title: Apache PDFBox cannot find class 'Loader'. Why?
body: <p>I'm using either <strong>pdfbox-app-2.0.18.jar</strong> or <strong>pdfbox-app-2.0.17.jar</strong>.</p>
  <p>From the example <a href="https://svn.apache.org/viewvc/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/signature/CreateVisibleSignature.java?view=markup&amp;sortby=date" rel="noreferrer">here</a>, I have this code below :</p>
  <pre><code>try (FileOutputStream fos = new FileOutputStream(signedFile);
       PDDocument doc = Loader.loadPDF(inputFile)) {
      
       // code
  
  }
  </code></pre>
  <p>After executing this code, I'm getting this error given below :</p>
  <pre><code>org.apache.pdfbox.Loader is not found 
  </code></pre>
  <p>How to resolve this issue ?</p>
