David Vicente commented on MOJO-749:
------------------------------------
i have found the problem.
In the getCoberturaDataFile( MavenProject project ) method,
i retreive all reports from project.getReportPlugins() method.
I iterate to find the cobertura plugin.
if in the pom.xml ( <reporting> section ) , you specify a version as :
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.1-SNAPSHOT</version>
</plugin>
it works fine.
but if you let maven using the last version as :
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
</plugin>
the ReportPlugin object has null value for version.
I will correct that as done in cobertura-maven-plugin without using the version
value of the plugin.
Correction will be commited this day 2007 May 11.
