Not Found - org.springframework.boot:spring-boot-starter-tomcat:2.0.0.M2 about spring-websocket-chat HOT 4 CLOSED

I had the same problem i changed the SpringBootVersion in build.gradle as follows:
springBootVersion = '1.5.8.RELEASE'
then
gradle clean
gradle bootRun

from spring-websocket-chat.

I had same issue, but fixed in build.gradle:

//maven { url "http://repo.spring.io/libs-release" }
maven { url "http://repo.spring.io/plugins-release" }

This allows to preserve

springBootVersion = '2.0.0.M2'

from spring-websocket-chat.

Found same problem with 2.0.0.RELEASE
Fixed in build.gradle:

dependencies {
// ... //
compile group: 'org.springframework.boot', name: 'spring-boot-starter-tomcat', version: '2.0.0.RELEASE'
// ... //
}

P.S.: Great thanks to @salmar for this repository.

Upgraded the sample to Spring Boot 2.0.0.RELEASE, spring-boot-starter-tomcat is a transient dependency of spring-boot-starter-web
