I want to know how to copy an entire directory into another directory using Maven without using the Mmaven antrun plugin.

You can use the Maven resources plugin.

As an example taken from their documentation:

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <artifactId>maven-resources-plugin</artifactId>
        <version>2.6</version>
        <executions>
          <execution>
            <id>copy-resources</id>
            <!-- here the phase you need -->
            <phase>validate</phase>
            <goals>
              <goal>copy-resources</goal>
            </goals>
            <configuration>
              <outputDirectory>${basedir}/target/extra-resources</outputDirectory>
              <resources>          
                <resource>
                  <directory>src/non-packaged-resources</directory>
                  <filtering>true</filtering>
                </resource>
              </resources>              
            </configuration>            
          </execution>
        </executions>
      </plugin>
    </plugins>
    ...
  </build>
  ...
</project>

This would copy the content of the directory into the outputDirectory if I'm not mistaken.

    `validate` did it for me, thank you! Now Maven runs copy-resources whenever I save any file in my project :) – Cardin Nov 06 '18 at 04:02

    Yes, but you're basically recreating the input directory as the output directory instead of "copy an entire directory into another directory". If I wanted to include another resource, it would need a whole other execution with its own outputDirectory – caduceus Jan 25 '21 at 08:25

You can use https://maven.apache.org/plugins/maven-dependency-plugin/examples/copying-artifacts.html

<?xml version="1.0" encoding="UTF-8"?>
<build>
   <plugins>
      <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-dependency-plugin</artifactId>
         <version>3.1.2</version>
         <executions>
            <execution>
               <id>copy</id>
               <phase>package</phase>
               <goals>
                  <goal>copy</goal>
               </goals>
            </execution>
         </executions>
         <configuration>
            <artifactItems>
               <artifactItem>
                  <groupId>junit</groupId>
                  <artifactId>junit</artifactId>
                  <version>3.8.1</version>
                  <type>jar</type>
                  <overWrite>false</overWrite>
           <outputDirectory>${project.build.directory}/alternateLocation</outputDirectory>
                  <destFileName>optional-new-name.jar</destFileName>
               </artifactItem>
            </artifactItems>
            <outputDirectory>${project.build.directory}/wars</outputDirectory>
            <overWriteReleases>false</overWriteReleases>
            <overWriteSnapshots>true</overWriteSnapshots>
         </configuration>
      </plugin>
   </plugins>
</build>
