jenkins pipeline warnings graph

Question

I started to migrate some jobs in jenkins to pipeline execution.

Is there any chance to see the warnings graph in multi branch pipeline jobs? Within my older projects I can configure the graphs with "Configure the trend graph" option. These option will crash in the pipeline syntax tool.

Is there any option to make the graph visible?

I have in my Jenkinsfile:

stage ('Warnings gcc') {
    step([$class: 'WarningsPublisher', canComputeNew: false, canResolveRelativePaths: false, defaultEncoding: '', excludePattern: '', healthy: '', includePattern: '', messagesPattern: '', parserConfigurations: [[parserName: 'GNU Make + GNU C Compiler (gcc)', pattern: 'error_and_warnings.txt']], unHealthy: ''])
}   

stage ('Warnings clang') {
    step([$class: 'WarningsPublisher', canComputeNew: false, canResolveRelativePaths: false, defaultEncoding: '', excludePattern: '', healthy: '', includePattern: '', messagesPattern: '', parserConfigurations: [[parserName: 'Clang (LLVM based)', pattern: 'error_and_warnings_clang.txt']], unHealthy: ''])
} 

The reports will be generated but no graph is displayed.

UPDATE: Now it still did not work but it is also impossible to use the snipped generator for the warnings plugin.

Entering a file name in the snipped generator for the warning plugin results in a java null pointer exception:

javax.servlet.ServletException: java.lang.NullPointerException

Mentioned in the revision log for the warnings plugin V 4.56:

Fixed deactivation of trend graphs (using the analysis collector plug-in)

But I use 4.57 and it still did not display any graph!

I posted the problem also to jenkins user list (no feedback for weeks) and also added bug report and bug report

Can anyone reproduce the problem or is the multi-branch pipeline simply still broken at all? Seems to be that there are not so much users for this plugin...

Answer 1

These issues have been resolved with the latest versions of both Jenkins, the pipelines plugin[s], and the plugins you have mentioned above.

Additionally, the bugs you specifically reported have been resolved:

1. [FIXED JENKINS-39553] Make GitHub plugin BuildableItem aware (#153)
2. [FIXED JENKINS-39532] Do not access the workspace for pipelines

Update your Jenkins instance and all of your plugins (some of them have interdependencies on others) and after the suggested restart you should be able to display the graph successfully.
