使用Git进行Gradle版本控制

我正在尝试使用Git在Gradle中创建自动版本控制，但是在构建应用程序时出现了一些错误。我的操作系统是Windows。

def getVerName = { ->
    try {
        def stdout = new ByteArrayOutputStream()
        exec {
            commandLine "git", "describe", "--long"
            standardOutput = stdout
        }
        def result = stdout.toString()
        result = result.trim()
        return result
    } catch (ignored) {
        return null
    }
}

这是我的异常的堆栈跟踪

我的GIT路径：C:\Program Files\Git\cmd。设置PATH局部变量什么也不做。从StackTrace中，您可以看到Gradle在app目录中正在寻找git.exe。如何改变那条路？
