我无法启动我的STS 3.3。它不能从提供以下例外开始

这里有什么问题？

Answer 1

这通常是插件保存的临时文件的问题。这些步骤应该可以帮助您：

• 检查YOUR_WORKSPACE/.metadata/.plugins/org.eclipse.jdt.core/有很多索引文件。有时候删除它们会有帮助。还可以使用-clean启动您的eclipse。
• 根据您的问题，我认为从文件系统中移动了一些文件，可能是一个新的位置导致了这个错误。试着检查一下。
• 刷新所有您的项目。
• 尝试创建一个新工作区并检查。
• 如果没有效果，就试试re-installing吧。

此外，如果您决定不使用STS，，您可以始终使用Eclipse和STS插件.。

希望能帮上忙。:)
