The following example shows how to do this in your pom.xml:
<project> [...] <build> [...] <plugins> [...] <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <version>2.10</version> <configuration> <additionalProjectFacets> <jst.jsf>1.1<jst.jsf> <jst.ejb.xdoclet>1.2.3</jst.ejb.xdoclet> <jst.web.xdoclet>1.2.3</jst.web.xdoclet> </additionalProjectFacets> </configuration> </plugin> [...] </plugins> [...] </build> [...] </project>
