Maven Cobertura plugin not generating coverage.xml - maven-plugin

Question

I am trying to generate a coverage.xml so that I can reference it in Cobertura plugin of Hudson, but the file is not being created.
I've added the following to my POM
<reporting>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.5.1</version>
<configuration>
<formats>
<format>html</format>
<format>xml</format>
</formats>
</configuration>
</plugin>
</plugins>
</reporting>
After running mvn cobertura:cobertura, the HTML site is generated as expected at **\target\site\cobertura, but coverage.xml is nowhere to be found. What am I missing/misunderstanding?
I am running Maven 3.0.3

Answer 1

Add below lines to your application Goals:(configure section of the application in jenkins)
cobertura:cobertura -Dcobertura.report.format=xml
pom.xml changes:
<reporting>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.6</version>
<configuration>
<formats>
<format>html</format>
<format>xml</format>
</formats>
</configuration>
</plugin>
</plugins>

Answer 2

I put the plugin in the build section and it works:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.5.1</version>
<configuration>
<formats>
<format>html</format>
<format>xml</format>
</formats>
</configuration>
</plugin>
</plugins>
</build>
The reporting section and its differences to the plugin section are described here. I don't know if this is a maven [3.0.4] or cobertura-plugin issue.

Answer 3

I'm still quite a novice with the connections between Maven Plugins and Hudson and it's plugins - so this isn't an intelligent answer by any means, but help on Google is very few and far between for this issue - so hopefully it helps someone in the future.
After spending a few more hours of tinkering with settings, I've found that the coverage.xml simply doesn't seem to be built locally.
This is the combination that got it working:
I had changed my version to 2.2 in my POM (I was getting resource
not found errors from Apache with 2.5.1)
Added cobertura:cobertura in my Hudson goal
Set the Cobertura coverage pattern to the
recommended **/target/site/cobertura/coverage.xml

Answer 4

My objective was to get Cobertura to run duing mvn test with no additional command line parameters. Here's the magic XML that did the trick for me, with both the HTML and XML being generated in /target/site/cobertura.
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.7</version>
<executions>
<execution>
<id>cobertura</id>
<phase>test</phase>
<goals>
<goal>cobertura</goal>
</goals>
<configuration>
<formats>
<format>xml</format>
<format>html</format>
</formats>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>

Answer 5

I had the same issue but it's resolved right now:
Just add -Dcobertura.report.format=xml after your maven command. It should work

Answer 6

I have the same issue using 2.6 of the plugin.
I found that when I specify both types, I only got html.
<formats>
<format>html</format>
<format>xml</format>
</formats>
But when I specify only xml, I get an xml report.
<formats>
<format>xml</format>
</formats>
This is probably a bug in the plugin.
Another user suggested creating two executions. I tried that with no success (meaning I got html, but not xml).

Answer 7

Update your POM file as
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.7</version>
<configuration>
<formats>
<format>html</format>
<format>xml</format>
</formats>
</configuration>
</plugin>
</plugins>
This worked out for me: Probable reason it contanis the latest version of cobertura-maven-plugin (2.7)

Answer 8

The are two ways to integrate Cobertura into Maven.
Put Cobertura into the build section of the pom file, then you have to execute mvn clean cobertura:cobertura to generate the reports. If you have XML and HTML configured, then you get both reports.
Put Cobertura into the reporting section of the pom file, then you have to execute mvn clean site to generate the reports. If you have XML and HTML configured, then you get both reports. Additionally you get a generated site (open target/site/index.html) with all reports integrated e.g. Coberture, Checkstyle, ...
