I have this set, and everything working fine on a Windows box during tests, Deployment to unix box for testing, the folder is missing and is not created :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.3</version>
<configuration>
<includeEmptyDirs>true</includeEmptyDirs>
<!-- specify UTF-8, ISO-8859-1 or any other file encoding -->
<encoding>UTF-8</encoding>
</configuration>
</plugin>
Its location is conventional here:
src/main/resources/myfolder
It's deployed as a war, and the directory is not created in WEB-INF/classes.
The rest of my pom looks like this:
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
<resource>
<directory>src/main/resources/myfolder</directory>
</resource>
<resource>
<directory>src/main/webapp/WEB-INF</directory>
<filtering>true</filtering>
</resource>
</resources>
