Jenkins重试代码块不会多次执行

Question

重试块不起作用。它只执行一次。

我使用echo和error测试了retry块，它会重试指定的次数。但在测试timeout时，重试只执行一次。

pipeline {
    agent any
    stages {
        stage("Deploy") {
            steps {
                retry(3) {
                    timeout(time: 1, unit: 'SECONDS') {
                        sleep 3
                    }
                }
                
                echo "after timeout"
            }
        }
    }
}

如果我尝试超时30秒和睡眠50秒，它仍然不起作用。

        }
    }
}

Answer 1

它无法工作，因为您将超时设置为1秒。

设置至少1分钟或至少30秒

timeout(time: 1, unit: 'MINUTES')

Answer 2

在retry块中使用timeout时，这似乎是一个已知的问题：

JENKINS-51454

JENKINS-51928

你必须自己去捕捉异常

以下是解决此问题的方法：

注意：try-catch子句在timeout块内，不包含timeout块

pipeline {
    agent any
    stages {
        stage("Deploy") {
            steps {
                retry(3) {
                    timeout(time: 1, unit: 'SECONDS') {
                        script{
                            try {
                                sleep(3)
                            } catch (err) {
                                error 'Timeout has been exceeded'
                            }
                        }
                    }
                }
                echo "after timeout"
            }
        }
    }
}
