Vaadin 7 - Suddenly stopped working


My team has been using Vaadin 7 since years for a very basic use case. It has been working fine until yesterday when it suddenly stopped working, saying “Error retreiving your subscription key from the server”. We are NOT using a paid subscription.

Has there been a recent change in free support for vaadin 7? Please let us know.

Adding the vaadin dependencies we are using in our Java build.gradle file below :

Thanks for the reply.

I checked the dependencies and found out that it is defaulting to 7.7.23 automatically, even though i am forcing a lower version in build.gradle

vaadin-server - Libraries needed by Vaadin server side applications.
±-- com.vaadin:vaadin-server:7.7.+ → 7.7.23

| -– org.jsoup:jsoup:1.8.3
±-- com.vaadin:vaadin-themes:7.7.+ → 7.7.23
-– javax.servlet:javax.servlet-api:3.1.0


Found the root cause.

Plugin “fi.jasoft.plugin.vaadin” was causing the issue of pulling the newer version.
Downgrading the plugin version fixed the issue.
