Maven不包括空目錄複製到web應用文件夾在創建war文件

Question

我有他下一個Maven Web應用程序的結構

當我執行mvn install命令它創建war文件，但如果你會看在target directory/sureportal中，您可以很容易地看到webapps目錄中的大量子文件夾丟失。哪裏不對？

pom.xml文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    <artifactId>sureportal</artifactId> 
    <packaging>war</packaging>

</project> 

Answer 1

您可以有一個maven-war-plugin並配置爲包含空文件夾。

<plugin> 
    <artifactId>maven-war-plugin</artifactId> 
    <version>2.4</version> 
    <configuration> 
    <includeEmptyDirectories>true</includeEmptyDirectories> 
    </configuration> 
</plugin> 

Answer 2

嘗試運行mvn clean install。這將首先清除你編譯的文件，並確保它從頭開始編譯。請檢查這個線程的更多細節how-is-mvn-clean-install-different-from-mvn-install

祝你好運。

Answer 3

除了sbaitmangalkar的回答，插入maven-war-plugin到你的POM的構建部分：

<build> 
    <plugins> 
     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-war-plugin</artifactId> 
      <version>2.6</version> 
      <configuration> 
       <!- if you don't have a web.xml, otherwise "true" --> 
       <failOnMissingWebXml>false</failOnMissingWebXml> 
       <includeEmptyDirectories>true</includeEmptyDirectories> 
       <includes>**/*</includes> 

       <!-- if want your web files to be filterd --> 
       <webResources> 
        <resource> 
         <directory>src/main/webapp</directory> 
         <includes> 
          <include>**/*</include> 
         </includes> 
         <filtering>true</filtering> 
        </resource> 
        <resource> 
         <directory>src/main/resources/META-INF</directory> 

         <!-- only if needed in your project --> 
         <targetPath>/META-INF</targetPath> 
         <includes> 
          <include>context.xml</include> 
         </includes> 
         <filtering>true</filtering> 
        </resource> 
       </webResources> 

      </configuration> 
     </plugin> 
    </plugins> 
</build> 

這告訴構建過程做什麼明確。
