Nullpointer in FlexCpdMavenSensor.java:152

Forgot to include the link in the description, followed instructions mentioned here:

• http://docs.codehaus.org/display/SONAR/Sonar+Flex+Plugin

Found some more information:

• target/cpd.html is 0 bytes
• am able to run mvn -e com.adobe.ac:flex-pmd-cpd-maven-plugin:1.0:check from the project without errors.

FlexCPD does not like something in our project...

And more, after enabling debug on the sonar execution:

[INFO]  Configure maven plugins...
[DEBUG]  Configure org.sonar.plugins.flex.cpd.FlexCpdMavenPluginHandler@bc5918...
[DEBUG]  Configure org.sonar.plugins.flex.flexmetrics.FlexMetricsMavenPluginHandler@17d414a...
[DEBUG]  Configure org.sonar.plugins.flex.flexpmd.FlexPmdMavenPluginHandler@498f2c...
[INFO]  Code duplications are not checked on language Flex.
[DEBUG]  Sensors : FlexSourceImporter -> AsynchronousMeasuresSensor -> org.sonar.plugins.flex.cpd.FlexCpdMavenSensor@c7e691 -> FlexMetricsSensor -> FlexPmdSensor -> FlexSquidSensor -> ProfileSensor -> ProjectLinksSensor -> VersionEventsSensor -> Maven dependencies

The line "Code duplications are not checked on language Flex." would be a good explanation of why CPD is 0 bytes... CPD is just not being triggered for language "flex..." ? Not sure how or where this is configured however.

Kyle, 2 points and a question :
1. the sonar plugin checks cpd.xml and not cpd.html.
2. "Code duplications are not checked on language Flex" is misleading. It actually only means that duplications are not being calculated by the core mechanism of Sonar. This is indeed computed by flexcpd
3. when you run mvn -e com.adobe.ac:flex-pmd-cpd-maven-plugin:1.0:check, is cpd.xml empty ?

Hey Olivier - thanks for the response.

1. I thought so - more of an observation.
2. This was where I thought the problem would be. cpd.xml is not present - because it did not run. I checked out the source tree for Sonar and noticed CpdSensor accepts mappings, and if the flex mapping does not exist - cpd would not run. Of course - I defer to your expertise, it's just where my troubleshooting led me
3. Running "mvn -e com.adobe.ac:flex-pmd-cpd-maven-plugin:1.0:check" works and outputs cpd.xml. cpd.html is still 0 bytes after this run, so I agree cpd.html being 0 bytes should not be related to this problem.

Investigated further:

• cpd.xml is in fact being generated OK - so this is not the issue
• Narrowed it down to the following section where a NullPointerException is thrown:
  • ClassDuplicationData.cumulate(
  • context.getResource(targetResource).getEffectiveKey()
• It seems a class is never making it into the SensorContext provided to the plugin.

Any idea what next steps I should look for? Any debug logging for SensorContext? Any help is greatly appreciated.

Can you attach your cpd.xml file ?

Attached the cpd.xml. The NullPointer appears when it gets to:

com.gp.srs.view.components.gridDetails.GridDetailsComponent

At first glance I can't really find anything wrong with the cpd.xml.

Thanks,

I've tested it out on another project of ours, and running into the same issue at the same spot. I will see if there are any similarities between the 2 situations. Do you want to see this cpd.xml as well?

I think it might actually come from mxml files that are not managed properly but I need to do a test. Can we swtch to the dev mailing list to carry on this ? Would be easier for me.

I have identified the issue and will fix it tomorrow

Hey great! I'd be curious about the root cause. Thanks!

Root cause is : FlexCPD analyzes MXML files, and Sonar does not !
I have added a fix to avoid NPE, and this morning I am going to make extensions to handle a parameter

Issue is resolved, snapshot version is available on the plugin page

Tried it out - our bigger project now builds fine. So that's good.

However the smaller project still gets an error. Will open a new defect for that one.

Thanks!
