Compiling LESS CSS with Maven and m2e-wtp - eclipse

Question

I'm trying to compile LESS CSS files with lesscss-maven-plugin, both in pure maven (with command line) and within Eclipse (Juno).
In the lesscss-maven-plugin, I need to define an output directory, but I noticed that in Eclipse WTP copies files from target/m2e-wtp in my server (JBoss), but that this directory is ignored by the war plugin of Maven.
I succeeded to reach my goal with Maven profiles : in Eclipse I use a m2e profile configured in Project settings, so I can define two different destination folders depending on I build in Eclipse or not.
Here is my pom.xml :
<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/xsd/maven-4.0.0.xsd">

</configuration>

</plugins>

<execution>
<goals>
<goal>compile</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
</profiles>
This works, but is there a better way to do this, without the profile trick ?

Answer 1

I found another solution with a different less compiler : wro4j. With this compiler, both exists maven and m2e plugins.
In addition, a tutorial (for building boostrap) can be found here: m2e-wro4j

Answer 2

The same solution you provided, a bit cleaner :

The m2e profile is activated with a m2e variable, so you don't have to select it.
