Does gradle.properties have access to environment variables

Question

I looked around and could not find any way of accessing environment variables in my gradle.properties.

What I can do: In my build.gradle I can access environment variables like this System.getenv("MY_VAR"). I would like to do the same in my gradle.properties.

Example of what I want to do: In my gradle.properties replace build.foo=bar with build.foo=System.getenv("BAR")

So far all my attempts to access environment variables from gradle.properties have failed.

Any insight into the matter would be great, thanks!

Answer 1

You can't. gradle.properties is not anything fancy, it is a standard properties file.

You would need to post-process the properties somehow as indicated in this. Currently, Gradle does not offer any such functionality to "custom load" gradle.properties.

Answer 2

Not all environment variables are visible to gradle. If you can name them with the special prefix ORG_GRADLE_PROJECT_ these will be available. You can read about it here

ORG_GRADLE_PROJECT_foo can be accessed as foo within gradle.
