Using lesscss-maven-plugin in Eclipse (with m2e)

[DenisGL]

Hello,
I've tried to use your (wonderfull) plugin from within Eclipse (with m2e), but nothing happens : no css file is generated.
Could you provide a kind of how-to for using this plugin in Eclipse ?
Thanks a lot.

Here are the relevant portions of my pom.xml:

    <properties>
        <lesscss.outputDirectory>${project.build.directory}/${project.build.finalName}/styles</lesscss.outputDirectory>
    </properties>

                <executions>
                    <execution>

                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

Hi i tried this, but when cleaning my project the less file is not compiled to m2e-wtp\web-resources\resources\css until i change anything in my .less file

i'm using eclipse neo

[Aldaviva]

Maybe changing the plugin execution phase from process-sources to a different phase would help?

[wutzebaer]

Hm did not help, it seams that the compile goal is not called at all when i change the "sourceDirectory" do anything invalid i get an error in my pom.xml, but after a clean the error diappears... but this source tells that compile should beexecuted: http://stackoverflow.com/questions/2632425/how-do-i-start-maven-compile-goal-on-save-in-eclipse#2633133 when saving the pom or my less file againt the arror re-appears
