We have implemented a retry mechanism in our pipeline and if the step fails in the first run, it is retried and then succeeds, the stage is still shown as failed, but the build is green.

See the attached screenshot. The second stage is shown as failed which was retried once.

To reproduce:

node {
    stage "1"
    stage "2"
    def counter = 0
    waitUntil {
        counter++
        try {
            if (counter == 1) {
                sh "false"
            }
            return true
        }
        catch (e) {
            return false
        }
    }
    stage "3"
}
