如何在Jenkinsfile中将字符串转换为整数? [英] How can I do string to integer conversion in a Jenkinsfile?

问题描述

我的Jenkins文件中包含以下内容:

I have the following in my Jenkinsfile:

pipeline {
    agent none
    environment {
        timeout_mins = 1
    }
    options {
        timeout(time: "${env.timeout_mins}", unit: 'MINUTES')
    }
    stages {
        stage("test print") {
            steps {
                echo "timeout_mins: ${env.timeout_mins}"
                sh "sleep 120"
            }
        }
    }
}

我想在多个地方重复使用timeout_mins之类的环境参数，但是对于某些插件，需要在某些地方将其转换为整数.我在上面的示例中遇到的错误如下:

I'd like to re-use environment params such as timeout_mins in multiple places, but need to convert it to integer in certain places for certain plugins. The error I get with the above example is as follows:

有人可以在Jenkinsfile中将String转换为int吗?

Does any one have a way to convert from String to int in Jenkinsfile?

我尝试过 time: env.timeout_mins，但这会产生一个空值.

I tried time: env.timeout_mins, but that yields a null.

time: ${env.timeout_mins}，得出: WorkflowScript:7:方法调用参数@第7行，第23列. 超时(时间:$ {env.timeout_mins}，单位:"MINUTES")

time: ${env.timeout_mins}, yields: WorkflowScript: 7: Method call arguments @ line 7, column 23. timeout(time: ${env.timeout_mins}, unit: 'MINUTES')

time: ${env.timeout_mins}.toInteger()，与上面相同

time: ${env.timeout_mins.toInteger()}，与上面相同

还有什么我可以尝试的吗?

Any other things I can try?

推荐答案

并不是转换失败，只是您不能在options块中引用环境变量.

it's not the conversion that's failing, it's just that you can't reference environment variables in the options block.

这也会失败(空指针异常):

this also fails (nullpointer exception):

pipeline {
    agent none
    environment {
        timeout_mins = 'MINUTES'
    }
    options {
        timeout(time: 1, unit: env.timeout_mins)
    }
    stages {
        stage("test print") {
            steps {
                echo "timeout_mins: ${env.timeout_mins}"
                sh "sleep 120"
            }
        }
    }
}

这有效:

def timeout_in_minutes = 1

pipeline {
    agent none
    options {
        timeout(time: timeout_in_minutes, unit: 'MINUTES')
    }
    stages {
        stage("test print") {
            steps {
                echo "timeout_in_minutes: ${env.timeout_in_minutes}"
                sh "sleep 120"
            }
        }
    }
}
