To recreate do the following:
mvn archetype:create -DarchetypeGroupId=org.appfuse.archetypes -DarchetypeArtifactId=appfuse-basic-struts -DremoteRepositories=
http://static.appfuse.org/releases -DarchetypeVersion=2.0-rc1 -DgroupId=com.mycompany.myproject -DartifactId=myproject
mvn war:inplace
rm -r src/main/webapp/WEB-INF/lib/
rm src/main/webapp/WEB-INF/classes/struts.xml
mvn jetty:run
Adding struts.xml to warpathExcludes the section of maven-warpath-plugin of pom.xml fixes the problem. See attached patch.
