I need to obtain just one MultiPolygon as the combination
(dissolve/merge) of those in SimpleFeatureCollection.

I hope so, I am using this maven configuration:
...
<!-- === Versions of used frameworks and libraries === -->
<properties>
...
<org.geotools.version>8.0-M1</org.geotools.version>
...
</properties>
<repositories>
<repository>
<id>OSGEO GeoTools repo</id>
<url>http://download.osgeo.org/webdav/geotools</url>
</repository>
...
</repositories>
Is the right repository for the latest artifacts?
