I have a Jenkinsfile with multiple stages and one of them is in fact another job (the deploy one) which can fail in some cases.
I know that I can made prompts using Jenk
This gist (not mine) was one of the better options that I found while trying to implement this functionality too. https://gist.github.com/beercan1989/b66b7643b48434f5bdf7e1c87094acb9
Changed it to a method in a shared library that just did retry or abort for my needs. Also added a max retries and made the timeout variable so that we could change it depending on the job or stage that needs it.
package com.foo.bar.jenkins
def class PipelineHelper {
def steps
PipelineHelper(steps) {
this.steps = steps
}
void retryOrAbort(final Closure> action, int maxAttempts, int timeoutSeconds, final int count = 0) {
steps.echo "Trying action, attempt count is: ${count}"
try {
action.call();
} catch (final exception) {
steps.echo "${exception.toString()}"
steps.timeout(time: timeoutSeconds, unit: 'SECONDS') {
def userChoice = false
try {
userChoice = steps.input(message: 'Retry?', ok: 'Ok', parameters: [
[$class: 'BooleanParameterDefinition', defaultValue: true, description: '', name: 'Check to retry from failed stage']])
} catch (org.jenkinsci.plugins.workflow.steps.FlowInterruptedException e) {
userChoice = false
}
if (userChoice) {
if (count <= maxAttempts) {
steps.echo "Retrying from failed stage."
return retryOrAbort(action, maxAttempts, timeoutMinutes, count + 1)
} else {
steps.echo "Max attempts reached. Will not retry."
throw exception
}
} else {
steps.echo 'Aborting'
throw exception;
}
}
}
}
}
Example usage with a max of 2 retries that waits for 60s for input.
def pipelineHelper = new PipelineHelper(this)
stage ('Retry Example'){
pipelineHelper.retryOrAbort({
node{
echo 'Here is an example'
throw new RuntimeException('This example will fail.')
}
}, 2, 60)
}
Just remember to put nodes inside of the closure so that waiting for an input doesn't block an executor.
If you have the paid jenkins enterprise Cloudbees has a Checkpoint plugin that can better handle this, but it is not planned to be release for open source Jenkins (JENKINS-33846).
