Question

我是RapidClipse IDE的新手，因为我的组织要求我用它研究和开发。在安装了2.3.1版本的Windows版本之后，我创建了一个项目，但UI设计器显示错误，并且窗口小部件调色板没有显示任何内容。您可以在下面找到完整的堆栈跟踪：

Answer 1

我能够解决这个问题。它可能是来自RapidClipse开发人员的错误。这就是我所做的：

创建项目时，用于显示设计器和调色板的UI库不会下载，因此您必须下载以下内容：

XDEV服务器-AA
XDEV服务器的UI

将它们包含在您的库路径中。然后右键单击项目选择maven并更新项目。重新启动RapidClipse IDE
