Clear The Screen in Continuous Runs

[gregorriegler]

When you run your tests in continuous mode,
./gradlew test -t
the plugin should clear the commandline screen before printing the next test report, just like mocha does.
so your result always starts nicely at the top.
would like to use this when doing tdd.

Here is a similar issue:

This is how they did it in the tdd-gradle-plugin

class ContinuousClearPlugin implements Plugin<Project> {

	@Override
	public void apply(Project project) {
		if (project.gradle.startParameter.continuous) {
			project.gradle.addListener( new BuildAdapter() {
				void projectsEvaluated(Gradle gradle) {
					if (System.getProperty("os.name").startsWith("Windows")) {
						project.exec { commandLine 'cls' }
					}
					else {
						project.exec { commandLine 'clear' }
					}
				}
			});
		}
	}
}
