clover jenkins plugin link "clover summary report error"

Hi,

 

A Clover jenkins plugin issue after couple runs of my code coverage build on jenkins.

The code coverage tracking graph is gone.

The summary line of each job shows this: "Clover Code Coverage - null% method null, conditional null, statement null. "

Clicking on " Clover Summary Report" give me  an exception as below:

By digging into jenkins log, I found the exception message:

 

Sep 02, 2016 9:50:41 AM hudson.ExpressionFactory2$JexlExpression evaluate

WARNING: Caught exception evaluating: it.elementCoverage in /job/nsx-code-coverage-ccp-unit/43/. Reason: java.lang.reflect.InvocationTargetException

 

Is this path correct?

 

By looking into github code, I pinned down the problem to this line:

https://github.com/jenkinsci/clover-plugin/blob/master/src/main/java/hudson/plugins/clover/CloverPublisher.java

 

 

static File getCloverXmlReport(Run<?, ?> build) {
 
    return new File(build.getRootDir(), "clover.xml");
 
}

 

 

Is build.getRootDir() the right way to get correct path for clover.xml?

Hi Will, your issue sounds similar to the issue fixed in recently merged pull-request:

https://github.com/jenkinsci/clover-plugin/commit/ec07020068e5e1b23d12053d42eb2149629fac4b 

Please note that there is no official release with this fix yet. You may want to try the fix by building a snapshot version (git clone + mvn install) and installing it in Jenkins.
