I have implemented retries around some code in Jenkins pipeline.
retry(2) {
// code
}
Is there a way to identify when a retry has happened? Besides just manually checking console logs. Would like to identify builds which have retried some flakey code and send notification.
I don't know of a way to know that inside the retry{ } block.
You could try a fairly generic solution (even maybe as a global var in a shared pipeline library), such as using a try catch block (since the retry will wait for an exception):
int retryAttempts = 0
retry(2) {
try {
if (retryAttempts>0) {
// a retry is occurring
// Do pre-retry logic, if needed
...
}
// Do stuff
.....
} catch (e) {
retryAttempts++ // a retry WILL occur
throw e // rethrow to trigger retry
}
}
if (retryAttempts>0) {
// a retry has occurred
// Do post-retry logic, if needed
...
}
