources FAILED

  • Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
Solution

  • I was using the latest version of gradle classpath dependency

    classpath "com.android.tools.build:gradle:4.2.1"

    I changed it to

    classpath "com.android.tools.build:gradle:4.2.0"

    Magically, all errors are gone.
