  <p>when trying to build my application with maven using <strong>mvn install</strong>
  i am getting the following error:</p>
  
  <pre><code>package org.hibernate.validator.constraints does not exist
  cannot find symbol symbol  : class NotBlank
  </code></pre>
  
  <p>here's my <strong>.classpath</strong> file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;classpath&gt;
      &lt;classpathentry kind="src" output="target/classes" path="src/main/java"/&gt;
      &lt;classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources"/&gt;
      &lt;classpathentry kind="src" output="target/test-classes" path="src/test/java"/&gt;
      &lt;classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6"/&gt;
      &lt;classpathentry kind="con" path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER"/&gt;
      &lt;classpathentry kind="output" path="target/classes"/&gt;
  &lt;/classpath&gt;
  </code></pre>
  
  <p>although there's no errors in eclipse.
  please advise.</p>
