Multi-module project by Maven and Jenkins

I have the following projects organized in a flat structured way:

parentProject
+-pom.xml

projectWeb <depends on libraryA and libraryB>
+-pom.xml

libraryA
+-pom.xml

libraryB
+-pom.xml

In pom.xml, inside the parent project, there are links to other modules and it is used to inherit and manage dependencyManagement, here is a snippet:

<project>
    ....
    <modules>
        <module>../projectWeb</module>
        <module>../libraryA</module>
        <module>../libraryB</module>
    </modules>
    <dependencyManagement>
    ...
    </dependencyManagement>
    <build>
    ...
    </build>
    ....
</project>

In Jenkins , I have one maven job for each project, and it works fine when I create parentProject, i.e. builds each project specified in the section modules. The problem that I encountered when I pass the SVN change to libraryA, I would expect that after creating library A, a restart will occur projectWeb, but this did not happen. Does anyone know what I'm doing wrong?

Thanks in advance.

EDIT

modules parentProject\pom.xml, , pom.
