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?

Answer 1

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

Known bug reported at : http://jira.codehaus.org/browse/MCOBERTURA-52

Answer 2

You can exclude classes from your cobertura report by moving the <plugin> block from the <reporting> block to your <build> block in your pom.xml.

Answer 3

I had a similar problem and found a very helpful tutorial: http://www.java-tutorial.ch/software-testing/maven-cobertura

The solution is quite close to the answer that rdvdijk posted. The plugin information should be in the build section as well as in the reporting section. But the exclude information should be placed in the build section of the pom.

Answer 4

Use excludes i.o. ignores.
This is how I exclude specific classes from cobertura:

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.4</version>
<configuration>
    <instrumentation>
        <excludes>
            <exclude>com/bnpp/ecom/**/*Test.class</exclude>
            <exclude>com/lrc/web/WicketApplication.class</exclude>
            <exclude>com/lrc/service/HeartBeatWebServiceMock.class</exclude>
        </excludes>
    </instrumentation>
</configuration>

Answer 5

I could successfully generate a cobertura coverage report by ignoring the *Test files from the project after changing the cobertura-maven-plugin version from 2.6 to 2.4 (as mentioned by Stjin geukens in the above comments).

Please find the complete maven plugin details below:

            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>cobertura-maven-plugin</artifactId>
                <version>2.4</version>
                <configuration>
                    <instrumentation>
                        <excludes>
                            <exclude>com/services/impl/*Test.class</exclude>
                            <exclude>com/exceptions/*Test.class</exclude>
                            <exclude>com/services/*Test.class</exclude>
                            <exclude>com/utils/*Test.class</exclude>
                        </excludes>
                    </instrumentation>
                </configuration>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>cobertura</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

P.S: I am not sure what is the issue with 2.6 version of the plugin
