Exception occurs when running jetty with maven

Question

I'm trying to deploy and run my app to jetty with maven. Following is my configuration in pom.xml:

<plugin>
      <groupId>org.eclipse.jetty</groupId>
      <artifactId>jetty-maven-plugin</artifactId>
      <version>9.3.0.M2</version>
      <configuration>
         <war>${project.build.directory}/${project.build.finalName}.war</war>
       </configuration>
 </plugin>

But when I run mvn jetty:run-war , I have following exception in my console:

Anyone knows what's happening here?

Answer 1

You have to add cocoon-core-<Version>.jar jar to your classpath. This jar contains class org.apache.cocoon.servlet.DebugFilter wich is missing in your classpath.

Add:

<dependency>
    <groupId>org.apache.cocoon</groupId>
    <artifactId>cocoon-core</artifactId>
    <version>2.2.0</version>
</dependency>

to your pom file
