Maven doesn't copy empty directories to webapps folder while creating war file

Question

I have he following structure of a maven web application

When I execute mvn install command it's creating war file but if you will look in target directory/sureportal you can easily see that lots of sub folders inside webapps directory are missing. What is wrong?

pom.xml file

<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">

  <groupId>com.nokia</groupId>
  <artifactId>sureportal</artifactId>
  <packaging>war</packaging>
  <version>1.0.0</version>
  <name>sureportal Maven Webapp</name>
  <url>http://maven.apache.org</url>
  <dependencies>

  </dependencies>
  <build>

  </build>
</project>

You can have a maven-war-plugin and configure to include empty folders.

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

exactly the same solution as mine. See the comments in my POM fragment ... but no problem – JimHawkins Aug 25 '16 at 10:22

In addition to the answer of sbaitmangalkar, insert the maven-war-plugin to the build section of your POM:

<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>

This tells the build process explicitly what to do.

This should not be required by default. – Saif Asif Aug 25 '16 at 07:06
@SaifAsif what you say sounds coorect. But without this section, in my project there is the same issue as reported by Subodh Joshi – JimHawkins Aug 25 '16 at 07:09
What about if the folder which is not copying when creating war is empty even then maven will copy the folders? – Subodh Joshi Aug 25 '16 at 07:20
yes, if you insert `true` like I did in my answer, even empty folders will be copied – JimHawkins Aug 25 '16 at 07:23
Ok do you mean like this -> http://stackoverflow.com/questions/2605747/maven-how-to-include-empty-directories But this will work for resource directory not for other – Subodh Joshi Aug 25 '16 at 09:51
@SubodhJoshi - you've written _"Can you please add this in to your question"_ . There is no question of mine. – JimHawkins Aug 25 '16 at 09:54
@JimHawkins Sorry i added another comment – Subodh Joshi Aug 25 '16 at 09:55
in my test project, this worked : `true` , not only for eresource folders – JimHawkins Aug 25 '16 at 09:56
This will work for `resource` directory not others and you need `resource` plugin in your pom.xml file. – Subodh Joshi Aug 25 '16 at 10:16

Try running mvn clean install. This will clear your compiled files first and ensures that all of it is compiled from scratch. Please check this thread for more details how-is-mvn-clean-install-different-from-mvn-install

Good luck.
