# 86.2 生成Git信息

Maven和Gradle都支持生成一个`git.properties`文件，该文件包含项目构建时`git`源码的仓库状态。对于Maven用户来说，`spring-boot-starter-parent` POM包含一个预配置的插件去产生一个`git.properties`文件，只需简单的将以下声明添加到POM中：

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

Gradle用户可以使用[gradle-git-properties](https://plugins.gradle.org/plugin/com.gorylenko.gradle-git-properties)插件实现相同效果：

```
plugins {
    id "com.gorylenko.gradle-git-properties" version "1.4.17"
}
```

**注** `git.properties`中的提交时间需要符合以下格式：`yyyy-MM-dd’T’HH:mm:ssZ`。这是上面列出的两个插件的默认格式。使用这种格式可以将时间解析为`Date`，并将其格式序列化为JSON时，由Jackson的日期序列化配置设置控制。
