I’m using IntelliJ IDEA 8.1.3 and after some difficulties I now have almost everything going just fine.
The only thing I can’t get to work is the external Java Doc, referencing the Vaadin doc only works for classes, documentation for methods just won’t “hook up”.
“Still a bit weird though, that the normal “Attach javadoc” didn’t work. Neighter by URL nor the Vaadin zip-archive.”
It works, but You must specify path to zip archive and_inside zip_.
But as mentioned above vaadin-6.5.x.jar contains sources, so you can attach it as sources and IDEA will generate javadoc “on the fly”.
PS:
But, if you want External javadoc then:
Looks like javadoc inside jar is broken in IDEA 8.1.x
Extract downloaded vaadin.zip in folder and specify it as javadoc e.g. /opt/vaadin-6.5/WebContent/docs/api/
