Naive way to deploy application to remote server using gradle task named : deploy_dev

build.gradle

remotes {
  web01 {
    role 'webServers'
    host = 'host.example.com'
    user = 'userA'
    knownHosts = allowAnyHosts
 	identity = file('id_rsa')          //id_rsa generated file for authentication 
  }
}

task deploy_dev << {
  ssh.run {
    session(remotes.role('webServers')) {
      
        def appServerPath = project.property('dev.appserver.location') + '/bin/'
    	def cd_appServerPath = 'cd ' + appServerPath
      	
      	def webappsPath = project.property('dev.appserver.location') + '/webapps/'
      	def cd_webApps = 'cd ' + webappsPath
      	 
      	def shutdownTomcat = cd_appServerPath + ' && ./shutdown.sh' 
        def startTomcat = cd_appServerPath + ' && ./startup.sh'
        def delete_war_file = cd_webApps + ' && rm -rf app*'  
        
		execute shutdownTomcat
        execute delete_war_file
        put from : project.property('war.location'), into : webappsPath 
    	execute startTomcat
     }
  }
}
