Vaadin plugin doesn't work with vaadin 6 and liferay 6.2?

Vaadin 6 / 7 / 8
1

Using eclipse 4.4 with liferay and vaadin plugins:

  2. New → Project → Vaadin 6 Project
  3. enter name (I used “v6”), choose deployment “Generic portlet (Portlet 2.0)” and vaadin version 6.8.12
  4. check “Generate web.xml deployment descriptor”
  5. click “Finish”
  6. in “Servers” tab right-click “Liferay v6.2 ga5 (Tomcat 7) at localhost”
  7. Add and Remove → v6 → Add > → Finish
  8. Start the Server

“v6” doesn’t appear in list of portlets available to add to pages, in fact the portlet’s category “Vaadin” (from liferay-display.xml: ) doesn’t appear at all.

The only mention of “v6” in the log is:

INFO: Deploying web application directory /home/kf/liferay/liferay-portal-6.2-ce-ga5/tomcat-7.0.62/webapps/v6 Apr 18, 2016 4:43:54 PM org.apache.catalina.startup.TldConfig execute INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

What am I doing wrong?
