Running tomcat maven plugin in a multi modules project

[Sigmond Hola]

I have a multi-module project like this:

ROOT:pom
    --- web:war
    --- domain:jar
    --- service:jar
    --- dao:jar

And i configure tomcat7-maven-plugin in pom.xml of module *web *so that I
can using tomcat:run to run this web application.

But if I change something in other module, for example, add a new entity
class in module domain, I have to install the ROOT to local repo first
before I run tomcat:run within module web, otherwise a error: cannot find
symbol will be reported if I run tomcat:run directly.

So how can I install other modules first before I run tomcat:run within
module web if I change something in other modules?

Thanks in advance.

Best regards.
