How can I react to a build failure in pipeline?

[Scott Richmond]

I need to be able to do a HTTP POST when the Jenkins Pipeline job finishes in failure due to some issue in the process of doing its tasks. Basically I need to surround the pipeline in a giant try-catch{}. Does pipeline provide functionality to perform final tasks in the event of a failure?

Hi,

It took me a while to find it but it looks like this is the approach

which is also documented ...

... you can find the relating documentation when you use the "Snippet Generator"

looking for the entry "catchError" and then clicking one the question mark.

The final implementation of course depends on your needs. If you wanna stop

the pipeline but doing the cleanup then next example is probably one way to go.

But you also could do a kind of cleanup and proceed with next stage when this

is possible in your case.

A bit unfortune - I say - that such things are not documented here: https://jenkins.io/doc/pipeline/

        // doing some cleanup for stage one

        throw new Exception("Stage One failed!")

    } 

    

    try {

        stage "Two"

        echo "hello world!"

    } catch (all) {

        // doing some cleanup for stage two

        throw new Exception("Stage Two failed!")
