Gradle issue - Trying to do some JAX-RS 2 with Jetty and Resteasy - ClassNotFoundException: javax.servlet.AsyncListener

Question

I use:

• Jetty 8.1.11
• Resteasy 3.0.1.Final
• Gradle 1.6 - jettyRun task - Running on windows 7 -> This is the culprit

Update: If I deploy my war directly in Jetty, it works fine, but if I start with the gradle jettyRun task, it fails. so it is related to Gradle

I get this stack:

And my gradle:

apply plugin: 'war'

apply plugin: 'jetty'

apply plugin: 'idea'


sourceCompatibility = 1.7
targetCompatibility = 1.7

def springVersion = "3.2.3.RELEASE"
def jaxrsVersion = "2.0"
def resteasyVersion = "3.0.1.Final"

group = 'com.test'
version = '1.0-SNAPSHOT'

...

dependencies {

    compile "org.jboss.resteasy:resteasy-jaxrs:$resteasyVersion"
    compile "org.jboss.resteasy:async-http-servlet-3.0:$resteasyVersion"
}

Web.xml:

           <url-pattern>/chat/*</url-pattern>
       </servlet-mapping>

</web-app>

I don't see what is missing and dit not find anything really related on the net.

Thank you

Gradle's Jetty plugin is based on Jetty 6, which doesn't support Servlet 3.0. You may want to look into the Arquillian Gradle plugin or Gradle Cargo plugin instead.
