例如，如果我有一个变量 -

How do I invoke Global environment variables in Jenkinsfile?
For example, if I have a variable -

如何在 groovy 脚本中使用它?

How do I use it in the groovy script?

我尝试了 ${credentialsId}，但没有成功.它只会给出错误:

I tried ${credentialsId}, but it didn't work. It will just give error:

java.lang.NoSuchMethodError: No such DSL method '$' found among steps [ArtifactoryGradleBuild, ........

推荐答案

在 Jenkinsfile 中，你有 "使用环境"其中提到:

In a Jenkinsfile, you have the "Working with the Environment" which mentions:

可从 Jenkins Pipeline 中访问的环境变量的完整列表记录在 localhost:8080/pipeline-syntax/globals#env，

The full list of environment variables accessible from within Jenkins Pipeline is documented at localhost:8080/pipeline-syntax/globals#env,

语法是${env.xxx}，如:

node {
    echo "Running ${env.BUILD_ID} on ${env.JENKINS_URL}"
}

另请参阅 "管理环境".

See also "Managing the Environment".

如何将全局变量传递给 Jenkinsfile?
当我说全局变量时——我的意思是在

How can I pass the Global variables to the Jenkinsfile?
When I say Global variables - I mean in

Jenkins -> Manage Jenkins -> Configure System -> Global properties -> Environment variables

请参阅设置环境变量";

在 Jenkins 流水线中设置环境变量可以通过 withEnv 步骤完成，该步骤允许为给定的流水线脚本块覆盖指定的环境变量，例如:

Setting an environment variable within a Jenkins Pipeline can be done with the withEnv step, which allows overriding specified environment variables for a given block of Pipeline Script, for example:

Jenkinsfile(管道脚本)

Jenkinsfile (Pipeline Script)

node {
    /* .. snip .. */
    withEnv(["NAME=value"]) {
        ... your job
    }
}
