Error using Gradle Vaadin Plugin - gradle

Question

I am trying to add Gradle Vaadin Plugin to my project, but I get the below error.

Here is the page for the plugin: https://github.com/johndevs/gradle-vaadin-plugin/wiki

springBoot {

}
When I check the gradle dependencies, I see 2 version of the "javax.validation:validation-api".
I believe that is causing the problem, but I could not find a way to force vaadin-client to use "javax.validation:validation-api:1.0.0.GA".
I appreciate if you can help me to correct the build.gradle.

Answer 1

The Gradle Vaadin plugin must see the Springboot plugin to do a proper setup. So you have to first use the Springboot plugin, then afterwards the Vaadin plugin.
The reason for the error you see there is, that the dep for javax.validation 1.1 from Springboot overrides all configurations (also the one used to build the client for Vaadin)
On a side note: you apply the Springboot plugin twice -- once in plugins, once with apply. I'd get rid of the buildscript-block and the apply. Then swap the items in plugins.
