Can't compile style.scss with sass-maven-plugin - eclipse

Question

I would like to use sass-maven-plugin to compile some SASS Template style.scss into css style.css. I have added the plugin to my pom.xml build.plugins as it is descriped here. My pom.xml looks like this:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<artifactId>tomcat7-maven-plugin</artifactId>

</plugin>
</plugins>
</pluginManagement>
</build>
</project>
I run the project with eclipse (right mouseclick on the project -> run as -> run Configuration -> and give as Goals : sass:update-stylesheets
eclipse prints the following error:
[ERROR] Failed to execute goal org.jasig.maven:sass-maven-plugin:1.1.0:update-stylesheets (default-cli) on project scss: The parameters 'resources' for goal org.jasig.maven:sass-maven-plugin:1.1.0:update-stylesheets are missing or invalid
What did I do wrong?

Answer 1

You need to add configuration to the plugin to tell it where the files to compile are and where to put the compiled files.
See resources in http://developer.jasig.org/projects/sass-maven-plugin/1.1.1/update-stylesheets-mojo.html
