理由を教えてください。

パッケージング時にWEB-INF/フォルダにweb.xmlファイルが見つかりませんでした。

回避策

WEB-INF/web.xml ファイルが存在する場合は、pom.xml ファイルに <build> ノードに、maven-war-pluginのプラグイン設定を追加します。

org.apache.maven.plugins  
        
maven-war-plugin  
        
3.0.0  
        
WebContent  
                  
              
          
      
  

WebContent/WEB-INF/web.xml ファイルが存在しない場合、以下のように設定します。

org.apache.maven.plugins  
        
maven-war-plugin  
        
3.0.0  
        
false
