---------------------------------------------
Benson, what is the change we should do to make cobertura work with M3 ?
> forkMode is ignored when generating cobertura reports using Maven 3

> Key: MCOBERTURA-132
> URL: http://jira.codehaus.org/browse/MCOBERTURA-132
> Project: Maven 2.x Cobertura Plugin
> Issue Type: Bug
> Environment: Maven 3, Windows
> Reporter: Firass Shehadeh
> Assignee: Benson Margulies
> Fix For: 2.6
>
>
> I am evaluating upgrading my projects to use Maven 3.x, and I started to
> notice that some of my unit tests are failing when run as part of Cobertura,
> even though the same tests would pass without issues when they run under the
> regular "test" or "surefire" phases. It turns out that some of my tests have
> some depend on some static setup, so they would require to be run in separate
> JVMs, and this is usually accomplished by using <forkMode>always</forkMode>
> as part of the configuration of the surefire plugin. This worked fine with
> earlier versions of Maven, but started to break when trying Maven 3.x.
> To verify the issue, I ran the same "mvn site" command twice on the same POM,
> with different versions of Maven, and here is what I found out:
> - When using Maven 2.2.1, I can see that starting a new test will result in
> spawning a new JVM (I verified that using ProcessExplorer).
> - When using Maven 3.0, I can see that the same JVM is being reused across
> the different unit tests.
> Here are some of the relevant snippets from my POM:
> <!-- from the build part -->
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-surefire-plugin</artifactId>
> <version>2.6</version>
> <configuration>
> <forkMode>always</forkMode>
>
> <redirectTestOutputToFile>true</redirectTestOutputToFile>
> <includes>
> <include>**/*Test.java</include>
> </includes>
> </configuration>
> </plugin>
> <!-- from the reporting part -->
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-surefire-report-plugin</artifactId>
> <version>2.6</version>
> </plugin>
> <plugin>
> <groupId>org.codehaus.mojo</groupId>
> <artifactId>cobertura-maven-plugin</artifactId>
> <version>2.4</version>
> <configuration>
> <formats>
> <format>html</format>
> <format>xml</format>
> </formats>
> </configuration>
> </plugin>
> I suspect that this has to do with the way the surefire plugin is being
> called from Cobertura.
