If you install the camel-archetype-webconsole from the trunk (2.9-SNAPSHOT actually), and create a new project with it ("mvn archetype:generate -DarchetypeGroupId=org.apache.camel.archetypes -DarchetypeArtifactId=camel-archetype-webconsole -DarchetypeVersion=2.9-SNAPSHOT"), you can't run "mvn jetty:run".
There are conflicts with slf4j-api binding as you can see in the following logs
[main] ContextLoader ERROR Context initialization failed
Running "mvn dependencies:tree" show that two versions of slf4j are loaded.
You can find with this issue a patch that exclude slf4j for activemq-camel, which solve the problem.
But you then ran in the following problem
java.net.URISyntaxException: Illegal character in opaque part at index 22: jar:file:/mypath/.m2/repository/org/apache/camel/camel-web/2.9-SNAPSHOT/camel-web-2.9-SNAPSHOT.war!/WEB-INF/classes/
Which can be solved by updating jetty-version to a more recent one (7.5.3.v20111011) in the parent pom ( issue CAMEL-4544 with patch)
