body: <p>this issue is not the same as <a href="https://stackoverflow.com/questions/7557111/mybatis-3-0-5-and-mappers-loading-problem">MyBatis 3.0.5 and mappers loading problem</a> and <a href="https://stackoverflow.com/questions/2878309/how-to-suppress-maven-unable-to-find-resource-messages">How to suppress Maven &quot;Unable to find resource&quot; messages?</a></p>
  
  <p>i have xml files in org.org.wpse.db.config.db.config package, but why i cannot find these xml files in target/classes/org/wpse/db/config/ directory even after i run mvn compile.</p>
  
  <p>this error leads to the following faillure when i use mybatis:</p>
  
  <pre><code>Could not find resource
  </code></pre>
  
  <p>the issue which lead to this error is that the .xml files are not copied to the build dir, even i when i used mvn compile explicitly</p>
