Building Multiple eclipse Project with Maven

I have configured Multiple project in my eclipse workspace and each project has its own POM.XML . I have worked with the dependencies with single eclipse project with multiple modules in that single project and it works fine when build with Maven but when working with Different projects is there any possibility to build the all the project with one single parent project? I do not want to build all the dependent project and install the JAR in local repository and than build the parent project I know that will work fine. What I want to achieve is with out building the dependent project I will just build the Parent Project and it will build all the dependent project plus all the Third party JAR's which every project is having and put it into the local repo and every project's respective target directory.

The project structure in eclipse is like this

C:\eclipse\workspace
\ ProjectA

pom.xml

src.com.javasource

\ ProjectB (Child)

pom.xml

src.com.javasource

\ ProjectC

pom.xml

src.com.javasource

So when I will compile or run the command on ProjectA 's pom.xml it should build the ProjectB and ProjectC and create the projectb.jar and projectc.jar and put those jar's into the respective projects target directory.
