title: how to replace placeholder from a source file.properties to another file.properties with Maven
body: <p>I'm learning how to replace placeholder of a file properties to another file properties with Maven. My project has a main folder named testMaven and I have created two files properties in the project, where the first file is situated in testMaven->local->value.properties and into the file there are: </p>
  
  <p>user=testUser
  password=testPassword</p>
  
  <p>instead the second file properties situated into src/main/java->test.properties there are:</p>
  
  <p>user=@user@
  password=@password@</p>
  
  <p>I would like to have into the file Jar a file properties with the fields replaced with:
  user=testUser
  password=testpassword</p>
  
  <p>How do I write in the file pom.xml to do the description above?
  Thanks </p>
