Have you tried using a newer version of the Spring Boot Gradle plugin, perhaps 2.0.0.RELEASE or newer?

The problem that you met is due to a missmatch in spring versions. To get the project up and running just update the build.gradle dependencies I had the project running fine with the following configuration:

buildscript {
    repositories {
    dependencies {

plugins {
    id 'java-library'

apply plugin: 'org.springframework.boot'

repositories {

dependencies {


sourceCompatibility = 1.8
targetCompatibility = 1.8
String buildName = 'vaadin-spring-example'

jar {
    baseName = buildName
