Now, I'd like to create an EclipseSW external tool configuration to perform a deploy of a selected project using the tomcatSW mavenSW plugin. To do so, I first perform a "clean" phase to clean the selected project. After this I perform the "tomcat:deploy" goal to build and deploy the warW file.

Name:mvn clean tomcat~deploy
Working Directory:${project_loc}
Arguments:clean tomcat:deploy

The external tool configuration is shown here.

'mvn clean tomcat~deploy' External Tool Configuration

I selected the "mywebapp" project in my Eclipse Navigator view and then ran the external tool that we just created. It generated the following console output:

Console output from 'mvn clean tomcat:deploy'

In the Tomcat Manager, if I click the "List Applications" link, the "mywebapp" application appears at the bottom of the list.

Tomcat Manager - mywebapp now appears

The "mywebapp" war file was successfully deployed to Tomcat using the tomcat maven plugin. Although not shown here, if I try hitting my test servletW in the "mywebapp" application running on Tomcat, it succeeds.
