Jenkinsfile:
pipeline {
agent any
stages {
stage('Test') {
steps {
wrap([$class: 'org.boxboat.plugins.lxd.HelloWorldWrapper']) {
sh '''
ls /tmp
cat /tmp/jenkins'''
}
}
}
stage('Publish') {
steps {
wrap([$class: 'org.boxboat.plugins.lxd.HelloWorldWrapper']) {
sh '''
ls /tmp
cat /tmp/jenkins'''
}
}
}
}
}
When I hit "Save and Run" in the Blue Ocean editor, it does nothing and gives no indication of an error. When I browse the network requests tab I see a request to `http://localhost:8080/jenkins/pipeline-model-converter/toJenkinsfile` that returned 200, but included a failure message:

},

[JENKINS-44451] Cannot save pipeline with a wrapper
This looks to be an issue in validation not handling metasteps correctly. Will investigate.
So yeah, the problem is that validation doesn't work for metasteps like wrap. I don't think it ever will work, but I'll improve the error messaging. And in the meantime, SimpleBuildWrapper classes can have a @Symbol added to their descriptor, so they can be invoked like normal steps.
Ok, I'm wrong, it actually does work. And in fact, I can't reproduce this!
I believe the editor's JSON generation has improved since this was opened, because I can't reproduce it now. If you can reproduce it with Blue Ocean 1.3.1 or later and Declarative 1.2.4 or later, please reopen this.

added a comment - I'm having the same issue. I can't add a delegate class through the text input field in the Blue Ocean UI.
Whatever you enter is interpreted as String - not as a class.

added a comment - using Blue Ocean 1.4.2 Max von Preuschen
added a comment - Reopening this issue, since it seems there is no possibility to enter a valid value into the "Delegate" text input field.
- Expecting "class jenkins.tasks.SimpleBuildWrapper" for parameter "delegate" but got "..." of type class java.lang.String instead
