<No stacktrace options>::
No stacktraces are printed to the console in case of a build error (e.g., a compile error). Only in case of internal exceptions will stacktraces be printed. If the `DEBUG` log level is chosen, truncated stacktraces are always printed.

== Logging Sensitive Information

Running Gradle with the `DEBUG` log level can potentially expose sensitive information to the console and build log.

This task does one simple thing: it prints out the version of the project to the command line.

The class extends `DefaultTask` and it has one `@Input`, which is of type `Property<String>`.
It has one method that is annotated with `@TaskAction`, which prints out the version.

            is KaAnnotationList -> renderAnnotationsList(value, printer)

            is FqName -> printer.append(value.asString())
