jetty:run causes class not found exception for org.mortbay.jetty.webapp.WebAppContext

Question

Hi i have the following configuration.

<plugin>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>8.1.3.v20120416</version>
</plugin>

and in my jetty-env.xml I have

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">
<Configure class="org.mortbay.jetty.webapp.WebAppContext">
</Configure>

When i run with mvn jetty:run i get the following error.

How do i fix this?

Answer 1

I suspect you have a jetty-web.xml or some old jetty configuration files floating around

org.mortbay.jetty.webapp.WebAppContext = org.eclipse.jetty.webapp.WebAppContext

the packaging is different in jetty7 and 8 since we moved to the eclipse foundation a few years ago.
