Anyone? I didn’t expect to have to require a plugin-first classloader unless the conflicting library was in core? Is my use pf persisting 3rd party classes via xStream broken by design (can we only persist internal to the plugin classes?)
Is this just a case of requiring shading of the cucumber classes (in which case anyideas how to do this so that old builds don’t break?) /James From: jenkinsci-dev@googlegroups.com [mailto:jenkinsci-dev@googlegroups.com] On Behalf Of Peter Hayes Sent: 21 January 2014 16:02 To: jenkinsci-dev@googlegroups.com Subject: Probable class loading issue / conflict between plugins Hi, I am writing a custom plugin to publish cucumber test results to a quality center database for internal reporting needs. To do so, I am using the cucumber-jvm gherkin library to process the test result file as was done in the cucumber-testresult-plugin. My code is working fine and processing the results but when I also installed the cucumber-testresult-plugin on my Jenkins instance and used that, I am seeing this error message when trying to display the test results: Status Code: 500 Exception: Stacktrace: java.lang.ClassCastException: gherkin.formatter.model.Tag cannot be cast to gherkin.formatter.model.Tag at org.jenkinsci.plugins.cucumber.jsontestsupport.CucumberTestResult.tally(CucumberTestResult.java:273) at org.jenkinsci.plugins.cucumber.jsontestsupport.CucumberTestResultAction.load(CucumberTestResultAction.java:119) at org.jenkinsci.plugins.cucumber.jsontestsupport.CucumberTestResultAction.getResult(CucumberTestResultAction.java:147) at org.jenkinsci.plugins.cucumber.jsontestsupport.CucumberTestResultAction.getTarget(CucumberTestResultAction.java:174) at org.kohsuke.stapler.Stapler.tryInvoke(Stapler.java:610) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:776) at org.kohsuke.stapler.MetaClass$12.dispatch(MetaClass.java:381) at org.kohsuke.stapler.Stapler.tryInvoke(Stapler.java:683) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:776) I believe this can happen when there are classloader consistency issues. I looked at the code for the cucumber-testresult-plugin and it is using the XStream2[1] class to load the serialized test results from the disk (in the load method above)[2] and then when it goes to process those results in the tally method[3], it blows up. Is there a potential issue in the way the XStream2 class is handling the classloading? I am running this on Jenkins 1.520 Thanks, Peter [1] https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/util/XStream2.java [2] https://github.com/jenkinsci/cucumber-testresult-plugin/blob/master/src/main/java/org/jenkinsci/plugins/cucumber/jsontestsupport/CucumberTestResultAction.java#L111 [3] https://github.com/jenkinsci/cucumber-testresult-plugin/blob/master/src/main/java/org/jenkinsci/plugins/cucumber/jsontestsupport/CucumberTestResult.java#L221 -- You received this message because you are subscribed to the Google Groups "Jenkins Developers" group.
