deploy to tomcat subdomain

[MVTec]

I want to deploy x.war in tomcat using cargo plugin "com.bmuschko.cargo-base".
This application runs on subdomain and has a non default appBase.
Moreover behind loadbalancer on two Servers x1.y.de and x2.y.de

tomcat server.xml

<Host
				name="x.y.de"
				debug="0"
				appBase="x_webapps"
				...		
</Host>

defined servers as below in build.gradle

def servers =[
	'x.y.de': [
		'configPath': 'properties/prod/x',
		'remote': [
			[
				'hostname': 'x1.y.de',
				'port': 80,
				'username': 'abc',
				'password': '...'
			],
			[
				'hostname': 'x2.y.de',
				'port': 80,
				'username': 'abc',
				'password': '...'
			]
		]
	]
]

using this for deployment

servers.each { host, server ->
	server.get('remote').each { config ->
		def serverName = config.hostname.replace('.', '').replace('-', '').capitalize()

		task "deployRemote${serverName}"(type: com.bmuschko.gradle.cargo.tasks.remote.CargoRedeployRemote) {
			description = "Deploys WAR to remote Tomcat '${config.name}'."
			containerId = 'tomcat8x'
			hostname = config.hostname
			port = config.port
			username = config.username
			password = config.password
		}
	}
}

This works for application in webapps directory but nor for the ones with subdomain
Any idea, how to get it working?
