title: Graddle-wrapper distributionUrl doesn't change
body: <p>I use a graddle-wrapper in my project. I fixed the distributionURL manually:</p>
  
  <p><code>distributionUrl=https://privateRepo/gradle-2.10-bin.zip</code></p>
  
  <p>I tried to change the variable manually (<code>distributionUrl=https://privateRepo/gradle-5.0-bin.zip</code>) but it keeps creating the first distributionURL after I run cordova build android.</p>
  
  <p>I don't get why it's still the first property.</p>
