gradle > 6.5 currently throws a warning and will fail to compile after 7.0 with this plugin:

The BuildListener.buildStarted(Gradle) method has been deprecated. This is scheduled to be removed in Gradle 7.0.

The problem is at line https://github.com/passy/build-time-tracker-plugin/blob/master/src/main/groovy/net/rdrei/android/buildtimetracker/BuildTimeTrackerPlugin.groovy#L29 and the gradle migration guide is not very helpful:

APIs BuildListener.buildStarted and Gradle.buildStarted have been deprecated
These methods currently do not work as expected since the callbacks will never be called after the build has started.
The methods are being deprecated to avoid confusion.
