title: Accessing Maven Pom Variables From Properties File
body: <p>I am developing a custom maven plugin. When I write:</p>
  
  <pre><code>${project.version}
  </code></pre>
  
  <p>into my pom file I can get its value however is there a way if I write into a properties file:</p>
  
  <pre><code>project.version = ${project.version}
  </code></pre>
  
  <p>that will set the project.version value correctly, how can I implement it at my Java code?</p>
  
  <p><strong>PS:</strong> I don't use annotations at my Mojo and I don't want to use variables at my Java code because user should define as my variables as at a properties file and I can not change my core Java code in order to changed things.</p>
