eclipse - Your gradle version is too old -

i using gradle within eclipse, installed marketplace (package called buildship). i'm trying load vaadin project.

// tell gradle add vaadin support plugins { id 'fi.jasoft.plugin.vaadin' version '1.0' // tell gradle working in eclipse apply plugin: 'eclipse-wtp' } 

when try refresh gradle project after entering these commands fails. don't think problem commands i've entered final line of error messages says version of grade (2.14.1) old- plugin requires gradle 3.0.0+. can't find instructions of how upgrade version of gradle i'm using?

if use gradle wrapper in project, should have gradle folder in root folder of project. inside gradle\wrapper folder there should 2 files:

• gradle-wrapper.jar
• gradle-wrapper.properties

open gradle-wrapper.properties editor(e.g. notepad). see content below:

#wed jun 29 07:29:15 cest 2016 distributionbase=gradle_user_home distributionpath=wrapper/dists zipstorebase=gradle_user_home zipstorepath=wrapper/dists distributionurl=https\://services.gradle.org/distributions/gradle-2.14.1-bin.zip 

you can change last line , put correct version number follow:

distributionurl=https\://services.gradle.org/distributions/gradle-3.3-bin.zip 

then save file , run gradle.
