Question

i am running on maven 2 and i am using the Apache Tomcat Maven Plugin for tomcat 7 with the following configuration:

<plugin>
  <groupId>org.apache.tomcat.maven</groupId>
  <artifactId>tomcat7-maven-plugin</artifactId>
  <version>2.0-beta-1</version>
    <configuration>
      <path>/${project.build.finalName}</path>
    </configuration>       
</plugin>

but when trying to run the application with mvn tomcat7:run i am getting the following exception:

SEVERE: Unable to determine URL for WEB-INF/classes

please advise how to fix this exception.

It seems that is a problem in the tomcat version bundled with the tomcat7-maven-plugin (which is fixed to 7.0.25). See this answer on a similar question.
