The /actuator/info endpoint, by default, is empty. We will need to add the following settings to application.properties so that we can see the basic information:

info.app.name=@name@
info.app.description=@description@
[email protected]@
[email protected]@
[email protected]@

We can use @..@ placeholders to refer to our Maven properties because we use spring-boot-starter-parent. Beside this basic information, we can add build information into this endpoint by adding the build-info goal to the spring-boot-maven-plugin:

<plugin>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-maven-plugin</artifactId>
  ...
  <executions>
    <execution>
      <goals>
        <goal>build-info</goal>
      </goals>
    </execution>
    ...
  </executions>
</plugin>

We can add the following git-commit-id-plugin to add the Git commit information to the endpoint:

<build>
   <plugins>
     <plugin>
       <groupId>pl.project13.maven</groupId>
       <artifactId>git-commit-id-plugin</artifactId>
     </plugin>
    <plugin>
    ...
  </plugins> 
</build>

With these plugins, we can use the /actuator/info endpoint to verify whether the application has the current build and commit to detect situations such as having an old incompatible version of the application running.
