title: git.properties is not visible for spring boot autoconfigure
body: <p>I use gradle plugin to generate <code>git.properties</code>:</p>
  
  <pre><code>id 'com.gorylenko.gradle-git-properties' version '2.2.0'
  </code></pre>
  
  <p>It generates</p>
  
  <pre><code>/resources/main/git.properties
  </code></pre>
  
  <p>However when <code>GitResourceAvailableCondition</code> is evaluated in <code>spring-boot-autoconfigure</code> then</p>
  
  <p><code>ResourceLoader</code> indicates that <code>classpath:git.properties</code> does not exist.</p>
  
  <p>How I can point to my resource in order to make it visible?</p>
