Ignoring report generation for specific classes in cobertura maven plugin

Question

I've been using Cobertura plugin for report generation and instrumentation (with surefire). Here is the issue I am facing:

I am unable to make the plugin ignore report generation for specific classes in my project.

PF below the related excerpt from pom.xml, I have added the ignore tag, but that just ignores instrumentation for the ignored classes.

I want the report for specific projects to not be generated at all.

Firstly, due to my limited knowledge of both Maven and Conberture, I want to know is it possible, and if yes, then what are the changes I need to get done in pom.xml.

pom.xml

<report>
    <!-- other plugins exist but are not important to be listed here I guess -->   
    <plugin>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
            <skipTests>false</skipTests>
            <systemProperties>
                <property>
                <name>net.sourceforge.cobertura.datafile</name>
                <value>target/cobertura/cobertura.ser</value>
                </property>
            </systemProperties>
        </configuration>
    </plugin>
    <!-- The following is the plugin for cobertura, which takes care of integration and report generation-->
    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>cobertura-maven-plugin</artifactId>
        <configuration>
            <check>
                <branchRate>50</branchRate>
                <lineRate>50</lineRate>
                <haltOnFailure>true</haltOnFailure>
                <totalBranchRate>50</totalBranchRate>
                <totalLineRate>50</totalLineRate>
                <packageLineRate>50</packageLineRate>
                <packageBranchRate>50</packageBranchRate>
            </check>
            <instrumentation>
                <ignores>
                  <ignore>deshaw.dportal.alert.*</ignore>
                  <ignore>deshaw.dportal.atc.*</ignore>
                  <ignore>deshaw.dportal.basket.*</ignore>
                  <ignore>deshaw.dportal.fcs.*</ignore>
                  <ignore>deshaw.dportal.event.*</ignore>
                  <ignore>deshaw.dportal.filings.*</ignore>
                  <ignore>deshaw.dportal.glg.*</ignore>
                  <ignore>deshaw.dportal.icp.*</ignore>
                </ignores>
            </instrumentation>
        </configuration>
    </plugin>
</report>

Edit:

This my directory structure:

module
|
|-apps
|    |-alert
|    |    |-src
|    |    |-target
|    |    |-pom.xml
|    |-------------------
|    |-company
|    |    |-src
|    |    |-target
|    |    |-pom.xml
|-----------------------
|-jobs
|    |-job1
|    |    |-src
|    |    |-target
|    |    |-pom.xml
|    |-job2
|    |    |-src
|    |    |-target
|    |    |-pom.xml

I tried the following in module/pom.xml

<instrumentation>
    <excludes>
        <exclude>**/apps/*.*</exclude>
    </excludes>
</instrumentation>

I still get the reports being generated in both the alerts and company directory.

Probably the exclude regex is not right?

Cobertura maven plugin does not respect exclusion and ignoring for report generation.It does so for instrumentation though.
