我正在用amazon opendistro为elasticsearch编写一个调度程序插件。我在使用新版本7.9.1时遇到了一些问题，在使用gradle版本构建项目时，我遇到了这个错误：

Execution failed for task ':opendistro-job-scheduler-project-scheduler:dependencyLicenses'.
> Missing SHA for jackson-databind-2.11.3.jar. Run "gradle updateSHAs" to create them

我导入的每个库（比如json或httpclient）都会出现这个错误。如果我运行“gradle update shah”，我会得到以下结果：

Task 'SHAs' not found in root project 'opendistro-job-scheduler'.

你知道吗？这是我的毕业档案：
