Hello, I created a Hello World GWT application with Eclipse;

With everything default, when i run project then hit refresh here is the compilation durations;

Compilation succeeded -- 0.816s Linking succeeded -- 0.413s 1.340s total -- Compile completed

When i include vaadin dependency in .gwt.xml file <inherits name="com.vaadin.polymer.Elements"/>compliation takes painly long.

Compilation succeeded -- 1.080s Linking succeeded -- 12.925s 26.170s total -- Compile completed

I dont even use any widget yet. This happens everytime. I mean, when i change single line of code, it tooks 30 sec or even longer sometimes, for page to show up.

The library includes more than 600 classes, that makes that gwt compiler takes a while until reads everything. There is no solution but removing stuff. I would recommend you to create your own library and import it, or just use the gwt-api-generator in your demo via the front-end-maven plugin. In the demo we show how to do that: https://github.com/vaadin/gwt-polymer-elements/blob/master/demo/pom.xml#L151
