Set environment variable in Gradle build: Easy steps

Introduction

If you're working with Gradle builds, you may need to set environment variables to properly configure your project. In this article, we'll go over the easy steps to set environment variables in your Gradle build.

Step 1: Define the variable

The first step is to define the environment variable in your operating system. This can be done by adding the variable to your system's environment variables. For example, if you want to define a variable called "MY_VAR", you can add it to your system's environment variables with the value you need.

Step 2: Access the variable in build.gradle

Once you have defined your environment variable, you can access it in your Gradle build by using the System.getenv() method. For example, if you want to use the value of "MY_VAR" in your build.gradle file, you can add the following code:

task myTask {
    doLast {
        def myVar = System.getenv("MY_VAR")
        println "The value of MY_VAR is: ${myVar}"
    }
}

This code creates a task called "myTask" that prints the value of the "MY_VAR" environment variable. You can use this code as a template to access any environment variable in your Gradle build.

Step 3: Use the variable in your build

Now that you can access your environment variable in your Gradle build, you can use it to configure your project. For example, if you want to use the value of "MY_VAR" as a property in your project, you can add the following code to your build.gradle file:

ext {
    myVar = System.getenv("MY_VAR")
}

task myTask {
    doLast {
        println "The value of MY_VAR is: ${myVar}"
    }
}

This code creates a property called "myVar" that is set to the value of the "MY_VAR" environment variable. You can then use this property in your build as needed.

Conclusion

Setting environment variables in your Gradle build is easy and can be done in just a few simple steps. By following the steps outlined in this article, you can access and use environment variables in your Gradle build to properly configure your project.
