License for existing plugins without license notices.
Hello. JENKINS-21270 points plugins without license information: https://issues.jenkins-ci.org/browse/JENKINS-21270 Parameterized-trigger-plugin is also pointed. As I was just planning to make its new release merging some pull requests, I'm going to add a license notice to that if I can. Please let me know how can I decide its license. What is required to put it under MIT license? Does it require agreements by someone? It contains no LICENSE file. Some of files contain license notices in their header comments, but many of them including core logic files contain no license notices. As parameterized-trigger-plugin is contributed by many developers, I'm not sure who is responsible for its license... Does anyone know how to do in that case? * Plugins hosted in Jenkins repository without any license notice can be treated under MIT License ? * Requires an agreement of the developer originally developed that plugin? * Requires agreements of all developers contributed that plugin? * No one can decide its license ?

Re: License for existing plugins without license notices.
https://wiki.jenkins-ci.org/display/JENKINS/Before+starting+a+new+plugin States that: If nothing is defined, your code will be assumed to fall under the MIT license http://en.wikipedia.org/wiki/MIT_License terms, so it should be no problem adding the MIT license there. To be on the safe side though: try to contact the maintainers and see what they think. On 21 January 2014 15:22, Ikedam de...@ikedam.jp wrote: Hello.

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: 500Exception: 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?

RE: Probable class loading issue / conflict between plugins
Hi Peter, OffTopic Interestingly enough we are planning on pushing results back from the cucumber plugin to another system – so I wonder if there is some commonality that the plugin should expose rather than requiring many plugins parsing the same files. /OffTopic /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.

Publishing cucumber test results
(Moving this topic to a new thread so that the main issue I'm having with the other one doesn't get overlooked!) Hi Peter, OffTopic Interestingly enough we are planning on pushing results back from the cucumber plugin to another system – so I wonder if there is some commonality that the plugin should expose rather than requiring many plugins parsing the same files. /OffTopic /James Hi James, I think there may be some benefit. If we could structure it so that the user wouldn't need to enter cucumber configuration related settings more than once, that would be nice. Setting up the gherkin parser within a common codebase would save some code. In my case, I implemented a gherkin callback to generate HP Quality Center specific objects that worked pretty well. The formatter / reporter push based parsing mechanism is fairly easy to use so I'm not sure having the common codebase deliver an additional API for the test cases would be to beneficial. Any particular benefits that you're thinking of? Pete -- You received this message because you are subscribed to the Google Groups Jenkins Developers group.

Best way to load a file into a Jenkins plugin
Hi, I'm writing a jenkins build plugin and the build needs to make some HTTPS calls but the server requires auth with a certificate and private key. What would be the best way (from the user's point of view) to allow him to load a custom keystore from the project configuration page, under my plugin's section as I haven't seen Jenkins to support file data type and as the keystore is in binary format i can't create text filed where he can paste the certificate or something like this.
