如何从Java应用程序获取Jenkins env变量？

Question

I am running integration tests written in Java inside of a Jenkins pipeline.

In my pipeline I am setting the appium.app.branch variable( env.'appium.app.branch' = branch ). Then I call 'mvn verify'. The problem is that in my Java test code I can't get appium.app.branch value. System.getenv("appium.app.branch") call retutns null .

How to get the value?

Answer 1

Use withEnv() {} block. Something like this should work

node {
  withEnv(["appium.app.branch=${branch}"]) {
    sh 'mvn verify'
  }
}

However I am not sure about the variable name, bash for example doesn't support variable names with dots. Try to use some alphanumeric + underscore name like APPIUM_APP_BRANCH
