[FIXED] Spring Boot Actuator Info Endpoint Version from Gradle File

Issue

I'd like the /info actuator endpoint from my Spring Boot (1.2.4.RELEASE) application to return the version as specified in the build.gradle file.

In my build.gradle file I have a line as so:

version = '0.0.1-SNAPSHOT'

I am using yaml configuration file. Right now I have the version duplicated as so in application.yml:

info:
    build:
        version: 0.0.1-SNAPSHOT  

Is this possible?

Solution

This exact use case is spelled out in the Boot docs:

http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#production-ready-application-info-automatic-expansion-gradle

So in your build.gradle do this

version = '0.0.1-SNAPSHOT'
processResources {
    expand(project.properties)
}

Your application.yml

info:
  build:
    version: ${version}

1. Make sure to escape any spring placeholders so it doesn't conflict with Gradle. Both use ${} as the replacement token. ${key} should become \${key} . This will affect anything in src/main/resources.

2. Clean/build and deploy your war/jar. Don't run it from your IDE or the placeholder won't be replaced.
