title: Proper way to install/run a gradle plugin from github (specifically the arquilian plugin)?
body: <p>I would like to use the arquillian plugin here to run jetty 8+:</p>
  
  <p><a href="https://github.com/aslakknutsen/arquillian-gradle-plugin" rel="noreferrer">https://github.com/aslakknutsen/arquillian-gradle-plugin</a></p>
  
  <p>If I put "apply plugin: 'arquillian'" in my gradle script, it does not find it.</p>
  
  <p>So I must have to install it somehow. I look for info on this, but did not find.</p>
  
  <p>Would you have a pointer on how to do that?</p>
  
  <p>I am using gradle 1.6 on windows.</p>

  <p><strong>Update</strong> after answer by @raeffs:
  I updated the gradle script with it and the build is successfull, but I don't see my war started after an arquillianRunJetty (port 8080 is not even listening).</p>
  
  <p>Then I tried to add what is indicated on the github page:</p>
  
  <pre><code>arquillian {
      debug = true
      deployable = file('my/path/arbitraryWebApp.war')
  
      containers {
          jetty {
              version = '8'
              type = 'embedded'
              config = ['bindHttpPort': 8080, 'bindAddress': '127.0.0.1', 'jettyPlus': false]
  
              dependencies {
                  adapter 'org.jboss.arquillian.container:arquillian-jetty-embedded-7:1.0.0.CR2'
                  container 'org.eclipse.jetty:jetty-webapp:8.1.11.v20130520'
                  container group: 'org.eclipse.jetty', name: 'jetty-plus', version: '8.1.11.v20130520'
              }
          }
  </code></pre>
  
  <p>I had to replace arquillian-jetty-embedded-7:1.0.0.CR2 with CR1 as it is not in maven central.</p>
  
  <p>Then I put the path to my war. When starting again, there is more chatter but still no listening on port 8080.</p>
  
  <p>So I still miss something.</p>
  
  <p>I also find awkward to have to reference with an absolute path for the war I am building with the gradle script. I think there could be a kind of self reference.</p>
  
  <p><strong>Update</strong>
  It is running fine now thanks to @raeffs. I don't really know what was wrong in my previous step.</p>
  
  <p>The path to the web app takes the name, plus the version.</p>
  
  <p>Thank you</p>
