sdk setup, LR6.2, vaadin7, java8?

[Jan Agermose, geändert vor 9 Jahren.]

hi

im trying to get going with this combination - Im using java 8 (on windows), intellij, vaadin 7 when time comes - and so commandline for compiling and deploying. Liferay is up and running with vaadin7. After fixing some references "create.bat" is working and intelliJ is setup. When I compile/deploy I call "ant deply" on the commandline.

two things 1) I would like to not have vaadin.jar in every portlet I create and deply and the files are already in webapp/ROOT/.../lib so that should be possible - just the ant compile part needs to know of the jars. Why are they not included standard?

2) in any case I get problems that seams to relate to me running java 8 - is this not possible? See below

I don't see Java 8 as officially supported by Liferay 6.2, so use Java 7.

Also, if you are using Vaadin 7, you will need to upgrade the Vaadin from the v6.* that which comes with Liferay v6.2. To upgrade Vaadin in Liferay, just use one of the two very good Vaadin Control Panels that are available in the marketplace.

And if you are setting up a new environment, why not use Maven instead of the SDK with Ant ? Maven use in IntelliJ is very straight forward tho command line works well too. There are even some intro Vaadin 7 portlet maven archetypes available that you might start with and/or be interested in looking at.
