web.xml is missing and is set to true

Question

Consider:

When I create a simple Maven project in Eclipse I am getting this error:

web.xml is missing and

Answer 1

Eclipse recognizes incorrect default webapp directory. Therefore we should set clearly it by maven-war-plugin.

  
    
      org.apache.maven.plugins
      maven-war-plugin
      3.0.0
      
        src/main/webapp
      
    
  

Once saving this setting, the error will never occour if removed it. (I cannot explain why.)
