adding Vaadin Control Panel to Liferay (liferay-vaadin-plugin-web-1.1.0.0.war does not support this version of Liferay)

Question

I would like to use Vaadin 7 with Liferay 6.2. I downloaded Vaadin Control Panel from marketplace and added .war to deploy folder.

Path to .war of Vaadin Control Panel: /liferay-portal-6.2-ce-ga2/deploy/liferay-vaadin-plugin-web-1.1.0.0.war

Then I opened Liferay Control Panel and tried to activate Vaadin Control Panel in Apps->Utility and got error message: "Portlet is temporarily unavailable." In log message I got error:

com.liferay.portal.kernel.deploy.auto.AutoDeployException: com.liferay.portal.kernel.deploy.auto.AutoDeployException: liferay-vaadin-plugin-web-1.1.0.0.war does not support this version of Liferay

In log I found these error messages:

How do you use latest Vaadin version with latest version Liferay?

As long as the file is still in your deploy folder, it's not deployed. Do you see anything in the log that could help getting to the root cause? — Olaf Kock, Sep 13 '14 at 11:25

The key information is

liferay-vaadin-plugin-web-1.1.0.0.war does not support this version of Liferay

e.g. the authors probably have created/tested this plugin on 6.1 (likely), or got the declaration of compatible versions wrong (unlikely). In fact, if I look at marketplace, the plugin indeed declares compatibility with 6.1, not 6.2. However, the marketplace app links to the sourcecode and the README file indicates that it might have already been ported to 6.2 - just not released on marketplace. You might want to check compiling it yourself.

As to your closing question of how to use the latest Vaadin version with Liferay, you might want to check this article

Thanks for your reply. I have no experience with vaadin neither liferay. At first, I read Book of Vaadin and noticed a section about integration vaadin 7 into liferay and tried to deploy my first portlet in liferay. — Matt, Sep 13 '14 at 13:05
