Android app is not building in Unity, Error “Gradle initialization failed.”

I am getting an error while building the Android app in Unity. "Gradle build failed. See the console for details."

I am getting this error:

 CommandWithNoStdoutInvokationFailure: Gradle initialization failed
 UnityEditor.Android.Command.RunWithShellExecute.....(very long error message)....
 FAILURE: Build failed with an exception.
 * What went wrong:
 Java heap space
 * 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.

I am using latest Version of Unity 2019.1.4f1. I tried building a blank app. But it is not able to build.
