Question

Is there any maven plugin which will be invoking already existing rest web service? or else is there any way to invoke a web service in pom.xml. like we have for invoking a external command org.codehaus.mojo exec-maven-plugin 1.2 please help me

If you need invoke a REST service using a POST method, you can use a groovy script
