title: Gradle template with mongodb and rabbitmq services
body: <p>I use GitLab with Gradle <a href="https://gitlab.tech.orange/Orange-OpenSource/tbc/gradle" rel="nofollow noreferrer">https://gitlab.tech.orange/Orange-OpenSource/tbc/gradle</a>.
  I'd like to use services mongodb and rabbitmq like with :</p>
  <pre><code>services:
    - name: mongo:latest
      alias: mongo
    - name: rabbitmq:3-management
      alias: rabbitmq
  </code></pre>
  <p>but: gitlab-ci-gradle.yml don't see services from .gitlab-ci.yml</p>
  <p>If I change directly in .gradle-base script (I've made a copy in my local dev) then it's ok.</p>
  <p>Is it possible to have a generic gradle script ?
  I'm not very good in gitlab script.</p>
  <p>Thanks</p>
