I posted this at the tomcat plugin location here as well: [https://github.com/bmuschko/gradle-tomcat-plugin/issues/19](https://github.com/bmuschko/gradle-tomcat-plugin/issues/19)

We are using a Jersey web service in tomcat. When I start up “gradle tomcatRun” we always get this:

java.lang.ClassCastException: com.sun.jersey.spi.spring.container.servlet.SpringServlet cannot be cast to javax.servlet.Servlet

The problem appears to be this dependency:

compile(group: ‘com.sun.jersey’, name: ‘jersey-spring’, version: ‘1.11’), I am not sure how to solve this one…I saw a similar issue in the FAQ here: [https://github.com/bmuschko/gradle-tomcat-plugin](https://github.com/bmuschko/gradle-tomcat-plugin), however the solution suggested doesn’t solve the cast exception.

thanks for any thoughts.
