如何在jenkinsFIle jenkins 2中为构建过程插件调用注入环境变量。x管道

I'm trying to migrate my project from jenkins 1 to jenkins 2.x using pipeline as code or Jenkinsfile.
But I don't see any option in snippet generator to generate environment injector plugin into a script in Jenkinsfile.

我想把我的项目从jenkins 1移到jenkins 2。使用管道作为代码或Jenkinsfile。但是我没有看到在代码片段生成器中有任何选项可以在Jenkinsfile中生成环境注入器插件。

Anyone can help?

I'm assuming that you want to read properties from a specific file and inject them as environment variables?

我假设您想要从一个特定的文件读取属性并将其注入到环境变量中?

If so, this is a solution:

如果是这样，这是一个解决方案:

Create the file that will contain the environment properties

创建包含环境属性的文件。
- You create some properties file called project.properties with following content:
  
  创建一个名为project的属性文件。属性与以下内容:
  
  PROJECT_VERSION='1.4.34'
  
  PROJECT_VERSION = ' 1.4.34 '

Then, on your pipeline code, you've to add the following code in order to be able to read the file and inject read variables as environment variables:

然后，在您的管道代码中，您必须添加以下代码，以便能够读取文件并将读取的变量注入到环境变量中:

node { load "${WORKSPACE}\\project.properties" // assuming that props file is in Jenkins Job's workspace echo "PROJECT VERSION: ${PROJECT_VERSION}" }

节点负载“$ { WORKSPACE } { \ \项目。属性“//假设道具文件在Jenkins工作的工作区echo”项目版本:${PROJECT_VERSION}

First line read and inject variable PROJECT_VERSION as environment variable
第一行读取并注入变量PROJECT_VERSION作为环境变量。
Second line is just to print read variable to make sure that everything worked seamlessly
第二行是打印读取变量，以确保所有操作都是无缝的。

In general, you can use other plugins by using their Java style invocation.

通常，您可以使用它们的Java风格调用来使用其他插件。

i.e.

即。

step([$class: 'classname', parametername: 'value'])

I used this example for read a properties file and use it in a pipeline stage:

我使用这个示例来读取属性文件，并将其用于管道阶段:

node(){
    file = readFile('params.txt')
    prop=[:]
    file.eachLine{ line ->
      l=line.split("=")
      prop[l[0]]=l[1]
   }
   withEnv(['MyVar1='+prop["MyVar1"],'MyVar2='+prop["MyVar2"],'MyVar3='+prop["MyVar3]]){        
     stage('RUN_TEST'){
       echo env.MyVar1
       echo env.MyVar2
       echo env.MyVar3
       sh"echo $MyVar1"
     }
  }
}
