Re: excluding GWT-DEV.jar from final build?

Like Vassilis said, therefore best practice is to separate the project into 3:

• Client-side (Web browser), this is where you transpile the Java2JavaScript. The result is always JS / HTML / CSS. You use here gwt-dev.jar, gwt-user.jar but at the end it doesn't play any role since you won't "deploy" them, only pure JS / HTML / CSS. 
• Server-side (Web container / Servlet container), this is your server-side business logic / database. You could have gwt-servlet.jar in this part if you are using GWT server-side functionalities like GWT-RPC, GWT-Logging.
• API / Shared, this is the Java class where you can use from both side like Java Interface, DTO, Validator, etc.

The dependencies should always be like this:

• client-side project depends on API / shared
• server-side project depends on API / shared
• Never let your client-side project depends on the server-side project also another way around
• Only if you want to, you could "copy" the result of JS / HTML / CSS to your server-side project, so your web container could deliver the JS / CSS / HTML to the web browser... But no dependencies.

Hope this helps,

Hi,

I think gwt-dev.jar is where the gwt compiler lives. So you need this jar for compilation.

For deployment:

• You don't need it for client side only projects
• 99% you don't even need it for RPC based servlets

Hope that helps.

hi..

assuming my code will only run in client mode (i.e won't run in any server, or any servlet container) is it save to exclude it from maven dependencies during build? mark it as provided ? 

according to this it seems i can
