Actually I've found the error. It's to do with checkstyle, it should only apply to the source "jspwiki-war" and not to all the modules (especially not jspwiki-wikipages).
Find in pom.xml the section <plugin> <artifactId>maven-eclipse-plugin</artifactId> <version>2.9</version> <configuration> <downloadSources>true</downloadSources> <downloadJavadocs>true</downloadJavadocs> <additionalConfig> <file> <name>.checkstyle</name> <location>./src/main/config/dev/jspwiki-checkstyle.xml</location> </file> <file> <name>.settings/org.eclipse.jdt.core.prefs</name> <location>./src/main/config/dev/jspwiki-eclipse-codestyle.xml</location> </file> </additionalConfig> <additionalProjectnatures> <projectnature>net.sourceforge.metrics.nature</projectnature> <projectnature>net.sf.eclipsecs.core.CheckstyleNature</projectnature> </additionalProjectnatures> </configuration> </plugin> Cut this and move it to jspwiki-war/pom.mxl anywhere within <build>/<plugins>. Note: I've changed the location path to remove "jspwiki-war", as this is now part of the "basedir" That should fix it. Someone should make this change to the svn source!
