I have successful deploy and Add this portlet on Liferay Server but there is a red message in web browser "Liferay 7 Vaadin portlet is temporarily unavailable." This is the error in Tomcat error log:

Unfortunately, the issue is not going to be fixed in any visible future. I'm going to archive the repository.
