使用 Spring Boot Gradle 插件和 IntelliJ 设置环境变量

Question

My question is about environment variables. I am using the Spring Boot Gradle plugin and developing in Intellij 14 on Windows.

I'm trying to get some Pub/Sub example code for Google API's working, but I don't think this is the main point of my question (Noted here since I could be wrong!) If not running on AppEngine, the sample code has a number of ways that you can satisfy it by supplying a file with authentication credentials. I currently have no plans to use AppEngine.

I am asked to set an environment variable named GOOGLE_APPLICATION_CREDENTIALS and after some small amount of hair-pulling I've learned that a system property will not suffice. It must be an environment variable.

I would like to do this in a way that adjusts the environment for only this IntelliJ project and not for everything on the machine. Normally in IntelliJ I would do this by adding the environment variable to the launch configuration options. Since I am using the Spring Boot Gradle plugin, I have a 'bootRun' launch configuration for my project. The launch configuration options screen has the following major options: Name, Gradle Project, Tasks, VM Options, Script Parameters, Before Launch

There is NO option for Environment Variables.

I am aware that I could probably fix this problem by doing one of the following:

• Add the environment variable under the windows system control panel
• Stop using the Spring Boot plugin so that the 'Environment Variables' section of the launch configuration options comes back as an option

What I am hoping is that there is another option I'm not aware of due to my lack of knowledge about Spring [Boot] and/or Gradle.

Answer 1

In the Gradle Spring Boot plugin, you can set environment variables as an array of key:value pairs.

bootRun {
    environment = ["GOOGLE_APPLICATION_CREDENTIALS": "[PATH TO JSON]" ]
}

Answer 2

Set your environment variable in gradle like below

test {
       environment "GOOGLE_APPLICATION_CREDENTIALS", "<path_to_json>"
     }

Answer 3

You can set the environment variable in the build.gradle below:

test {
    environment "GOOGLE_APPLICATION_CREDENTIALS", "${project.file("/src/test/resources/service-account-data.json")}"
     }

hopefully, this helps someone out. Enjoy!

Answer 4

You can also try to do this from the command line. You need to set the bootRun.systemProperties to the gradle's system properties.

This is how to do this in build.gradle :

bootRun.systemProperties = System.properties

and then you can just run:

gradle bootRun -DGOOGLE_APPLICATION_CREDENTIALS=/path/to/json
