Hot Reloading

Some tips and tricks to speed your development.

DCEVM and HotSwapAgent

DCEVM together with HotSwapAgent can speedup your development. It enhance the ability of reloading of changed classes especially with scala.

Hot Scene Reloading

Reloading can be used for:

• CSS
• FXML
• Bundle Content

Setup

Create a new method in your ApplicationController:

 def reload(): Unit = {
    // Styling
    reloadStyles()
    // Resources
    applicationEnvironment.clearResourceBundleCache()
    applicationEnvironment.loadResourceBundle("bundles/application")
    // FXML
    val newMainViewController = getController[MainViewController]()
    replaceSceneContent(newMainViewController)
  }

Create a Button anywhere in your application and an corresponding action:

  def actionReload(event: ActionEvent) {
    getBean[ApplicationController]().reload()
  }

IntelliJ

Very useful for compile on save is the Save Actions Plugin
