title: Syntax of the pom.xml scm connection string
body: <p>I'm cleaning up pom files in my project and find out I use two slightly different scm records:</p>
  
  <pre><code>&lt;scm&gt;
      &lt;connection&gt;scm:git:https://github.com/jadler-mocking/jadler.git&lt;/connection&gt;
      &lt;developerConnection&gt;scm:git:https://github.com/jadler-mocking/jadler.git&lt;/developerConnection&gt;
      &lt;url&gt;https://github.com/jadler-mocking/jadler&lt;/url&gt;
  &lt;/scm&gt;
  </code></pre>
  
  <p>vs</p>
  
  <pre><code>&lt;scm&gt;
      &lt;connection&gt;scm:git:git@github.com:jadler-mocking/jadler.git&lt;/connection&gt;
      &lt;developerConnection&gt;scm:git:git@github.com:jadler-mocking/jadler.git&lt;/developerConnection&gt;
      &lt;url&gt;https://github.com/jadler-mocking/jadler&lt;/url&gt;
  &lt;/scm&gt;
  </code></pre>
  
  <p>I haven't been able to find any resource describing the syntax of the connection strings so far. What is the difference between these two?</p>
