Question

我是google webtoolkit for eclipse的新手。在为eclipse连续安装GWT插件并启动我的第一个项目后，我收到错误“invocation of com.google.gwt.user.tools.WebAppCreator failed, See the error log for more details”。知道解决方案的任何人都可以提供帮感谢。

这是错误日志;

Answer 1

我通过更改工作区来解决这个问题。旧工作区目录的权限很好，我仍然不知道它有什么问题。

Answer 2

取消选中“新建Web应用程序项目”窗口中的“生成项目示例代码”复选框，解决了我的问题。

Answer 3

从现有工作空间中删除元数据文件夹，然后重新启动eclipse。这是我OS=Ubuntu-12.04的隐藏文件夹。要显示Ctrl+h。

Answer 4

您是否在项目中配置了GWT SDK？

Answer 5

取消选择“使用Google Web Toolkit”是我的解决方案。可能是我的谷歌网络工具包（GWT）安装有一些问题。

Answer 6

我按照以下步骤解决了这个问题： 1.转到控制面板＆gt;高级系统设置＆gt;环境变量 2.从用户变量和系统变量中删除类路径。

我希望这有效。

Answer 7

我通过取消选中“新建Web应用程序项目”窗口中的“生成项目示例代码”复选框来修复此问题
