Aled Sage commented on BROOKLYN-158:
------------------------------------
The workaround suggested (to comment out the dependencyConvergence) no longer
works. The results it gives is a coverage of 1.0 for everything!
It seems that cobertura-maven-plugin requires Java 6 [1], whereas we are now
using Java 7. However, [2] suggests that it can work with Java 7.
Do we need to just change the configuration (or cobertura versions), or do we
need to switch to a different tool such as JaCoCo [3] or perhaps one of the
others mentioned in [4].

> Project: Brooklyn
> Issue Type: Bug
> Affects Versions: 0.8.0-SNAPSHOT
> Reporter: Aled Sage
>
> When building Brooklyn with `mvn clean install -PCoverage`, it fails in the
> maven-enforcer-plugin due to the dependencyConvergence rule.
> The workaround is to comment out the dependencyConvergence rule in the
> maven-enforcer-plugin plugin, in the parent/pom.xml.
> The Coverage profile pulls in:
> {noformat}
> <dependency>
> <groupId>org.codehaus.mojo</groupId>
> <artifactId>cobertura-maven-plugin</artifactId>
> <version>${cobertura.plugin.version}</version>
> <scope>test</scope>
> </dependency>
> {noformat}
> The error is things like that below (plus another couple of hundred lines of
> this).
