Passing envs into gradle build?

Question

I am using gradlew within a container for a CI build.

ENV values are not being recognized when I add them in the bash shell.

Is there a way of passing the envs into the gradle build parameter or should the above be sufficient?

Answer 1

I'm not really sure about the problem here, is that you cannot read the variables inside gradle?

This question might help: In Gradle, is there a better way to get Environment Variables?

version = System.getenv("JENKINS_BUILD_NUMBER") ?: "0.1-SNAPSHOT"

is working fine in my build.gradle scripts.

Here there is an example:

Well, that should definitely work fine.

that's my build.gradle:

apply plugin: 'java'
apply plugin: 'groovy'

task('hello') {
  println System.getenv("HI")
}

So, if I run:

export HI="hello there"

gradle hello

I get this:

hello there
:hello UP-TO-DATE

This works. Just make sure that the ENV variables are correctly defined in your CI conf.
