title: the "build automatically" and maven in Eclipse
body: <p>in Eclipse, when Maven is enabled, there is a pom.xml file to build with Maven. And also, Eclipse has a "build automatically" option in it's project menu.</p>
  
  <p>Is the "build automatically" automatically build with Maven, or we need uncheck it, because when Maven is enabled, we don't need the Eclipse build in build system anymore?</p>
