jenkins plugin to fail build based on console output

Question

Is there a plugin to fail a build if a pattern occurs on the console output?

For example:

Build Action - success
Build Action - success
Build Action - error_pattern
Build Action - success

Let's assume that the Jenkins build process does not fail the build on error_pattern, I need to have an external fail trigger of some sort.

EDIT

Looking for a solution to fail the build during, not a post build task.

I've used this answer as the basis of a pipeline script. In the "Build" stage I have two parallel sub-stages - one of them is doing the actual build and outputting to a log, whilst the other sub-stage is grepping the same log. I've negated the exit code (! grep) so that it'll error when the "ERROR:" string is found. Thanks to the failFast setting, this will cause the whole "Build" stage to fail as soon as the string is found. There's an extra grep at the end of the first sub-stage, in case an error was produced right at the end.

I'm tracking the build status with a variable (BUILD_COMPLETE).

pipeline {
    agent {
        label 'master'
    }
    environment {
        BUILD_COMPLETE = false
    }
    stages {
        stage('Build') {
            failFast true
            parallel {
                stage('Building') {
                    steps {
                        sh 'echo foo | tee output.log'
                        sleep 5
                        sh 'echo bar | tee -a output.log'
                        sleep 5
                        sh 'echo ERROR: baz | tee -a output.log'
                        sleep 5
                        sh 'echo qux | tee -a output.log'
                        sleep 5

                        sh '! grep "^ERROR:" output.log'

                        script {
                            BUILD_COMPLETE = true
                        }
                    }
                }
                stage('Monitoring the logs') {
                    steps {
                        script {
                            while (BUILD_COMPLETE != true) {
                                sh '! grep "^ERROR:" output.log'
                                sleep 1
                            }
                        }
                    }
                }
            }
        }
    }
}

You should try the Post Build Task plugin. You can search for a pattern and then launch a script.

edit: There is also Text finder plugin, looks better for your problem
