Spring Cloud Data Flow无法上传包。信息库[本地]中的软件包[test-stream-comments：1.0.0]已存在

Question

我已经在Spring云数据流中创建了一些流。我部署了它们，它们运行平稳。然后取消部署它们，当我尝试通过单击“部署流”重新部署流时，出现红色错误提示，提示"Spring Cloud Data Flow Failed to upload the package. Package [test-stream-comments:1.0.0] in Repository [local] already exists."

这是否意味着我必须销毁该流，然后重新创建和部署该流？通过单击按钮无法实现部署和取消部署流的目的吗？

Answer 1

尝试运行spring-cloud-dataflow-shell并运行：

stream undeploy facebook-stream-comments。

然后尝试从Web UI再次部署此流。

更新。

我继续研究并找到其他解决该问题的底层方法：

我连接到MySql db并删除了与不良软件包链接的所有记录：

delete from `dataflow`.`skipper_status` where (`id` = '...');
delete from `dataflow`.`skipper_info` where (`id` = '...');
delete from `dataflow`.`skipper_app_deployer_data` where (`id` = '...');
delete from `dataflow`.`skipper_release` where (`id` = '...');
delete from `dataflow`.`skipper_package_file` where (`id` = '...');
delete from `dataflow`.`skipper_package_metadata` where (`id` = '...');

并重新启动`spring-cloud-skipper-server.jar

但是这种方式很困难而且不正确（可能）。>
