Spring Boot Gradle Tomcat 8

The Spring Boot reference guide provides instructions for upgrading to Tomcat 8 by setting a custom property in Maven: 

<properties>
  <tomcat.version>8.0.3</tomcat.version>
</properties>

What is the equivalent way to do the same in a Gradle build?

I have tried the following to no avail. It stays on version 7.0.52 at app startup.

buildscript {
  ...    
  ext['tomcat.version'] = '8.0.3'
  ...
}

This is how I could configure Spring Boot1.3.3 to work with Tomcat v8.0.33. By default it works with version 8.0.32 and that version has the Websocket problem. 

  compile("org.springframework.boot:spring-boot-starter-web") {
    exclude module: "spring-boot-starter-tomcat"
  }
  //providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
  compile 'org.apache.tomcat.embed:tomcat-embed-core:8.0.33'
  compile 'org.apache.tomcat.embed:tomcat-embed-el:8.0.33'
  compile 'org.apache.tomcat.embed:tomcat-embed-logging-juli:8.0.33'
  compile 'org.apache.tomcat.embed:tomcat-embed-websocket:8.0.33'

For setting up version of tomcat I used:

    dependencies {
    compile("org.springframework.boot:spring-boot-starter-web:${springBootVersion}") {
        exclude module: "spring-boot-starter-tomcat"
    }
    compile 'org.springframework.boot:spring-boot-starter-tomcat:1.1.8.RELEASE'
}

where you just need to find which spring-boot-starter-tomcat suits your needs

Please, have a look at Gretty plugin: it supports Tomcat 8 (as well as Tomcat 7, Jetty 7/8/9) and SpringBoot out of the box. No dependency tweaking is needed.

Gradle has no equivalent of a "parent pom", so you have to call out the dependency explicitly. Because it's groovy you can probably do it programmatically, something like:

configurations.all {
  resolutionStrategy.eachDependency { DependencyResolveDetails details ->
    if (details.requested.group == 'org.apache.tomcat.embed') {
        details.useVersion '8.0.3'
    }
  }
}

We could add some support for version properties to the Spring Boot Gradle plugin (feel free to open an issue in github) but it would probably have to be optional.
