PowerMock doesn't work correctly when using cobertura and Maven #21

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
There seems to be a problem with cobertura, Maven and PowerMock.

For example adding cobertura to the DocumentationExamples project results
in the following error message (on Linux as well after configuring surefire
with cobertura.use.java.nio to false): 

Cobertura: Loaded information on 5 classes.

We need to address this if possible.

There seems to be a work-around: 
  <build>
  <plugins>
     <plugin>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
            <forkMode>pertest</forkMode> 
        </configuration>
      </plugin>
     </plugins>
  </build>

The workaround is good enough for now

I don't think workaround is good enough. With the work around, I still get the
Unable to get lock on
/home/h_maf/hudson/data/jobs/mplus-services-applications/workspace/mplus_service
s/applications/routing/ServiceEndpointRouter/target/cobertura/cobertura.ser.lock
:
null
This is known to happen on Linux kernel 2.6.20.
Make sure cobertura.jar is in the root classpath of the jvm 
process running the instrumented code.  If the instrumented code 
is running in a web server, this means cobertura.jar should be in 
the web server's lib directory.
Don't put multiple copies of cobertura.jar in different WEB-INF/lib directories.
Only one classloader should load cobertura.  It should be the root classloader.

The workaround is not good enough since it slows our build down from 40s to 14
minutes!! Can someone unfix this issue and suggest a more appropriate solution?

I looked into it a year ago and I couldn't find any solution other than this. 
It's
quite a known problem if you google for it. If you have any ideas on how to 
solve
this please share them with us.
