run multiple jetty in gradle

Background:
I have a selenium test suite for end-to-end web testing.
Currently, it is running on jenkins box but it is taking so long to finish all the tests.
So, next step is to parallelize the selenium tests.
As a first step, I need to start multiple jetty servers using different port.

With Gradle jetty plugin, I camp up how to run the multiple jetty servers before tests.

	// start multiple jetties before test
	//
	// useful for parallel web end-to-end testing
	//
	import org.gradle.api.plugins.jetty.JettyRun
	apply plugin: 'java'
	apply plugin: 'jetty'
	repositories {
	mavenCentral()
	}
	// configuration for each jetty server
	def jettyConfigs = [
	[port:8001],
	[port:8002]
	]
	def jettyMultiRunTasks = []
	// create jetty tasks and assign them
	jettyConfigs.eachWithIndex {jettyConfig, index ->
	jettyMultiRunTasks << task("jettyMultiRun-${index}", type: JettyRun) {
	httpPort = jettyConfig.port
	daemon = true
	// more configuration to specify each jetty to use different env...
	}
	}
	test {
	// start jetties before running tests
	dependsOn(jettyMultiRunTasks)
	// more test options such as maxParallelForks, etc.
	}
