Hot deploying changes with Netbeans, Maven, and Glassfish

netbeans glassfish maven war hotdeploy

Recently we migrated from using ant to maven. Within Netbeans, I used to edit and save html, xhtml, javascript, css files in the WAR and almost immediately the changes were available on the server.

Now, when I edit and save those types of files in the WAR, nothing happens. I have to right click my EAR -> Build with dependencies -> Run to make the changes available. This process takes ages.

I've found a few similar questions, but am still confused.

EDIT: I just wiped my development environment and setup from scratch again. Then I duplicated the setup on a co-worker's machine (him on Windows, me on Ubuntu). With the same setup process, less different OSs, he can edit/save xhtml files and see the changes without additional steps!

To enable hot-deploy, enable the "Compile on Save" feature in Netbeans. In your POM, add this property:

<netbeans.compile.on.save>all</netbeans.compile.on.save>

This property will be inherited, so if you have a parent project, you may consider putting it there.

Note that there is a bug in which the change is not reflected in the UI, so it will look like the property has no effect, but you'll notice that hot-deploy works.
