title: Gradle does not point to specified version
body: <p>I am trying to upgrade the gradle wrapper version in my react-native android project.</p>
  
  <p>I did not install gradle globally in my Mac, I just use the wrapper that comes with react-native, it was version 2.14.1. I want to use a library and it requires gradle 4.4+ and I followed the official tutorial. Off the bat, I got this <a href="https://github.com/invertase/react-native-firebase/issues/1033#issuecomment-385271170" rel="nofollow noreferrer">Issue</a>.</p>
  
  <p>I found that whenever I type <code>./gradlew -v</code> it will always refer to the <code>/Users/rexlow/.gradle/wrapper/dists</code> in my user directory, although I already did specify that I want to use <code>gradle-4.4-all.zip</code> which is the newer version. The zip file is now in my project wrapper folder, (I followed this <a href="https://stackoverflow.com/a/27376432/9049053">thread</a>)</p>
  
  <p>As you can see from the image below, I tried to check for the gradle version but it will always show 2.14.1.</p>
  
  <p>Then, I tried deleting the 2.14.1 gradle folder from <code>/Users/rexlow/.gradle/wrapper/dists</code> and run the version checking command again, and for heaven sake, it went on and download the 2.14.1 version because the folder wasn't there.</p>
  
  <p>How can I altogether use a new gradle version in my project? Altering <code>gradle-wrapper.properties</code> does not work in my case. Let me know if you need to have a look at other files. </p>
  
  <p>Thanks!</p>
