Hi,
I'm using a configuration with two base projects; BaseJava and BaseEJB (extends BaseJava). I have configured the maven-site-plugin in the BaseJava like this: [BaseJava/pom.xml]: . <build> . <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-site-plugin</artifactId> <version>2.0-beta-7</version> <configuration> <outputDirectory>${outputDirectory}/site</outputDirectory> <inputEncoding>ISO-8859-1</inputEncoding> <outputEncoding>ISO-8859-1</outputEncoding> </configuration> </plugin> </plugins> . </build> . <reporting> When calling site:site in projects that extend BaseJava there is no problem, but when calling from projects that extend BaseEJB the site-plugin fails with an NPE: [WARNING] Unable to load parent project from repository: Failed to validate POM for project com.acme.product:BaseEJB at Artifact [com.acme.product:Bas eEJB:pom:1.0-SNAPSHOT] [DEBUG] Parent project loaded ...
