我已经下载了Wos2 Developer Studio，下载了碳4.2并将其作为服务器添加到开发者工作室。我开始使用碳并进入碳管理控制台，我添加了以下功能库
http://dist.wso2.org/p2/carbon/releases/turing/
并安装了企业服务总线。我创建了一个ESB Config项目并添加了一个Rest API artefact。我成功部署了它并且工作正常。但是，当我使用“添加和删除..”删除它时，它告诉我它已删除它，但实际上没有。因此，当我重新启动服务器时，我会在部署碳应用程序时出现“错误”，即使在服务器上部署的任何内容都没有显示。然后我再也无法部署任何东西，包括新项目。选择服务器“清理”和“发布”不能解决问题吗？
