Why Vaadin 7 is much slower to compile than Vaadin 6?

Vaadin 6 / 7 / 8
1

Hi,
We’ve been using Vaadin 6 for 3 years now and we loved it!
Vaadin 7 went out and we thought: “let’s give it a shot!”
Unfortunately, it seems you guys included GWT inside the vaadin now (as CORE COMPONENT) and it seems we’re working with GWT from now on.

I don’t know what it’s the different but in Vaadin 6 I don’t have the follow output (project was created through the command: mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-application -DarchetypeVersion=7.0.3 -Dpackaging=war)

This kind of output is very familiar to me, when you use GWT it happens all the time.

Question: Why it has to happen? I don’t have anything created for GWT. As you can see, it took 2:02.758s to build a dumb project (just created from archetype, didn’t add anything).
Btw, Im running this with my MacbookPro 8GB RAM i7 quad core.

So I want to know how to skip this entire GWT compile thing.

Thanks in advance.

This is the output from building the widgetset (something I do in Liferay all the time).

If you don’t need to compile your own widgetset, I think you can get away with using the client-compiled jar, although I’m not sure how you’d affect the change to prevent maven from compiling it for you.

BTW, GWT is there with Vaadin 6 also (it also had an opportunity to compile your own widget set). I think the difference is the use of Maven and getting the POM set up correctly.

Thanks very much.
I’ve removed all dependencies that are not using the compiled version of the jar (like themes and client) and also I’ve removed the vaadin plugin (the one responsible for compiling the widgetset) now everything is like vaadin 6.
I will run the project into my glassfish to check whether everything is working.
Thanks in advance.

Dave’s correct. In this regard, Vaadin 7 is just like Vaadin 6, you don’t need to compile the widget set if you just use the precompiled version (i.e. core widgets). I think the Maven plugin is just being ignorant here and compiles it just in case.

5

I’d like to add that the Maven plugin is working exactly the same way as it (and the GWT plugin before it) always have. It has a hard time determining which changes might affect the client side, so it almost always recompiles it when there are changes in the project.

The difference you see is in the archetype, which now compiles the widgetset by default. You can move widgetset compilation under and then run the goals vaadin:update-widgetset and vaadin:compile manually when necessary to get control over it.

In the longer term, restructuring the archetype so that there is a separate module for the widgetset is the way to go when we have time to do that, but that will require a major rework of the archetype. The upcoming widget archetype already has a structure that is somewhat similar (though not the same) as the application archetype should have.
