title: Error in Maven build: mvn.bat not recognized
body: <p>While trying to build a Java project under NetBeans (with an external Maven configured), I got the following error:</p>
  
  <blockquote>
    <p>"C:\Users......\bin\mvn.bat"" is not recognized as an internal or external command, operable program or batch file"</p>
  </blockquote>
  
  <p><strong>Edit</strong>: Using Maven 3.3.3, Windows 10;
  Added custom maven to NetBeans under Tools > Options > Java > Maven > Execution > Maven Home > Browse</p>
  
  <p>What can I do?</p>
