Gradle HttpFileServer, keep running, but kill on ctrl+c - gradle

Question

During my Gradle build I need to run a simple web server to serve some static content. I’m using Gradle’s integrated classes for that.
Here's a very simple version of my build.gradle:
apply plugin: 'groovy'
task server() {
doLast {
def root = new File(project.buildDir, '/site')
def port = 8765
def factory = new SimpleHttpFileServerFactory();
def server = factory.start(root, port)
println "HTTP server started on $port"
}
}
I'm facing the following two issues:
When running gradle server, gradle executes, starts the server, and then quits (with the daemon obviously staying in the background and the server running, which leads to the second problem)
I’ve no possibility to stop the server through gradle. When running gradle server again, I get an exception because the port is in use.
I’d fancy either of the following solutions:
When running gradle server, gradle keeps running until I hit ctrl+c, then the server is killed as well
There are two tasks, gradle startServer and gradle stopServer which are used to start and stop
How can I achieve this or is there a different, better solution?

A little hack-ish but it works, the server task will hang and the SIGKILL will kill the server too
apply plugin: 'groovy'
task server() {
doLast {
def root = new File(project.buildDir, '/site')
def port = 8765
def factory = new SimpleHttpFileServerFactory();
def server = factory.start(root, port)
println "HTTP server started on $port"
while(true) Thread.sleep(1000)
}
}
