Blue Ocean - Candidates
Blue OCean doesn't display the log messages and error messages generated by plugin wrapping steps (and maybe other kinds of messages).
This make it particularly difficult to understand build failures caused by the environment (e.g. credentials not found).
How to reproduce
Create a pipeline for https://github.com/cyrille-leclerc/a-broken-jenkinsfile/
Sample
Credentials not found in "withCredentials()"
Jenkinsfile
node { checkout scm stage('Build') { withCredentials([ usernamePassword( credentialsId: 'credentials_dont_exist', passwordVariable: 'MY_PASSWORD', usernameVariable: 'MY_USERNAME')]) { sh "./mvnw clean install" } } }
'classic' build logs
[Pipeline] stage [Pipeline] { (Build) [Pipeline] withCredentials [Pipeline] // withCredentials [Pipeline] } [Pipeline] // stage [Pipeline] } [Pipeline] // node [Pipeline] End of Pipeline GitHub has been notified of this commit’s build result org.jenkinsci.plugins.credentialsbinding.impl.CredentialNotFoundException: credentials_dont_exist at org.jenkinsci.plugins.credentialsbinding.MultiBinding.getCredentials(MultiBinding.java:153) at org.jenkinsci.plugins.credentialsbinding.impl.UsernamePasswordMultiBinding.bind(UsernamePasswordMultiBinding.java:76) at org.jenkinsci.plugins.credentialsbinding.impl.BindingStep$Execution.start(BindingStep.java:114) at org.jenkinsci.plugins.workflow.cps.DSL.invokeStep(DSL.java:222) ... Finished: FAILURE
Blue Ocean Build View
The Blue Ocean build view doesn't display any information to help to understand that the cause is a credentials not found in "withCredentials".

JENKINS-45380 Errors on block-scoped steps not represented in Blue Ocean

- Open

So, this is a bigger matter than it may look at first glance - JENKINS-45380, e.g., is the same thing, really. The core issue is that Blue Ocean doesn't represent block-scoped steps at all currently. I think changing Blue Ocean accordingly is probably going to be a fairly complex thing - the NodeGraphVisitor stuff will need to change to be aware of start/end nodes for steps other than just parallel and stage like it is currently, there'll need to be some design work determining how to visually represent block-scoped steps (show both the start and end, with other steps within indented maybe? I dunno, I am not a UI designer, to say the least!), etc...
