Cobertura: Error reading file, multi module project

[Daniel Wood-4]

Some parts of this message have been removed. Learn more about Nabble's security policy.

I’m getting a strange Cobertura error for two modules in a multi module maven project. I’m using Sonar v1.11.1 and the build is executed by Hudson (1.328).

 

[ERROR] Cobertura: Error reading file /opt/Java/hudson/jobs/Sonar/workspace/<XXX>/target/cobertura/cobertura.ser: null

Error: Unable to read from data file /opt/Java/hudson/jobs/Sonar/workspace/<XXX>/target/cobertura/cobertura.ser

 

[ERROR] Error in Cobertura Report generation: Unable to generate Cobertura Report for project.

org.apache.maven.plugin.MojoExecutionException: Unable to generate Cobertura Report for project.

 

I believe indicates that the Cobertura.ser is empty and doesn’t have any instrumentation data in it. However when mvn cobertura:cobertura is executed from the command line, cobertura reports are generated correctly for each module of the project (including the two that fail when called by Sonar/Hudson).

One of the failing modules is packaged as a war, the other is packaged as an ejb. Again there are other ejb & war packaged modules in this project and they are instrumented correctly.

 

Any ideas?

 

Thanks,

Daniel

Hi Daniel,

There is a similar open bug on the Maven Cobertura plugin (http://jira.codehaus.org/browse/MCOBERTURA-91) but I haven't already met this bug with Sonar. Could you provide the full stack trace of your error log ?

Thanks

Hi Daniel,

I've analyzed the log file you sent me off list. I've still a couple of question :

- Do you always get this error on the two Maven modules or does it occur randomly ?

- Even if the error occurs, do you see a file cobertura.ser in the /opt/Java/hudson/jobs/Sonar/workspace/xxxx/target/cobertura/ directory ?

- How many classes do those maven modules contain ?

Thanks

Hi Freddy, the error always happens on the same two modules. And the cobertura.ser is created in the relevant directory. For the two modules that have this problem they have 30/60 classes in each.

 

Thanks,

Daniel

Hi Daniel,

Could you try the workaround provided by Wouter De Vaal on http://jira.codehaus.org/browse/SONAR-172 ?

For that, you need to update you pom.xml in order to add the following lines :

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-surefire-plugin</artifactId>

<version>2.4.3</version>

<configuration>

<systemProperties>

<property>

<name>cobertura.use.java.nio</name>

<value>false</value>

</property>

</systemProperties>

</configuration>

</plugin>

Hope it helps,

Freddy

Argh... I can't manage to understand why you don't get the error when you directly launch mvn cobertura:cobertura.

Which version of Maven do you use and if you use a version 2.0.X, could you try with Maven 2.2.X ?

Thanks for your help Daniel,

Hi Freddy,

 

I’ve been reviewing the environment where this issue occurs and it turns out that the JDK version has been switched back to the environments default, ie an IBM JDK.

Keeping the maven version as it was (2.0.10) and adding your recommended surefire change back into the pom, everything now works when executed from the Sun JDK.

 

Thanks for all your help and support on this.

Daniel

Argh... I can't manage to understand why you don't get the error when you directly launch mvn cobertura:cobertura.

 

Which version of Maven do you use and if you use a version 2.0.X, could you try with Maven 2.2.X ?

 

Thanks for your help Daniel,

Freddy

Hi Daniel,

 

Could you try the workaround provided by Wouter De Vaal on http://jira.codehaus.org/browse/SONAR-172 ?

 

For that, you need to update you pom.xml in order to add the following lines :

 

<plugin>

            <groupId>org.apache.maven.plugins</groupId>

            <artifactId>maven-surefire-plugin</artifactId>

            <version>2.4.3</version>

            <configuration>

                        <systemProperties>

                                    <property>

                                                <name>cobertura.use.java.nio</name>

                                                <value>false</value>

                                    </property>

                        </systemProperties>

            </configuration>

</plugin>

Hope it helps,

Freddy

Hi Daniel,

 

I've analyzed the log file you sent me off list. I've still a couple of question :

 

- Do you always get this error on the two Maven modules or does it occur randomly ?

- Even if the error occurs, do you see a file cobertura.ser in the /opt/Java/hudson/jobs/Sonar/workspace/xxxx/target/cobertura/ directory ?

- How many classes do those maven modules contain ?

 

Thanks

Freddy

I believe indicates that the Cobertura.ser is empty and doesn’t have any instrumentation data in it. However when mvn cobertura:cobertura is executed from the command line, cobertura reports are generated correctly for each module of the project (including the two that fail when called by Sonar/Hudson).

One of the failing modules is packaged as a war, the other is packaged as an ejb. Again there are other ejb & war packaged modules in this project and they are instrumented correctly.

 

Any ideas?

Hi,

I have the same problem with sonar 1.11.1. I had to downgrade to version 1.10.1. I am using JVM IBM also on AIX.

Freddy, is there any possibility to get Cobertura running on  sonar 1.11.1 using JDK IBM ?

Thank you

Hi Dali,

The only difference between Sonar 1.10 and Sonar 1.11 concerning Cobertura is :

http://jira.codehaus.org/browse/SONAR-1055

With this ticket Maven Cobertura 2.2 is no more used  even if it is specified in the Maven pom. I've done a quick search to find any known issues about Maven Cobertura 2.3 or Cobertura 1.9 with JDK IBM but I haven't found anything :-(

What would be great is to launch Maven in debug mode with IBM JDK, to attach to it remotely for instance with Eclipse or Netbeans to see exactly where and what root exception is thrown in Cobertura source code.

regards,

Freddy

Hi Daniel,

 

Could you try the workaround provided by Wouter De Vaal on http://jira.codehaus.org/browse/SONAR-172 ?

 

For that, you need to update you pom.xml in order to add the following lines :

 

<plugin>

            <groupId>org.apache.maven.plugins</groupId>

            <artifactId>maven-surefire-plugin</artifactId>

            <version>2.4.3</version>

            <configuration>

                        <systemProperties>

                                    <property>

                                                <name>cobertura.use.java.nio</name>

                                                <value>false</value>

                                    </property>

                        </systemProperties>

            </configuration>

</plugin>

Hope it helps,

Freddy

Hi Freddy, the error always happens on the same two modules. And the cobertura.ser is created in the relevant directory. For the two modules that have this problem they have 30/60 classes in each.

Hi Daniel,

 

I've analyzed the log file you sent me off list. I've still a couple of question :

 

- Do you always get this error on the two Maven modules or does it occur randomly ?

- Even if the error occurs, do you see a file cobertura.ser in the /opt/Java/hudson/jobs/Sonar/workspace/xxxx/target/cobertura/ directory ?

- How many classes do those maven modules contain ?

 

Thanks

Freddy

There is a similar open bug on the Maven Cobertura plugin (http://jira.codehaus.org/browse/MCOBERTURA-91) but I haven't already met this bug with Sonar. Could you provide the full stack trace of your error log ?

I believe indicates that the Cobertura.ser is empty and doesn’t have any instrumentation data in it. However when mvn cobertura:cobertura is executed from the command line, cobertura reports are generated correctly for each module of the project (including the two that fail when called by Sonar/Hudson).

One of the failing modules is packaged as a war, the other is packaged as an ejb. Again there are other ejb & war packaged modules in this project and they are instrumented correctly.

 

Any ideas?

 

Thanks,

Daniel

Hi Dali,

I've double-checked the difference between Sonar 1.10 and Sonar 1.11 and the only difference is that Sonar is no more using the Maven Cobertura version specified in the pom.xml file. Could you confirm that the use of version 2.2 of the Maven Cobertura plugin is specified somewhere in your pom file or parent pom ?

Thanks

Freddy

I tested sonar cobertura plugin of sonar 1.10.1 on sonar 1.11.1 (I modified the file parent-20091130120007.pom in local repository inside /org/codehaus/sonar/runtime/plugins/parent/ ) and I got the right result of cobertura. So now it is running.

 

I wish this gives you some hints.

Hi Dali,

 

The only difference between Sonar 1.10 and Sonar 1.11 concerning Cobertura is :

 

http://jira.codehaus.org/browse/SONAR-1055

 

With this ticket Maven Cobertura 2.2 is no more used  even if it is specified in the Maven pom. I've done a quick search to find any known issues about Maven Cobertura 2.3 or Cobertura 1.9 with JDK IBM but I haven't found anything :-(

 

What would be great is to launch Maven in debug mode with IBM JDK, to attach to it remotely for instance with Eclipse or Netbeans to see exactly where and what root exception is thrown in Cobertura source code.

 

regards,

Freddy

Keeping the maven version as it was (2.0.10) and adding your recommended surefire change back into the pom, everything now works when executed from the Sun JDK.

 

Thanks for all your help and support on this.

Argh... I can't manage to understand why you don't get the error when you directly launch mvn cobertura:cobertura.

 

Which version of Maven do you use and if you use a version 2.0.X, could you try with Maven 2.2.X ?

 

Thanks for your help Daniel,
