SpringBoot spring-boot-starter-actuator not read git.properties file

I want to used the spring-boot-starter-actuator to expose git info on server. And i already generated the file 'git.properties' into target/classes/, But the filed git is empty when access the /actuator/info.

The spring-boot version: 2.5.8 The jdk version: 1.8.0_321

The config in application.yml:

management:
  endpoints:
    web:
      exposure:
        include: 'health,metrics,info'
  info:
    git:
      enabled: true
      mode: full

The maven pom file:

<build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <excludes>
                    <exclude>*.properties</exclude>
                    <exclude>*.xml</exclude>
                </excludes>
            </resource>
        </resources>

                    <!-- generated git.properties file-->
                    <generateGitPropertiesFile>true</generateGitPropertiesFile>
<!--                    <generateGitPropertiesFilename>${project.build.outputDirectory}/git.properties</generateGitPropertiesFilename>-->
                    <format>json</format>
                    <gitDescribe>
                        <skip>false</skip>
                        <always>false</always>
                        <abbrev>7</abbrev>
                        <dirty>-dirty</dirty>
                    </gitDescribe>
                </configuration>
            </plugin>
        </plugins>
    </build>

When i access the /actuator/info and get

{"git":{},"grpc.server":{"port":9119,"services":{"developer.FlinkDeveloper":["CancelFlinkJob","GetFlinkJobsByUrl","GetFlinkJobStatus","ParseFlinkJobToGraph","SubmitFlinkJob","ValidateFlinkJob","ValidateFlinkJobContext"],"grpc.health.v1.Health":["Check","Watch"],"grpc.reflection.v1alpha.ServerReflection":["ServerReflectionInfo"]}}}

Run the app command line:

java -jar xxx.jar -Dspring.config.location=xxxx/target/classes/application.yml  --logging.config=xxxx/src/main/resources/log4j2.xml

How can i make the git.properties work when start the server. Thanks.

You have configured the plugin to generate json:

<format>json</format>

You need to use the default properties format. This can be achieved by removing the configuration of the format.
